1.3.1.3 Restart
The restart behaviour of the drive can be parameterised (C15300).
ƒ The "acknowledged restart" setting requires an acknowledgement to the safety
module. The acknowledgement is made via:
– Signal at the AIS input (with a signal time of 0.3 ... 10 s)
– Signal via the "PS_AIS" time (PROFIsafe)
ƒ An error stop requires an acknowledgement (AIE), before the restart can be
acknowledged.
ƒ The "Automatic restart" setting requires an acknowledgement at the master
control.
ƒ With active cascading (C15035 as of SM301 V1.1) an "Automatic restart" after STO,
SS1 is not possible.
Danger!
When the request for the safety function is deactivated, the drive can restart
automatically. The behaviour can be set via the parameter "Restart behaviour"
(C15300/1/2).
In the case of an automatic restart, you must provide external measures which
ensure that the drive only restarts after an acknowledgement (EN 60204).
