<s>[INST] PF525 utilizing a Line Reactor I'm curious if it's possible (and safe) to group multiple PF525 drives on a single line reactor. I am designing a panel that contains fourteen (14) 10hp drives and ideally, I don't want to have a line reactor for each individual drive. Can I group 2-3 drives per line reactor, and if so, how do I go about sizing the correct line reactor? Is it as simple as combining the FLA of the 2-3 drives for the individual line reactor or is there some other calculation to utilize? [/INST] Hello Mark, Please review QA13774 All of the relevant information is available through the technote. Thanks \\n </s> |
<s>[INST] PF 700 Minumum Load Does anyone know what the minimum load is that you can put on a particular drive? For example, where in the documentation does it tell me that I can/can't run a 50A load on a 100A rated drive. [/INST] The best performance will always be when the drive has the same current rating as the motor.Matching drives and motors closely also removes the need to adjust the Current Limit parameter, which is normally related to drive rated amps. As a general rule, the drive rated amps can be up to 200% (2 times) the FLA of the motor. If the mismatch is more than 200%, the drive may not be able to control output current correctly. This is due to the internal CT's only measuring current over a small amount of their overall range. [Reference Aid 51640] Hope this helps… - fuzzy logic \\n </s> |

<s>[INST] FactoryTalk Network Manager Hi Guys, who knows about the new Software FactoryTalk Network Manager? I am trying to get the connection with a stratix 5700 but no success. I think i do not know how to really configure the network Manager so that it sees the switch. Now just for the test i have a LAN cable from switch (any port) to the host PC where Network Manager is installed; the IP of the PC is in the same range like the switch. i can not find where to add a new topic/post, that is why i posted this in here, sorry. Any ideas? thank you [/INST] Yes, the .alarm and .faulted bits come from the PF40. You are correct; from this logic, ANY alarm or ANY fault will turn on bit 31. The PF40 does not offer a lot of diagnostics. The parameter list offers parameters 7, 8, and 9 as Fault Code 1, 2 and 3, the three most recent faults. You could use MSG instructions to get the code stored in those three parameters. You would then need to create a look-up table based on data you can find here: https://literature.rockwellautomation.com/idc/groups/literature/documents/um/22b-um001_-en-e.pdf Refer to section 4-3, page 95 of the PDF above. There's nothing wrong with the code. The drive is a simple drive. If you want a lot of useful diagnostics, a PF750 will give much more (at higher cost). This code tells you the drive faulted. You'd have to go to the drive, look at the fault code displayed on the LED display, and then look it up in the user manual. \\n </s> |

<s>[INST] Keep Motor Warm with DC Brake Function Summary: How to setup PF70EC DC Brake to keep motor warm Hi All, I have setup a Powerflex 70EC VFD to DC Brake indefinitely when the VFD is not running, and while it appears I have done everything correctly, it does not appear to engage. I'm using Digital Input 6 set to Stop Mode B which is set to DC brake after a 10 second delay. When the drive is on and not running there is 24V on Digital In6 and nothing is suggesting that it's working.

<s>[INST] K5700 Drives Inverter Overtemp Fault We have a vertical load application with two axes sharing the load using the same K5700. For some reason when we move the axes up or down, we will intermittently get an Inverter Overtemperature FL Fault. So far, we haven't been able to nail down a root cause. It doesn't seem like the torque is causing this problem because we have tried with varying weights and torques, and it doesn't seem like velocity or acceleration are the main factors either because we have tried playing with the speeds. We trend the inverter temp and notice that this alarm occurs when the inverter temp hits 155.6 degrees C. Does anyone have any good ideas as to why this fault might be occurring in our application?

Page 249 says to use a MSG command to get the RA specific exception (to get the fault subcode), page 257 shows how the bits are mapped. Suggestions: Remove the feedback connectors from motor and drive. Inspect each end, inspect the drive pins, motor pins. Look for something wrong with the connector. If there are screw terminations involved, make sure all conductors are properly seated. Make sure you follow Rockwell's grounding practices with regard to drive and motor.

<s>[INST] 1756-HSC Continuous counting... I am using an encoder on a process line and would like to accumulate length of material. I have an encoder wired to a 1756-HSC and am using it to measure cut lengths.I have an application program that runs in a periodic task of 10 ms. The PresentValue[0] is the input to a pulse multiplier:Mode = 1 RelativeWordsize = 32multiplier = 1000000 Output goes to InPlus on an UpDnCounter block.

How can I work around this? Thanks for the Help! [email protected] [/INST] Answer to your issue is in this statement, taken from PMUL online help: When applying this block, it is important to note that the feedback data should not change by more than ½ the word size from one scan to the next, if rotational direction is to be properly differentiated. In the example above, if the feedback device is moving in a clockwise direction such that at scan ‘A’ it reads 0 and then scan ‘B’ it reads –2000, actual change in position is equivalent to +2096 counts in the clockwise direction. However, since these two values are more than ½ the words size, (or more than ½ the rotation of the physical device,) the PMUL instruction calculates that the feedback device rotated in the opposite direction and returns a value of –2000 instead of +2096. So, which is the count range of your HSC ?You have to change the WordSize in PMUL to remain in the right range, following the examples below. Here some examples: count range 65535 to -65536 ---- set WordSize = 17 bitcount range 2047 to -2048 ---- set WordSize = 12 bitcount range 255 to -256 ---- set WordSize = 9 bit Informations are in Logix5000 Process Control & Drives Instructions Reference Manual pages 261-262 Hope this helps… - fuzzy logic \\n </s> |

<s>[INST] Motion planner scan order? Hi there, Anyone knows in what order the axes are dealt with by the motion planner? Is this automatically resolved, so that (when possible!) a whole sequence of MAGs (and MAPCs) is always fully evaluated every Coarse Update? Think: (Axis) -> MAG -> (Axis) -> MAG -> (Axis) Or do I need to arrange the axes by means of naming etc so that complete one-scan evaluation is achieved? Thanks a lot! [/INST] A clarification: Take the example (Axis 3) -> MAG -> (Axis 2) -> MAG -> (Axis 1) Assume that the motion planner evaluates Axis1 first, then Axis2 and last Axis3. That would make Axis1 operate on 2 Course Update Times old values from Axis 3. The question again: Is the motion planner smart enough to evaluate Axis 3 first and Axis 1 last, or is there another way to control the scan order? \\n </s> |

<s>[INST] PF755 master/follower application - recommended encoder Summary: single channel / single ended or dual channel / differentialHi, I have an application in which I am hoping to use two PowerFlex 755 AC drives in a Master / Slave relationship in a roll-to-roll web handling application. My plan is to equip the master drive with a 20-750-ENC-1 single incremental encoder module and to equip my slave drive with a 20-750-DENC-1 dual incremental encoder module. I will have an encoder mounted on both the master motor and on the slave motor. I plan to wire the master encoder to both the master drive (as feedback for the controlled master motor) and to the slave drive (as an external reference). I will wire the slave encoder to the slave drive (as feedback for the controlled slave motor). I am hoping to use the electronic gearing feature to ensure that I can run the slave motor at a fixed ratio of the master motor. Ideally, I am hoping that I can achieve good performance (in terms of accurate speed control without motor cogging) within a 100:1 speed range (motor RPM ranging from 18 - 1800 rpm). With this in mind, I am planning to use a high quality vector duty motor. My application is basically a constant speed application, where the master roll and the slave roll are used to convey a continuous web material through a machine. The speed ratio is nominally always 1:1 because if the rolls do not turn at the same speed, it would either create slack between the two rolls or break the web. This being said, I do need the flexibility to adjust this ratio between approximately 0.998:1 and 1.002:1 to compensate for stretching or shrinking of the web material in a dryer that it passes through. I *think* there is a good chance I would be able to get the performance I want with independent drives (not using electronic gearing) by just entering set points in the desired ratio, using the same acceleration/deceleration settings for both drives, and making sure I issue start and stop commands for both drives at the same time. The reason I'd like to try the electronic gearing feature is because I think it might help me do a better job of coordinating the speeds of the drives during acceleration and deceleration. I figure if it turns out not to be unnecessary, I will only have wasted the extra cost of one dual-encoder module and hopefully I will have learned something about the electronic gearing feature that might help in future, more challenging applications. My question for today is, will single-ended, single-channel encoders of appropriate resolution be sufficient for achieving good speed control? Or will there be some advantage to be gained if I consider using dual-channel, differential encoders? Any advice or suggestions will be greatly appreciated. Thanks and best regards, Paul [/INST] Consider using an encoder splitter on the master encoder signal - master encoder goes into the splitter; output1 goes to the master drive, output 2 goes to the follower drive. https://www.motrona.com/en/products/signal-converters/level-converters-signal-splitters/gv210-pulse-switch-distributor-and-splitter-for-incremental-encoder-signals.html I think I'd go with differential encoders myself. In all other respects, you've got it wrapped up pretty well. \\n </s> |

<s>[INST] Using motor terminator for cable length more than 189 A Rockwell 1204-TFB2 motor terminator with the serial number: MEAB30Z6 has been bought in order to reduce PWM peak voltages at the motor terminal. The VFD and the motor specifications are as the following: VFD Power: 580 kW Motor Power:580 kW Voltage (rms at VFD output and Motor terminal): 580 V DC Link Voltage: 900 V Cable length: 250 meter Filter: a Series Reactor at VFD Output PWM Peak Voltage at Motor Terminal: 1700 V (Twice the DC Link) PWM Rise Time at Motor Terminal: 0.2 us PWM Rise Time at Motor Terminal: 3-4 us According to the 1204-TFB2 datasheet, the maximum cable length should be less than 182.9 meters. Unfortunately, the length of the cable in our study case is about 250 meters. A series reactor has been installed at the VFD output, which increases PWM rise time and reduces the reflection phenomenon at the motor terminals. In other words, using a series reactor reduces the peak voltage at the motor terminal in comparison to when this reactor has not been installed at the VFD output. However, is it possible to use 1204-TFB2 in this case study (in this case study, cable length is more than 182.9 meter)? In other words, the limitation of the cable length can be increased by using a series reactor at the VFD output? [/INST] Hamed, The maximum length of 182.9m (600 ft) is correct as stated on page 94 of https://literature.rockwellautomation.com/idc/groups/literature/documents/in/drives-in001_-en-p.pdf Which drive are you working with? For our drives we have tables that provide the options for mitigating reflective wave issues. For example our 800 Hp PowerFlex 755 table 56 is on page 139 of the same manual I provided above. For cables over 250m you would need a reactor and a damping resistor and also a motor insulation rating of 1850V or more. You should not use a reactor with a motor terminator because it can cause voltage spikes exceeding the motor insulation ratings. This is documented in our Knowledgebase QA27120: https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/686116 Unfortunately, you cannot safely use a motor terminator at that cable length. \\n </s> |
<s>[INST] STO during deceleration EDIT: moved to Drives and Motion community -FL I have some servos on K5700 drives. The STO get broke with a light curtain block. This works fine during the move, the servo stops and restarts with an opto, but if the light curtain gets blocked during deceleration the drive keeps going and actually overshoots the target. Has anyone else seen this? There is no brake, but the servo is under load and should want to stop. [/INST] Hello Morley, couple of questions for you: What Kinetix 5700 are you using ERS3 or ERS4 ? Are you using a wired safety signal to the drive or a CIP Safety over EtherneIP ? When you operate an STO on a Servo drive you stop the motor control. So if you request a safety stop action that directly does an STO on the drive , the motor will coast without any control whatever the movement you were doing. This is called a stop category 0. So this is normal that you can overshoot a target since no more control is applied to the motor. With the Mechanical and load inertia the motor can rotate freely for a certain time if you don't have a safety brake. Now you can deploy a different safe stop category. Safe Stop category 1 , called also SS1 . Now the SS1 will give you time to decelerate correctly your axis and stop if before STO occurs. The way of deploying this feature will depend of the answers you will provide on the previous questions. you can also look at this manual : Kinetix 5700 Safe Monitor Functions Safety Reference Manual (rockwellautomation.com) (Link updated) regards \\n </s> |

<s>[INST] VFD DRIVE GV3000 /SE 230 - Analog Input Speed Control Issue I'm having problem with the speed control signal to the VFD drive Modle GV3000 / SE 230. It is an old model probably 12 to 13 years old. Orginally, a 0 to 20mA signal was used to control the speed of the motor through this VFD. But today the drive was not following the remote speed control signal, it just ran at minimum speed. Checked the parameters and jumper J4 and look correct. When a maximum signal is given i.e. 20mA the drive goes to the minimum speed (set by parmater P0003) and when a minimum signal is given the drive increase the frequency up to 15Hz (max speed is set at 60Hz). Re-wired the drive so a speed control signal from 0 to 10VDC volts was used as I thought the 4-20mA analog input signal receiver of the drive went bad. Jumper J4 was moved to pin 2-3 and the paramter P-0011 was changed to 2 (0 - 10 VDC). Still the same problem. When I increased the maxium speed paramter to a higher value, the drive will increase the speed accordingly when a minimum speed control signal is given. For example Speed Signal VFD Drive Speed Output In Hertz Max Speed In Hz set by P004 0 VDC 15 600 VDC 30 90 I would appreciate your feedback if you have ever encountered such a problem and were able to fix it.

I installed the connected components workbench 2.0 which gave me all of the above. Then I plugged the 1203 into my USB port, and installed the drivers that I downloaded from AB. After that, I setup the driver in RSLinx exactly to the instructions listed in the manual. When I go to RS Who, I get nothing for a drive. So I looked around and see there was a firmware update. So I updated to the 1.004 firmware using the hyperterminal method. That worked perfect. No errors. Tried again, and it still didn't work. I know I'm on Com 4, because when I go to control panel, it tells me so. I used hyper terminal to change the drive to a master instead of AUTO, and did a reset, and that didn't work. I have even went to the extreme of reinstalling windows, and trying different options in the OS... No firewall, etc... Nothing. IT did connect one time, and now I cannot figure out what it did to duplicate that. When I upgraded the firmware, I ran the controlflash install program which put a bunch of folders under 0001. Then in hyperterminal I selected 0001/0078/2500 and the boot one first, then the combo one second. I'm not sure what all the other folders are for. Is this correct? Any ideas?

Thanks in advance [/INST] Hi, Check your encoder cabling route, it must be far away enough from AC power cable. Check with OSC on your encoder square wave output , to ensure encoder can send correct output signal. Terence \\n </s> |

[/INST] https://rockwellautomation.custhelp.com/app/answers/detail/a_id/66014 This article explains the fan operation. Frames 0-4 The stirring fans sometimes referred to as muffin fans are on anytime the drive is powered up The main fans also known as the heatsink fans will turn on when the drive starts and turn off thirty seconds after the drive-stops. The turn off is independent of drive temperature. Frames 5, 6, 7 The stirring fans sometimes referred to as muffin fans are on anytime the drive is powered up. The main cooling fan(s) also known as heatsink fan(s) turn on when the drive starts and turns off thirty seconds after the drive-stops. The turn off is independent of the drive temperature Frames 8 and above The door mounted fans on the cabinet doors of an IP20 PowerFlex 755 drive frame 8 and greater turn on when the drive is powered, running, and is drawing more than approximately 10% of drive rated current. Document 454153 - PowerFlex 755 door mounted fans explains the operation of these fans in greater detail. On IP54 drives the door mounted fans are removed and a blower unit is installed on the top of the cabinet. This blower performs the same function as the door mounted fans and operates under the same criteria. The main cooling fan(s) also known as bridge fan(s) or heatsink fan(s) turn on when the drive becomes active (started) and turns off thirty seconds after the drive-stops. The turn off is independent of drive temperature. Note: The Fans for frames 2-7 are 24 Volt DC Fans. They can be tested by putting 24 VDC to the fans to see if they spin. Also, check that the connector outputs 24VDC if the drive is started. If not, replace power interface board (frame 6 and 7). If frame 5 and below, replace drive. The heatsink fan(s) for frame 8 and above is a self contained fan and inverter. \\n </s> |

If it's new to the I/O configuration, you'll have to update the Devicenet scanner in the rack. You can actually do this without putting the processor in PROG mode by putting the scanner in idle mode by turning off O.CommandRegister.Run bit of the scanner and then download to the module.

<s>[INST] Battery for Powerflex 753 755 real time clock Summary: Information about the battery for this function of the drive The Powerflex 753 and 755 have a clock on board that can be set to current time, but does not maintain it through a power cycle. There is provision to install a CR1220 battery on the main control board of each drive, but other than that, there is not much more about this feature.

<s>[INST] Continous Motion Control I have a system that uses Kinetix 6000 drives to control servo motors for positioning. I was wanting to know if there is a way to use a continous move command that will follow a setpoint from a feedback device.

Is there a way to do this? [/INST] Others have asked similar questions. Some options you can consider:- 1.Set the absolute posiiton of the servo to zero at its mid so that it can swing positive and negative (a home routine would be required on power up)Scale your PID output to correspond to absolute position.Every time your PID block is done - just execute an absolute MAM (just ensure you are't doing this too quick an update).Note - it doesn't matter if there's no new position to go to - if the servo is alreadt at the destination - it will go no where with a new absolute MAM to the same place. 2. If you want to do something with incremental moves instead, just periodically refresh an MAM instruction at a chosen rate again. \\n </s> |

<s>[INST] Looking for an AC Vector Drive Recommendation Hi, I am wondering if Rockwell has an AC vector drive that would meet the following requirements: (1) Power 220 VAC 3 phase (2) Capable of closed loop speed control using feedback in the form of a frequency (from and encoder or ring-kit w/ open-collector speed sensor). (3) Ability to display measured speed (from speed sensor) and to allow set point entry in scaled engineering units of my choice rather than Hz or even motor RPM. (This would be for a web handling machine, so I would like to be enter speed set points in ft/min and have actual speed also displayed in ft/min). This will require the drive to allow me to enter a scale factor to relate feedback from the speed sensor to ft/min taking into account my gear reductions, roll diameters, etc. (4) Allow set point entry using a built-in interface on the drive itself (keypad w/ LED display) rather than requiring the use of an HMI (5) Ability to follow a master speed reference that would be supplied to the drive as a frequency. Any advice will be greatly appreciated. Thanks in advance, Paul [/INST] Please explore TechNote 581453 \\n </s> |

<s>[INST] Powerflex 700 speed control, speed units RPM I have a couple of issues using ControlLogix to control the speed of a PF700 with parameter 79 (Speed Units) set to RPM. The desired speed is set from the PLC logic by assigning a value to the controller tag MyDrive: O.CommandedFreq. One might expect this value to be in RPM, but it isn't. By trial and error I find I need to multiply the desired speed in RPM by 13.654 before storing it in CommandedFreq. This gives a 'Commanded Speed' (parameter 2) in the drive which corresponds with the desired speed in RPM. Where does this scaling factor come from? I'm not getting a linear response from the motor in terms of the actual speed achieved. If I set CommandedFreq to 5000 then I get a Commanded Speed (P2) of 366.2RPM and a Speed Feedback (P25) of 366.2RPM - perfect. But a CommandedFreq of 10000 yields a Commanded Speed of 732.4 (perfect) but a Speed Feedback of 754.8. P23 Speed Reference always matches the Commanded Speed, but the motor is actually turning at the speed indicated by Speed Feedback. So the faster I ask it to go the more it overspeeds. Are there some drive parameters which need tweaking to address this? If anyone can point me at some relevant doc for this stuff that would be a great help. None of the manuals make any reference to the .CommandedFreq units being anything other than Hz (or implicitly RPM if Speed Units is RPM).

To avoid damage on the output of the 2nd sensor if the 1st one is active , you can use diodes. But I never test it. The other options are the following, use a PLC digital input to generate the Home input. but in this case you have to create you're own Homing cycle. Or use a time stamped input to create a Soft registration input (more complex to implement), the 2nd option is not as good as a real registration for very dynamic application. regards \\n </s> |
