Setting Method [A]; Timing Chart [G] [Wg] - Mitsubishi Electric MR-J5 Series User Manual

Setting method [A]

Set [Pr. PA04.3 Forced stop deceleration function selection] to enable/disable the forced stop deceleration function. Setting
[Pr. PA04.3 Forced stop deceleration function selection] to "2" (Forced stop deceleration function enabled) operates forced
stop deceleration function when EM2 (Forced stop 2) is turned off. In addition, set the level of ZSP (Zero speed detection) and
the amount of time to reach 0 [r/min] or [mm/s] from the rated speed, by using [Pr. PC17 Zero speed] and [Pr. PC51
Deceleration time constant at forced stop].

Timing chart [G] [WG]

When EM2 (Forced stop 2) is turned off, the servo motor decelerates in accordance with the value of [Pr. PC24 Deceleration
time constant at forced stop]. Once the servo motor speed is below [Pr. PC07 Zero speed] after completion of the deceleration
command, base circuit is shut off and the dynamic brake activates.
