5.2 b: Application

b9-01: Zero Servo Gain
Parameter b9-01 adjusts the responsiveness of the Zero Servo position loop. Increase the value if the response is too slow
and the deviation from the zero position rises too high when load is applied. Decrease the value if vibrations occur during
Zero Servo operation.
Note: Before adjusting the Zero Servo gain, make sure the ASR parameters (C5-) are set up properly and vibration or hunting does
not occur when running with a zero speed reference.
No.
b9-01

b9-02: Zero Servo Completion Width
Sets the output range of the Zero Servo completion signal. Enter the amount of deviation allowable from the desired
position to trigger Zero Servo. An output terminal set for Zero Servo (H2- = 33) will be triggered when the motor
reaches the position Zero Servo position plus or minus b9-02.
No.
