Use IVMS control when a high torque is required for activation while you use SM/PMM motors.
Precautions for Correct Use
• If a high torque is necessary for activation, original IVMS control is used. If 03 is chosen for
the auto-tuning selection [HA-01], it can be detected whether the target motor can be driven
with the IVMS control, although combination check should be made in advance.
• The tuning with the IVMS control should be performed on an independent motor with the
Control mode selection, 1st-motor [AA121] set to 12 (SM/PMM: IVMS activation).
• In case of failure of the auto-tuning with the IVMS control, data necessary for the IVMS con-
trol cannot be obtained from the motor and the Control mode selection, 1st-motor [AA121]
should be set to 11 (SM/PMM: Synchronous activation) to drive the motor.
