Heavy load monitoring
If the apparent current of the motor exceeds a defined threshold value due to a heavy duty state, a configurable error is triggered (incl. logbook entry).
Conditions
Monitoring is activated as soon as the motor is running. Monitoring can be deactivated with the setting "No response".
Details
Exceedance of the defined threshold:
–
If the actual apparent current exceeds the configured threshold value, the delay time encoder is started.
–
If the actual apparent motor current falls below the threshold value minus 5 % (hysteresis - not adjustable), the delay time encoder is set to zero.
Independent of the error response, the output signal (Heavy duty monitoring [84]) is triggered:
–
If the actual apparent current of the motor exceeds the threshold for longer than the delay time, the output signal is set to TRUE.
–
If the actual apparent current of the motor falls below the threshold value minus 5 % (hysteresis), the output signal is set to FALSE.
–
If the delay time is set to 0 seconds, the output signal is immediately set to TRUE.
The error response is activated according to its settings:
–
If the actual apparent current of the motor exceeds the threshold value for longer than the configured delay time, the selected error response is activated.
–
When the error response is triggered, an entry is generated in the logbook (exception: Error response - Selection [0]): "Motor overload" (error code 65337 | 0xFF39)
