(2) Timing chart
When EM2 (Forced stop 2) turns off, the motor will decelerate according to [Pr. PC24 Forced stop
deceleration time constant]. Once the motor speed is below [Pr. PC07 Zero speed], base power is cut
and the dynamic brake activates. For MR-J4W_-B servo amplifiers, forced stop deceleration operates for
all axes.
