Hello all, I am not sure if it is the same problem, but i commissionned 4 drives on a site, 2 Frame C and 2 Frame D. Everything went fine on the Frame D ones. However, on the drive C ones, the fan kept going on and off spuriously with variable times for the ON and OFF(like On for 2 sec, OFF for 10 sec, ON for 5 sec, OFF for 1 sec, ON for 10 sec, OFF for 2 sec, and so on...) . While this is happening, no ON command was sent to the drive, and the two LEDs on the front show "Ready to start" status. Is it possible to know what could be the reason for this to happen? The frame C and frame D ones have almost same wiring for command and feedback) Thanks in advance Best regards Philippe Kfoury Siemens Canada
