P12
Motor 1 (rated slip frequency)
P12 specifies rated slip frequency. Obtain the appropriate values from the test report of the motor or by calling the
manufacturer of the motor. Performing auto-tuning automatically sets these parameters.
• Rated slip frequency: Convert the value obtained from the motor manufacturer to Hz using the following
expression and enter the converted value.
(Note: The motor rated value on the nameplate sometimes shows a larger value.)

P13
Motor 1 (iron loss factor 1)
The combination of P99 (Motor 1 selection) and P02 (Motor 1 rated capacity) data determines the standard value.
Basically, there is no need to modify the setting.
P16 to P20
Motor 1 (Magnetic saturation factors 1 to 5)
The combination of P99 (Motor 1 selection) and P02 (Motor 1 rated capacity) data determines the standard value.
Performing auto-tuning while the motor is rotating (P04 = 2) sets the value of these factors automatically.
