[2] When only the external emergency stop is input
If only the external emergency stop is input, all the drive units that share one NC communication enter an
emergency stop state and deceleration control (servo/spindle) or dynamic brake stop (servo) is executed. At
this time, the axis to which the external emergency stop is input enters "in external emergency stop" (EA
display). The contactor is turned OFF in accordance with the gate off delay time (SV055/SP055), as the NC
emergency stop is not input and the ready signal is not turned OFF.
[3] When only the NC emergency stop is input
Motors of all axes enter deceleration stop in the same sequence as normal operation (when both NC and
external emergency stop signals are input) and the contactor is shut off. In case that all axes stop is not
confirmed and the ready signal is not turned OFF, the contactor is shut off in accordance with the max. gate off
delay time (SV055/SP055) which is set to the contactor control axis.
