Inverter diagnostics
The following parameters supply some information about the current operating status of the inverter.
This includes the following information:
–
Active access protection after log-in by means of PIN1/PIN2
–
Currently loaded parameter settings
–
Cause(s) for disable, quick stop and stop
–
Active control source and active setpoint source
–
Active operating mode
–
Status of the internal motor control
–
Keypad status
Some of the following parameters contain bit-coded status words. Each single bit has a certain meaning.
