POINT
When LSP/LSN is turned on during a forced stop deceleration, the motor will
stop depending on the setting of [Pr. PD30] as follows.
[Pr. PD30] Stop system
_ _ _ 0 Switching to sudden stop
_ _ _ 1 Continuing forced stop deceleration
When EM2 (Forced stop 2) turns off, the motor will decelerate according to [Pr. PC51 Forced stop
deceleration time constant]. Once the motor speed is below [Pr. PC17 Zero speed] after completion of
the deceleration command, base power is cut and the dynamic brake activates.
