5 DRIVING THE MOTOR
The inverter needs frequency command and start command.
Frequency command (set frequency) determines the rotation speed of the motor.
Turning ON the start command starts the motor to rotate.
REMARKS
Set the required parameters according to the load and operating
conditions. (Refer to page 32.)
