ASR and Inertia Tuning

To increase drive responsiveness and prevent hunting, use Auto-Tuning to automatically adjust the control-related
parameters.
These types of Auto-Tuning are available for the control system:
• Deceleration Rate Tuning
• KEB Tuning
Note:
If you do Control Tuning, you cannot set H1-xx = 16 [Motor 2 Selection]. Do not do Control Tuning for applications that switch between
motor 1 and motor 2.

Deceleration Rate Tuning
Deceleration Rate Tuning automatically sets the deceleration rate to prevent an ov [Overvoltage] fault during motor
deceleration. Set C1-11 [Accel/Decel Time Switchover Freq] first to automatically set parameters C1-02
[Deceleration Time 1] (high speed range) and C1-08 [Deceleration Time 4] (low speed range).

Application Conditions and Benefits
• Applicable when driving an induction motor or a PM motor
• Suitable for derating torque applications, for example fans and
pumps.
• After Auto-Tuning, the wiring distance between the drive and
motor changed by 50 m or more.
• When the motor output and drive capacity are different.
