4. SAFETY OBSERVATION FUNCTION
(c) Stop with dynamic brake
When the SS1 function operates, the servo motor will be stopped with the dynamic brake.
For operation of the dynamic brake, also refer to each servo amplifier instruction manual.

(d) Stop with electronic dynamic brake
When the SS1 function operates, the servo motor will be stopped with the electric dynamic brake.
When the time has passed after the SS1 function start reaches the setting of [Pr. PF12 Electronic
dynamic brake operating time], the dynamic brake will be activated. If the setting of [Pr. PSA03
SS1/SS2 monitoring deceleration time] is shorter than that of [Pr. PF12 Electronic dynamic brake
operating time], the dynamic brake will be activated at the moment of reaching the set value of [Pr.
PSA03 SS1/SS2 monitoring deceleration time].
