Error description 231-8320
Error message
8320 PIC: Actual value does not equal the nominal value %1
Cause of error
Possible cause:
The measurement range of current of the inverter is not set to the range specified in the configuration.
This message can appear, for example, if a new CC controller unit has been installed or there was an unexpected change to the configuration.
"PIC" designates a microcontroller inside the inverter that switches and reads back the measurement range of current.
- Nominal value (value in column S of the power module table) = 1, however:
- There is no PIC
- PIC can't be switched
- Access to PIC is deactivated (machine parameter motEncCheckOff, Bit16=1)
- Nominal value (value in column S of the power module table) = 0, however:
- Access to PIC is deactivated (machine parameter motEncCheckOff, Bit16=1) and PIC was already switched to 1
Error correction
- Check the power module entered in the machine configuration
- Check the nominal value of the PIC (value in column S of the power module table)
- Perhaps change the PWM frequency (to >= 5 kHz)
- Perhaps exchange the power module
