 Changing the motor constants (when setting motor constants in the
internal data of the inverter)
• Set Pr.71 as follows.
• 200/400 V class
Mitsubishi Electric high-performance energy-saving

Mitsubishi Electric geared motor
Mitsubishi Electric inverter-driven geared motor for
encoder feedback control
Mitsubishi Electric standard efficiency motor
Mitsubishi Electric high-efficiency motor
Mitsubishi Electric constant-torque motor
Other manufacturer's standard motor
Other manufacturer's constant-torque motor
• 575 V class
Vector control dedicated motor

NOTE
• As the motor constants measured in the offline auto tuning have been converted into internal data (****), refer to the following
setting example when making setting. (The value displayed has been converted into a value for internal use. Therefore, simple
addition of a value to the displayed value does not bring the desired effect.)
Setting example: To slightly increase the Pr.90 value (5%)
When "2516" is displayed for Pr.90, set 2642 (2516 × 1.05 = 2641.8) in Pr.90.
• If "9999" is set in the motor constant parameters, tuning data will be invalid and the constant values for Mitsubishi Electric
motors (SF-PR, SF-PR-SC, SF-JR, SF-HR, SF-JRCA, SF-HRCA, SF-V5RU (1500 r/min series), GM-[], GM-DZ, or GM-DP)
are used.
