I had a similar problem with S120 drive 6SL3320-1TE32-6AA3 with firmware 4.8 installed on 2018 The motor module fan does not run even if the voltage was correctly detected on connection plug inside the drive measured by instrument Sometime when you completely switch off and on the drive the fan restart without problem We found that some time the parameter P1800 Pulse frequency set point of the drive is related to the issue I mean that parameter change the PWM inside the drive Could it generate some kind of noise to the fan and does not allow the running even if the voltage is present ? Could be a defective stock of fan produced on 2018? Regards, Luca ------------------------------------------------------------------------------------------ |
