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).
