 Driving a PM motor other than the MM-EFS or MM-THE4
Operating procedure
1.
Motor settings (Pr.9, Pr.71, Pr.80, Pr.81, Pr.83, and Pr.84) (Refer to
Set "8093 (IPM motor other than MM-EFS or MM-THE4) or 9093 (SPM motor)" in Pr.71 Applied motor. Set Pr.9
Rated motor current, Pr.80 Motor capacity, Pr.81 Number of motor poles, Pr.83 Rated motor voltage, and
Pr.84 Rated motor frequency according to the motor specifications.
2.
Performing the offline auto tuning for a PM motor (Pr.96) (Refer to
Set "1" (offline auto tuning without rotating motor (for other than MM-EFS or MM-THE4)) in Pr.96, and perform
tuning.
3.
Initial setting for the PM motor control using Pr.998 (Refer to
When the setting for the PM motor is selected in Pr.998 PM parameter initialization, the settings for PM motor
control is enabled. [PM] on the operation panel (FR-DU08) turns ON when PM parameter initialization is set.

4.
Parameter setting (acceleration/deceleration time, multi-speed setting, etc.)
Set parameters such as the acceleration/deceleration time and multi-speed setting as required.
5.
Operation command setting (Refer to
Select the start command and speed command.
6.
Perform the test operation.
NOTE
• To change to the PM motor control, perform PM parameter initialization at first. If the parameter initialization is performed after
setting other parameters, some of those parameters are initialized too. (Refer to
initialized.)
• Constant-speed operation cannot be performed in the low-speed range of 150 r/min or less.
• During PM motor control, the RUN signal is output about 100 ms after turning ON the start command (STF/STR). The delay
is due to the magnetic pole detection.
• During PM motor control, the function of the automatic restart after instantaneous power failure works only when an IPM motor
MM-EFS or MM-THE4 is connected.
When a regeneration unit is used, the frequency search may not be available if the rotation speed is about 10% higher than
the rated speed.
