Switching to PM Motor Mode

To use PM motor control, you need to switch the inverter to the PM motor mode.
Follow the steps below to switch to the PM motor mode:
(1) Set the Inverter Mode Selection (b171) to 03 (PM motor).
(2) Set the Initialization Execution (b180) to 01 (Execute initialization), then press the
Enter key. Parameter initialization starts.
(3) When parameter initialization is in progress,
nately.
(4) When the initialization process is completed,
inverter was switched to the PM control mode.
Precautions for Correct Use
• If b171 is set to other than 00, regardless of the settings in Initialization Selection (b084) and
Initialization Target Setting (b094), when initialization is executed with the Initialization Exe-
cution (b180) set to 01 (Execute initialization), all data (set data, fault monitor data, and
DriveProgramming data) are initialized.
However, the following parameters are not initialized: Total RUN Time Monitor (d016), Total
Power ON Time Monitor (d017), Heavy Load/Light Load Selection (b049), Initialization Data
Selection (b085), Initialization Target Setting (b094), FV/FI Adjustment (C081/C082), Therm-
istor Adjustment (C085), and Position Data at Power Off (P082).
• To return to the induction motor mode after switching to the PM motor mode, set b171 to 01
(Induction motor), then execute initialization with b180 set to 01. The inverter switches to the
induction motor mode while displaying "I-C" on the Digital Operator.
Parameter No.

Offline Auto-tuning for PM Motor Parameters

Offline auto-tuning for PM motor parameters consists of the following four steps:
• Presetting of parameters
• Auto-tuning
• Operations after auto-tuning
• Operations in case of error

Presetting of parameters
(1) Set the PM Motor Capacity (H103) and the PM Motor Pole Number (H104) according
to your PM motor.
