Parameter 20-33 is used when 20-07 is set to 0 and frequency command source is set to analog input mode.
Analog input signal, owing to the noise, will cause the system to determine the operation does not reach the
constant speed so the problem may occur. Thus, adjust parameter 20-33 to avoid this situation occurring..
The following figure an overview of the automatic speed regulator (ASR) block.
V/F + PG control mode:
The ASR function adjusts the output frequency to control the motor speed to minimize the difference between the
frequency reference and actual motor speed.

If one of the multi-function input (03-00 to 03-07) is set to 42 (PG is disabled), the input can be used to enable or
disable the speed control loop system (ASR).
