Technical Manual for EA350 Analog Pulse Type Servo Driver V101 Parameter functions: Time constant for first-order low-pass filtering of acceleration torque The acceleration torque obtained through differentiation of the speed command contains a large quantity of high-order harmonic, and thus when it is added to the torque command, high-frequency vibration of the motor torque may be caused. Low-pass filtering of the acceleration torque before it is added to the torque command can remove high-frequency harmonic and reduce vibration. Parameter functions: When P4-04 speed loop differentiation is enabled, this parameter can limit the output value of the speed loop differentiation.
