REMARKS
When using a conventional motor (SF-VR, SF-JR) or other motors, refer to the
Instruction Manual (detailed).
<At-a-glance guide to setting the motor>
<When using other manufacturers’ motors>
Offline auto tuning (rotation mode) is necessary. Perform offline auto tuning with the motor alone before connecting
a load. If higher torque accuracy is required, perform online auto tuning next.

CAUTION
1. Set number of motor poles in Pr.81.
2. Make setting according to the motor used.
3. The half-tone screened cells are factory set.
4. Check the power supply specification of encoder and change a jumper connector.
5. *:Perform offline auto tuning (mode without rotation) for the wiring length to be reflected on the
control when exercising magnetic flux observer and the wiring length is long (30m or longer as
reference).
Offline auto tuning
The inverter measures necessary motor circuit constant and stores it to improve low speed
torque.
Online auto tuning
High torque accuracy corresponding to the motor temperature variation is available.
