6. DISPLAY AND OPERATION

6.7 Output signal forced output (DO forced output)

POINT

When the servo system is used in a vertical lift application, turning on the electromagnetic brake interlock signal after assigning it to pin CN1B-19 will release the electromagnetic brake, causing a drop. Take drop preventive measures on the machine side.

The output signal can be forced on/off independently of the servo status. This function is used for output signal wiring check, etc. This operation must be performed in the servo off state (SON signal off).

Operation

Call the display screen shown after power-on.

Using the "MODE" button, show the diagnostic screen.

Press UP twice.

Press SET for more than 2 seconds.
