■
Turning the quick stop command (from controller) or EM2 (Forced stop 2) on/off [G] [WG]
In the torque mode and continuous operation to torque control mode, the forced stop deceleration function
cannot be used.
Keep the servo-on command (from controller) and ready-on command (from controller) on while the quick
stop command (from controller) or EM2 (Forced stop 2) is off. When the ready-on command (from controller)
is off, Tb [Pr. PC02 Electromagnetic brake sequence output] does not function.
MBR is turned off after the servo motor stops through forced stop deceleration, then the base circuit is turned off after the
base circuit shut-off delay time.
*1 ON: Electromagnetic brake is not activated
OFF: Electromagnetic brake is activated
*2 The model speed command is a speed command generated in the servo amplifier for forced stop deceleration of the servo motor.
