Safe Stop and Safe Stop with Door Monitoring Modes

Chapter 6

When Safe Stop 2 is executed, the Guard Gate drive output is on (status = 1)
until after standstill speed is reached or a fault occurs. Use this safe stop for
vertical load applications. The IGBT remains active, therefore follow the
examples on

page 57

to MAS before SS_Reset.

For Safe Stop 2, motion power is not removed when Standstill Speed is reached.

IMPORTANT

For Safe Stop 2, the Logix Designer application must monitor the state of the
Axis.GuardStopRequestStatus tag. After the tag becomes active and stop
monitoring expires, the program must issue an MAS instruction. Successful
SS_Reset is required prior to restarting the machine.
