7.3.4 Analog Input Filter
When the analog input is used, there can be external signal interference that will affect the accuracy of
the analog input voltage. In some cases will cause the motor to turn unexpectedly, or cause unstable
torque output. Therefore, use of the analog input filter is recommended. The filter is designed as a digital
low pass filter; a proper filter frequency setting can significantly improve the motor’s performance.
When viewing or setting this value on the drive’s control panel, refer to the following calculation:
