Control 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:
• Inertia Tuning
• ASR Tuning
• 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.
Application Conditions and
Mode T3-00
• For Feed Forward Control
• When L2-29 = 1 [Kinetic Energy
Backup Method = Single Drive KEB
Inertia Tuning 0
Ride-Thru 2].
• When MFDI H1-xx = 7A [KEB Ride-
Thru 2 Activate (N.C.)].
To let the set response frequency
ASR Tuning 1 (including Inertia Tuning) automatically
adjust the ASR gain.

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.
