◆ 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
T3-00 = 2
To automatically adjust the deceleration rate to
prevent an ov [Overvoltage] fault.

KEB Tuning T3-00 = 3
• To automatically adjust parameter settings to
prevent an ov [Overvoltage] fault with the KEB
Ride-Thru function.
• When L3-11 = 1 [Overvolt Supression Select =
Enabled].

■ 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.

*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.
