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 = 61 [Motor 2 Select]. 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
[Decel Time 1] (high speed range) and C1-08 [Decel Time 4] (low speed range).
■
KEB Tuning
KEB Tuning automatically sets parameters used for the KEB Ride-Thru function and for the overvoltage
suppression function.
Control Tuning automatically sets these parameters in to the best values.
Parameters Automatically Set
C1-02 [Decel Time 1]
C1-08 [Decel Time 4]
C1-09 [Fast Stop Time]
L2-06 [KEB Decel Time]
L3-25 [Load Inertia Ratio]
*1 The drive automatically sets C1-08 [Decel Time 4] only when C1-11 [Ac/Dec Switch Frequency] ≠ 0.
*2 When L2-29 = 1 [KEB Method = Single KEB1 Ride-Thru], the drive will automatically adjust C1-09 [Fast Stop Time] and will not
adjust L2-06 [KEB Decel Time]. If you must not change the Fast Stop time, do not do KEB Tuning.
