Load monitoring

The load monitoring comprises the following components:
● Load failure monitoring
● Monitoring for torque deviation
● Speed deviation monitoring
If the load monitoring detects a load failure, the inverter issues fault F07936. For a torque
and speed deviation, as response, you can either set an alarm or a fault. Details are
provided in the following descriptions.

Load failure monitoring
Principle of operation
Using this function, the inverter monitors the speed or velocity of a machine component. The
inverter evaluates whether an encoder signal is present. If the encoder signal fails for a time
that can be adjusted, then the inverter signals a fault.
Examples of how the function can be used:
● Gearbox monitoring for traction drives and hoisting gear
● Drive belt monitoring for fans and conveyor belts
● Blocking protection for pumps and conveyor belts
