9999
Uses the constant value of Mitsubishi motor
(SF-PR, SF-JR, SF-HR, SF-JRCA, SF-HRCA and
so on).
NOTES The function is enabled under Advanced magnetic flux vector control.
Even if a motor other than Mitsubishi standard motors (SF-JR 0.4 kW or higher), high-efficiency
motors (SF-HR 0.4 kW or higher), Mitsubishi constant-torque motors (SF-JRCA 4P, SF-HRCA 0.4 kW
to 55 kW), or Mitsubishi high-performance energy-serving motor (SF-PR), such as other manufac-
turers' induction motors, SF-JRC, SF-TH, etc., is used, or when the wiring length is long (approx. 30
m or longer), a motor can run with the optimum operation characteristics by using the offline auto
tuning function.
Tuning is enabled even when a load is connected to the motor.
During offline auto tuning, the motor rotation can be locked (Pr. 96 = "1") or unlocked (Pr. 96 =
"101"). The tuning is more accurate when the motor can rotate (unlocked).
Reading/writing of the motor constants tuned by offline auto tuning are enabled. The offline auto
tuning data (motor constants) can be copied to another inverter with the operation panel.
The offline auto tuning status can be monitored with the operation panel and the parameter unit.
