Hello Dear all,

I used a PLC s7 300 CPU315-2 DP configured with many DC Drives (6RA70) via Profibus. The problem is that on one of the drives it often appears flashing the A083 alarm and then disappears again. Simultaneously with the flashing of the A083 alarm, there are also fault indications in the PLC, the SF LED is constantly on and the BF LED is flashing, And then both of them are also off again.

Please advise me, is this problem with the PLC or the drive? and how to solve it?
