Subchart A-2: Operation with Permanent Magnet Motors
Flowchart A-2 in Figure i.43 describes the setup procedure for running a PM motor in Open Loop Vector Control. PM motors
can be used for more energy-efficient operation in reduced or variable torque applications.
From
Flowchart
A
Input the motor data.
(T2-01 = 0)
Run the motor without load; check the rotation direction and
operation.Verify external signal commands to the drive work as desired.
Connect the load to the motor.
Run the machine and check for desired operation.

Powering Up the Drive
Review the following checklist before turning the power on.
Item to Check Description
Power supply voltage
200 V class: Three-phase 200 to 240 Vac 50/60 Hz
400 V class: Three-phase 380 to 480 Vac 50/60 Hz
Properly wire the power supply input terminals (R/L1, S/L2, T/L3).
Check for proper grounding of drive and motor.
Drive output terminals and
motor terminals
Properly wire drive output terminals U/T1, V/T2, and W/T3 with motor terminals U, V, and W.
Control circuit terminals Check control circuit terminal connections.
Drive control terminal status Open all control circuit terminals (off).
Status of the load and connected
machinery
Decouple the motor from the load.

A1-02: Control Method Selection
Selects the Control Method (also referred to as the control mode) that the drive uses to operate the motor. Parameter A1-02
determines the control mode for the motor.
Note: When changing control modes, all parameter settings depending upon the setting of A1-02 will be reset to the default.
