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

Parameter
Description
p2192
Load monitoring delay time
(factory setting 10 s)
After the motor is switched on, if the "LOW" signal is present at the associated
digital input for longer than this time, the inverter signals a load failure (F07936).
