Technical Manual for EA350 Analog Pulse Type Servo Driver V101 Parameter functions: Set the time constant for high-frequency filtering of external pulse command input When the pulse setting position command is used, error may occur to the count of pulses received by the servo driver due to high-frequency disturbance resulted from various factors. Properly setting this parameter can avoid high-frequency disturbance. If the time constant for pulse input filtering is T f , and the minimum width of input signal is T min , then the input signal and the signal after filtering are shown in the following figure. Compared with the input signal, the signal after filtering is delayed for T f .
