6.8 Output signal (DO) forced output
POINT
When the servo system is used in a vertical lift application, turning on the
electromagnetic brake interlock (MBR) by the DO forced output after assigning it to
connector CN1 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 by turning off the servo-on (SON).
