Speed deviation monitoring
Using this function, the inverter calculates and monitors the speed or velocity of a machine
component. The inverter analyzes an encoder signal, calculates a speed from the signal,
compares it to the motor speed and reports any excessive deviation between the encoder
signal and the motor speed.
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 conveyor belts
You require a transmitter for this function, e.g. a proximity switch. The inverter analyzes an
encoder signal at max. 32 kHz.
