Yaskawa AC Servo Motor 1300RMP 850W 7.1A SGMG-09V-2A-V631 New in box

1. Disconnect the main power to the HVAC system.

2. Disconnect the High Voltage SIGNAL connection(s) from the motor to the HVAC system.

3. Reconnect the main power to the HVAC system. Confirm there is proper voltage to the High Voltage POWER connections on the motor.

4. Energize any of the Low Voltage SIGNAL (speed) tap selections continuously for a minimum of 5 minutes.

5. Disconnect the main power to the HVAC system for a minimum of 1 minute. Confirm there is no voltage to the High Voltage POWER connections on the motor. During this time reconnect the High Voltage SIGNAL connection(s).

Now the Rotation Sensing feature will operate as described on page 23 “Rotation Sensing”. If the motor does not perform the Rotation Sensing feature, repeat this procedure carefully and confirm all timings with a watch.

If the motor again selects the wrong direction, confirm that the selected Evergreen IM is not too large for the system. See the selection chart on page 30. If the motor has not been sized properly, replace the motor.
