POINT
In the torque control mode, the forced stop deceleration function is not available.
Keep the servo-on command (from controller) and ready-on command (from
controller) on while the forced stop command (from controller) or the EM2
(Forced stop 2) is off. When the ready-off command (from controller) is off, Tb
[Pr. PC02 Electromagnetic brake sequence output] does not function.
