Did anyone ever solve the issue aboveI? I am have the same problem which is the drive Powerflex 40 no longer will supply power to the 22 comm E card. The drive will work fine if the control is hard wired. Sometimes both the 22 comm E and the drive fail but most of the time its just the drive power output to the card
Drive layout, Powerflex 40 with a 22 comm E card and Ethernet attached 2to 3 Powerflex 4 slaved to the Powerflex 40 via 485 network.
I am presently replacing the Powerflex 40 drives with the new 525 drive and have had no issues but this can be very costly when you have over 200 drives! Not to mention the install time of remapping all the Tags related to the drives and not just at the PLC but the HMI as well.
