Technical Manual for EA350 Analog Pulse Type Servo Driver V101 Parameter functions: When this parameter is set to 0, it means an IP controller is used; when it is set to 100, it means a PI controller is used; when it ranges between 1~99, it means a PDFF controller is used. When an IP controller is used, the motor speed will have no or little overshooting, but the response is slow. When a PI controller is used, the motor speed will overshoot, but the response is quick. The PDFF controller has combined features of the IP and PI controllers to reduce overshooting and improve system response. When the parameter approaches closer to 0, it means the IP action is growing stronger, vice versa.
Parameter functions: This parameter is only valid when P4-00≠0, i.e. the gain is in the automatic adjustment mode 1, 2, 3 or 4. It is used when P4-01 cannot be set higher to improve the speed loop gain. Specifically: Speed loop gain = P4-03 P4-13 In the automatic adjustment mode, decreasing the set value can improve the response of the servo in low rigidity scenarios. However, if the value is set too small, vibration may be caused 157 P4-13 Rigidity adjustment coefficient Initial value 0.5 Communication address 040DH Unit - Time of taking effect With immediate effect Setting range 0.5~1.0 Data size 16bit Control mode P S
