3.15 Forced stop deceleration function
Timing chart [A]
When EM2 (Forced stop 2) is turned off, the servo motor decelerates in accordance with the value of [Pr. PC51 Deceleration
time constant at forced stop]. Once the servo motor speed becomes below [Pr. PC17 Zero speed] after completion of the
deceleration command, the base circuit will be shut off and the dynamic brake will activate.
