Parameterizing the monitoring functions
Description
Current limit for no-load detection
If the frequency inverter current is below this value, the message "no load" is output.
Delay time for the "no load" message
Delay time for the "motor locked" message
Delay time for the "motor stalled" message
Deviation of the setpoint from the actual value of the motor flux as of which the
"motor stalled" message is generated
This parameter is only evaluated as part of encoderless vector control.
