....Specifications differ according to the date assembled. Refer to page 346 to check the SERIAL number.
(1) Set the motor to be used
Refer to the following list and set the parameter according to the motor used.
Setting of the used motor selects the thermal characteristic appropriate for the motor.
Setting is required when using a constant-torque motor or IPM motor. Thermal characteristic of the electronic thermal
relay function suitable for the motor is set.
When General-purpose magnetic flux vector is selected, the motor constants (SF-JR, SF-HR, SF-JRCA, SF-HRCA,
etc.) necessary for control are selected as well.

REMARKS

When performing offline auto tuning, set any of "3, 13, 23, 43, 53" in
Pr. 71
.
(Refer to page 125 for offline auto tuning.)
 For the 5.5K and 7.5K, the Pr. 0 Torque boost and Pr. 12 DC injection brake operation voltage settings are automatically changed
according to the Pr. 71 setting as follows. (These are not automatically changed by the Pr.998 IPM parameter initialization setting.)
NOTE
 Set the electronic thermal relay function to the thermal characteristic for the constant-torque motor when using a
geared motor (GM-S, GM-D, GM-SY, GM-HY2 series) to perform General-purpose magnetic flux vector control.
