Operations in case of error
If auto-tuning is aborted due to an error, review the preset parameters according to "1. Presetting
of parameters" and check that the rated torque of the motor is at least 50% of the rated output cur-
rent of the inverter. If the inverter is connected with any load, disconnect it and retry auto-tuning.
If the error persists or auto-tuning is still aborted, enter the motor parameter values directly.
For details, refer to 6-8-5 PM Motor Parameter Settings on page 6-62.
Precautions for Correct Use
• If a trip occurs during auto-tuning, the auto-tuning process will be forcibly ended. In this case,
the inverter displays a trip display in preference to the abort display. Refer to 10-1-2 Alarm
Code List on page 10-4.
• If the auto-tuning process is not ended, press the STOP/RESET key. This causes the pro-
cess to be forcibly ended. Then, review the preset parameters according to "1. Presetting of
parameters" and retry it.
• If the auto-tuning process is aborted, or if you interrupt the process by pressing the
STOP/RESET key or by turning OFF the RUN command, the auto-tuning settings may be left
in the parameters H111 to H113.

PM Motor Parameter Settings

To use PM motor control, you need to set motor parameters.
Normally, you perform offline auto-tuning to set motor parameters.
However, if the offline auto-tuning process is aborted, for example, when the inverter does not reach
50% of the rated current during auto-tuning, set the motor parameters manually.
• Set the PM Motor Parameter Selection (H102) to 00 (Standard PM motor parameter).
• Set the parameters listed below according to the motor parameters for your PM motor.
• Obtain the motor's datasheet from the PM motor manufacturer and set each motor parameter.
For H106 to H109, set the value of the motor with the wiring for one phase in Y-connection (that is,
50% of the phase-to-phase value of the motor).
⚫ PM Motor Capacity and PM Motor Pole Number (H103 and H104)
Set the capacity and number of poles of your PM motor.
⚫ 1st Base Frequency and 1st Maximum Frequency (A003 and A004)
Set the rated frequency and maximum frequency of your PM motor.
The rated/maximum frequency values can be calculated from the rated/maximum rotation speed of
the PM motor as follows:
Rated frequency
(Maximum frequency) [Hz]
⚫ 1st Motor Rated Voltage Selection (A082)
Set the highest value closest to the rated voltage of your motor.
⚫ PM Motor Rated Current (H105)
Set the rated current of your PM motor.
In addition, for the purpose of overload protection, set the rated current of the PM motor in the 1st
Electronic Thermal Level (b012).
