6. DISPLAY AND OPERATION

6.8.4 Motor-less operation

Without connecting the servo motor, you can provide output signals or monitor the status display as if the

servo motor is running in response to external input signals. This operation can be used to check the

sequence of a host programmable controller or the like.

(1) Operation

After turning off the signal across SON-SG, choose motor-less operation. After that, perform external

operation as in ordinary operation.

(2) Status display

You can confirm the servo status during motor-less operation.

Pressing the "MODE" button in the motor-less operation-ready status calls the status display screen.

With this screen being shown, perform motor-less operation. Every time you press the "MODE" button,

the next status display screen appears, and on completion of a screen cycle, pressing that button

returns to the motor-less operation-ready status screen. For full information of the status display,

refer to Section 6.2. In the test operation mode, you cannot use the "UP" and "DOWN" buttons to

change the status display screen from one to another.

(3) Termination of motor-less operation

To terminate the motor-less operation, switch power off.
