A
B
In AutoMode (PI), the value “B” indicates the responsiveness setting. When the setting value is higher, the
responsiveness is faster.
Adjust P2-31: Increase the setting value of P2-31. Increase the value “B” to speed the responsiveness or
reduce the noise.
Adjust P2-25: According to the setting value of P2-31 speed and adjust the responsiveness.
Continuously adjust until the satisfactory performance is achieved, and then the tuning is completed.
YES
1. Increase P2-31 value B to reduce noise and
refer to Table 5.B to set P2-25.
2. If the user do not want to decrease the
value of P2-31 value B, the user can adjust
P2-23 and P2-24 to suppress the resonance
of mechanical system.
If there is
resonance noise ?
Servo off, and then Servo on
after setting P2-32 to 2.
When P0-02 is set to 14, the display will show the ratio of
Load inertia to Motor inertia (J_load / J_motor)
The satisfactory
performance is achieved.

If the change of (J_load / J_motor) is not
great, Servo off, and then set P2-32 to 3.
Servo drive receive FWD. and REV. and Accel. and Decel.
