Technical Manual for EA350 Analog Pulse Type Servo Driver V101 Parameter functions: Sets the time constant of hybrid vibration suppression for fully closed-loop control. In case of fully closed-loop control, please increase the setting value gradually and check changes in the response. If the rigidity of the transmission mechanism between the full closed loop and the inner loop is insufficient, you can specify an appropriate time constant to improve system stability, i.e. being able to secure inner loop effect in transient state and fully closed loop in steady state. This can be ignored in case of sufficient rigidity. Caution ☞ 1. This parameter will affect system response.
A greater value gives rise to slower system performance. Use it in case of oscillation arising from insufficient rigidity of the transmission shaft between the external encoder and the servo motor. Parameter functions: Sets the time constant of hybrid vibration suppression for fully closed-loop control. PC-08=0 : Do not detect external encoder disconnection. PC-08=1 : Detect external encoder disconnection. Caution ☞ Detection of external encoder disconnection can’t be guaranteed.
