14.11.16.3 Speed deviation monitoring
Overview
The function calculates and monitors the speed or velocity of a machine component.
Description of function
The converter compares speed r0586 with speed actual value r2169 and signals when the
di󹪜erence between the encoder signal and the motor speed is too high.
