Error description 231-C640
Error message
C640 PIC switching not possible in %1
Cause of error
- The nominal value(S in inverter.inv) changed
- after DSP start, or
- after the current controller adjustment is started, or
- after the readiness of the power module is switched.
Error correction
- Check the LT entry (configuration datum ampName) in the machine configuration
- Check the nominal value of the PICS (the S column in in inverter.inv)
- If necessary, change the PWM frequency (to >= 5 kHz)
- If necessary, replace the power module
