9-2-2 Resolver
Take the following steps to inspect the resolver:
1. Make sure the controller is in READY condition and not able to get a START signal from the PLC.
(Supply STOP signal only)
2. By the “ ◄ “ or “ ► ” pushbutton to make the bottom left side of the display show "Non" (Mon).
3. By the “ ▲ ” or “ ▼ ” pushbutton to make the bottom right side of the display show "3". (Angle
Rotation Display).
4. Check following. If the socket of the tool is turned in the clockwise direction, the angle
indication should increase. If the socket of the tool is turned in the counter clockwise direction,
the angle indication should decrease. Verify that the angle rotated matches the indicated angle
in the data display.
9-2-3 Motor Windings and Resolver Windings
To check the motor or resolver windings, measure the winding's resistance and the isolation
resistance.
Perform measurement of the resistance value after turning off the power
to the Unit and the tool device/equipment.
1. Disconnect the motor connector from the tool assembly.
2. Measure the resistance between windings. Check that the resistance is within ±10%
of the specified value..
3. Measure the isolation resistance between each pair and the frame.
