4.9.2

Applied motor (Pr.71)

Set the applied motor type.
When the S-PM geared motor is used, the motor type is automatically set by PM parameter initialization.

........Specifications differ according to the date assembled. Refer to page 294 to check the SERIAL number.
NOTE
 When the applied motor is not S-PM geared motor offline auto tuning is required by setting Pr.96 Auto tuning setting/
status. (For the details on offline auto tuning, Refer to page 105.)

When the S-PM geared motor is not used, offline auto tuning is required.
• What is offline auto tuning?
This function simplifies setting of parameters for driving PM motors. The motor constants used for operation under
PM sensorless vector control are measured automatically. (Some motors cannot be driven with the result of offline
auto tuning.)
