Forced Stop Deceleration Function - Mitsubishi Electric MR-J4-10A(-RJ) Instruction Manual

3.7 Forced stop deceleration function

3.7.1 Forced stop deceleration function
When EM2 is turned off, dynamic brake will start to stop the servo motor after forced stop deceleration.
During this sequence, the display shows [AL. E6 Servo forced stop warning].
During normal operation, do not use EM2 (Forced stop 2) to alternate stop and drive. The servo amplifier life
may be shortened.

POINT
When alarms not related to the forced stop function occur, control of motor
deceleration cannot be guaranteed. (Refer to chapter 8.)
In the torque control mode, the forced stop deceleration function is not available.
Disable the forced stop deceleration function for a machine in which multiple
axes are connected together, such as a tandem structure. In this case, when an
alarm occurs, the servo motor will stop with the dynamic brake.
