If parameterised appropriately with "Activate quick stop ramp in basic unit" (P0B.02), the motor con­
troller is instructed via the "Quick stop" cable to stop the drive.
After the time "Time delay until monitoring starts" (P0B.00) has elapsed, the drive is monitored to
check it is idling. At this time, the output "Safe state reached" becomes active if the safety condition is
not violated.
Whilst the time P0B.00 elapses, position monitoring is not yet active. After P0B.00 has elapsed, the
current position is saved and is used as the setpoint for the position to be monitored. The position is
monitored by comparing the current position value at regular intervals with the saved value.
After the request of the safety function SOS, the following times elapse until the safety function is ac­
tivated and errors are detected:
Time delays from VIN_SOS_RSF
VOUT_SOS_SFR
