When the servo system is used in a vertical lift application, turning on MBR
(Electromagnetic lock interlock) by the DO forced output after assigning it to
connector CN1 will release the electromagnetic lock, causing a drop. Take drop

output signal wiring check, etc. This operation must be performed in the servo off state by turning off the SON
(Servo-on).
