POINT
Keep the servo-on command (from controller) and ready-on command (from
controller) on while the forced stop command (from controller) or EM2 (Forced
stop 2) is off. When the servo-on command (from controller) and ready-on
command (from controller) are off, forced stop deceleration is not performed.
