During the process of auto tuning, the following
parameter will be automatically set.
• Speed Loop Proportional Gain (SEt-02)
• Speed Loop Integral Gain (SEt-03)
• Position Loop Proportional Gain (SEt-04)
• Torque Command Filter (SEt-06)
• Speed Command Filter (SEt-40)
• System Gain (SEt-42)
• Inertia Ratio (SEt-66)
If auto tuning doesn’t work well, please adjust the gain according to
the command below.
1. First, set the speed integral gain (SEt-03) to its default value.
2. Raise the speed proportional gain (SEt-02) to the range that doesn’t cause
vibration in the system.
3. Raise the speed integral gain (SEt-03) to the range that doesn’t cause
vibration in the system.
4. Try jog operation or pilot operation.
5. If there is a serious vibration or noise, please reduce the speed
proportional (SEt-02) or speed integral gain (SEt-03).
Please repeat the fourth and fifth steps until stabilization.
Quick response cannot be expected when the inertia of the load
exceeds five times the inertia of the motor’s rotor or when the load
torque is higher than the motor torque. In these cases, please follow
the command below for adjustment.
• Reduce the inertia of the system and load torque.
• Extend the time for acceleration and deceleration.
• Replace the motor with another one with higher rotor inertia.
• Use a motor with higher output torque.
• Lower the gain to reduce the response of the system.
