Chapter 6 Safe Stop and Safe Stop with Door Monitoring Modes
Automatic
If the SS Reset is configured as automatic, the drive always attempts a reset if it is
in the Safe State or has initiated a Stop Category. The reset is attempted when the
SS_In input transitions from OFF to ON or if SS_In is ON at powerup.
Manual
If the SS Reset is configured as manual, the reset is attempted when the SS_In
input is ON and the Reset_In input is ON.
Manual Monitored
A manual monitored reset requires an OFF to ON to OFF transition of the
Reset_In input.
If at any time before the closing and opening of the Reset_In input, the SS_In
input transitions from ON to OFF, the reset is aborted.
Faults
If a fault occurs, other than an Invalid Configuration fault or an ESM
Monitoring fault, the SS_In input must turn OFF and ON again to reset the
GuardStopInputCycleRequiredStatus bit before a successful SS Reset can occur.
Door Control
The status of door control logic (Lock or Unlock) and the Door Monitor Input
(DM_In), along with the drive’s location in the system [System Configuration]
and Door Control Output Type [Door Control Output] determine whether the
Door Control output (DC_Out) is locked or unlocked during normal operation.
When the DC_Out output has no faults, the drive is configured for Safe Stop,
and the drive is monitoring motion, the door control logic state is Locked. It
remains locked while a Safe Stop is being executed. For all Stop Categories except
Safe Torque Off without Standstill Checking, door control logic is set to Unlock
only when Standstill Speed has been reached. If the Stop Category is Safe Torque
Off without Standstill Checking, door control logic is set to Unlock when the
Stop Delay [Maximum Stop Time] has elapsed, regardless of speed.
