◆ 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.
