Mitsubishi Electric FR-A820-00046 (0.4K) Instruction Manual page 518

NOTE
• If "9999" is set, tuning data will be invalid and the constant values for Mitsubishi Electric motors (SF-PR, SF-JR, SF-HR, SF-
JRCA, SF-HRCA and SF-V5RU (1500 r/min series) and so on) are used.
 Changing the motor constants (when setting motor constants in the
internal data of the inverter)
• Set Pr.71 as follows.
Mitsubishi Electric standard motor
Mitsubishi Electric high-efficiency motor
Mitsubishi Electric constant-torque motor
Mitsubishi Electric high-performance
energy-saving motor
Vector control dedicated motor
Other manufacturer's standard motor
Other manufacturer's constant-torque
motor
• Set desired values as the motor constant parameters. The display units of the read motor constants can be changed with
Pr.684 Tuning data unit switchover. Setting Pr.684 = "1" disables parameter setting changes.

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.
