7.3.4 Analog Input Filter
When analog input is used, there might be external interferences that affect the accuracy of the analog
input voltage. In some cases will cause the motor to turn unexpectedly, or unstable torque output.
Therefore, analog input filter is recommended. It is designed as a digital low pass filter; reasonable filter
frequency can significantly improve the motor performance.
To setup the analog input filter directly from the drive, please refer to the following calculation
