Step3 Check motor rotation without load.
z
Press RUN Key. 7-segment Display will indicates 00.0to 05.0. Such value is the frequency
output value.
z
Check the operation direction of the motor.
IF the direction of the motor is incorrect:
Press STOP Key, turn off the AC power supply. After Power indicator LED is off,
change over theT1 and T2.
Supply the power again, then check the motor direction.
