Hi Everyone, I have a PowerFlex 525, in Velocity Mode with a Encoder Card "25-ENC-1". We are controlling this drive via TCP/IP with a 1769-L32. Through the PLC if I try to toggle the Bit for "Pos Redefine" in A560 [Enh Control Word] it instantly turns back to 0. But through the Parameter List Editor I am able to toggle A560. For My function I need to have the drive in Velocity Mode, If I change the drive to Position Mode I am able to toggle "Pos Redefine"   Any Thoughts would be great      

Hello. I have a 1756-L72S with a 1756-EN2T and an ethernet network of point I/O and three Powerflex 755's.  I'm having trouble with the Powerflex 755.  Only one of them shows up as "running" status, the other two have this status in the status field of RSLogix/Designer.   All 3 drives are the same, and as far as I know, they have the same setup.  On all three drives, I physically entered the IP address on the HIM module.  Then I added the three drives to the Ethernet device tree in the same way (with the exception of different IP addresses of course).  I can ping all 3 drives. The only thing I can think to mention is that the all three drives have firmware version 12.001, and the PLC (v20.13) only has firmware version 9 selection for the 755 drives.  I'm surprised even one of them showed up as connected, so that's a little strange to me.  I would've thought with electronic keying set to "compatible" I would need to down grade the drive firmware.  But in any case, one of the drives seem to be running status, so I didn't think this version mismatch would cause the error I'm seeing.      

Dear all, i would like to stop my system in emergency case, it should be stop immediately. my drive is power flex 755 and communicate with PLC control logix via ethernet (port 13). So in control word from PLC to drive, i see a bit is "current limit stop". what does it mean, what kind of stop? can i use it to stop my system (moving item is too heavy, near 200kg)? Thanks in advance,

Good day, I´m helping with small project and currently i am stuck because of this problem. And I hope you can help me out. I´m using PowerFlex 525 connected with AB CompactLogix 1769-33ER PLC via EtherNet/IP. Connection is working, I can read and write values from/to 525. To configure both devices i´m using RSLogix 5000. 1) First problem occurs after I loaded configuration to 525 and it´s, that 525 keeps overwriting values of Accel and Decel Time 1. It happens when i directly change parameters in Module Properties (online) or after I upload configuration to device. It happens even if i set parameters directly to 525 with its HMI panel. - I kinda get around this problem when i use Accel/Decel Time 2 for Step logic, but if i send direct reference value motor still jump to it and that is not good, especially when changing direction of rotation. 2) Second problem is that I cant get Speed Sources and Start References right. Usually Is working only option 1 and others are not, or they are doing something else that they should. For better imagination this is what i want to do: I have 3-state switch (left = 1 ON(DigIn TrmBlk 02), 2 OFF; center = 1 OFF, 2 OFF; right = 1 OFF, 2 ON(DigIn TrmBlk 03)), In center position I want to control 525 with EtherNet (already working when: Start 1 AND Speed 1 = EtherNet/IP). In left position I want to control motor directly with Drive Pot and In left position a want to start Step Logic (which i have already set) - Funny thing, If I set Start 1 = Ethernet, Speed 1 = Step, Start 2,3 = DigIn, Speed 2,3 = Drive Pot then in all three position motor goes in Step logic.. Or when i get left and right position working then Ethernet is blocked.. and this kind of things.. I Attach print-screen of my current settings, if you need something more just, tell me. Thank you for your time, and I hope someone will be able to help me.

Hello everybody, I am connecting my DCS digital output (115VAC) to AB PowerFlex 753 Digital Input. We are using the 20-750-2262D-2R I/O option in the powerflex which is 115VAC I/O with 2 Analog In, 2 Analog Out, 6 Digital In and 2 Relay Outputs. My question is, what is the current or power consumption of the PowerFlex DIs at 115VAC. I need to specify the right fuse size for my digital output. Thanks,
