3 BASIC FUNCTION
3.16 Electromagnetic brake interlock function
■
Turning EM2 (Forced stop 2) off/on [A]
In the torque mode, the forced stop deceleration function cannot be used.
Keep SON (Servo-on) on while EM2 (Forced stop 2) is off. When SON (Servo-on) is turned off before EM2
(Forced stop 2), the operation state of the servo amplifier is the same as the following.

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.
