KE - Differential Filter
Compatibility: Servo drives only
Affects:
Servo tuning and performance
Sets or requests the differential control parameter filter frequency. The filter is a simple one-pole, low-pass filter
intended for attenuating high frequency oscillations. The value is a constant that must be calculated from the
desired roll off frequency. See equation below.
C = 72090 / (1400/F + 2.2)
where C = Filter Value, K = desired filter Frequency in Hz
NOTE: It is recommended to use the Quick Tuner software for tuning and configuring your servo system.
