4.5.8 Output signal (DO) forced output
POINT
When the servo system is used in a vertical lift application, turning on MBR
(Electromagnetic brake interlock) 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.
Output signals can be switched on/off forcibly 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
SON (Servo-on).
Operation
Call the display screen shown after power-on. Using the "MODE" button, show the diagnostic screen.
