How to wire the power to switch the rotation direction of a motor attached to the DD series torque detector.

To change the rotation direction, switch the 2 of 3 phases (200 V) of the motor attached to the DD series torque detector. Please refer to the following wire connection method.

 

Wire connection method

 

Attached motor specification

 

Model name Power source Number of polarity Electricity consumption (VA)
DD-503, 104, 204 AC200V 3-phase 4-pole 25
DD-504
DD-505, 106, 206 50
DD-1506B, 1107B, 1207B
DD-507 140
DD-108

 

Caution

Please set the belt rotation direction of the motor reverse to the shaft rotating direction.

Please set the contact amount of the switching circuit or the wire rod of the cable to 5 times or more of the motor rated value with a consideration of a rush current of the motor.

* AC220V is option.

 

Remove the motor cover and see the rotation direction of the motor belt to check the direction by visual contact.

 

Belt rotation direction (as viewed from "Drive Side" nameplate)

 

The shaft is rotating CW (Clockwise), belt rotation direction is CCW … Drive CW

The shaft is rotating CCW (Counterclockwise), belt rotation direction is CW … Drive CCW

Switch the power circuit to rotate as above. Also, use the attached cable (5 m) for the cover cable of the detector. Please judge the rotating direction in view of "Drive Side" seal so as not to make a mistake.

 

 

Caution:

Do not touch the belt when you remove the cover. There is danger being rolled in the machine.
