Speed deviation monitoring
The inverter calculates and monitors the speed or velocity of a machine component.
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 an electronic encoder for the "Speed monitoring" function, e.g. a proximity
switch. The inverter analyzes an encoder signal at max. 32 kHz.
To use the function, you must connect the encoder to one of the digital inputs DI 1 or DI 2
and connect the relevant digital input with the function in the inverter.
