6-8-3 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 mode).
(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, and are displayed
alternately.
(4) When the initialization process is completed, appears, meaning that the
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 parameters Total RUN Time Monitor (d016), Total Power ON Time Monitor
(d017), and Initialization Data Selection (b085) will not be initialized.
• To return to the induction motor mode after switching to the PM motor mode, set b171 to 01
(Induction motor mode), then execute initialization with b180 set to 01. The inverter switches
to the induction motor mode while displaying “I-C” on the Digital Operator.
