Forced Stop Deceleration Function - Mitsubishi Electric MR-J4W2-0303B6 Instruction Manual

3. SIGNALS AND WIRING

3.6 Forced stop deceleration function

3.6.1 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 run. 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 section 8.1.)
When SSCNET III/H communication shut-off occurs, forced stop deceleration
will operate. (Refer to section 3.7 (3).)
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. If an alarm occurs
with the forced stop deceleration function disabled, the servo motor will stop with
the dynamic brake.
