● The "automatic restart" function is only activated on the "SERVO/VECTOR" drive object
(p1210).
● In addition to the "AR" function, the following conditions must be fulfilled:
– The "flying restart" function (p1200) must be activated on the "VECTOR" drive object so
– The supply voltage must be reliably available at the Infeed Module (before the switch-on
Individual steps when restarting:
● After the line supply returns and the electronics has booted, the faults that have occurred at
the "SERVO/VECTOR" drive object as a result of its automatic restart are acknowledged
depending on the settings in p1210.
● The faults of the X_INF drive object are acknowledged via the BICO connection from
r1214.3 to p2105.
● The ON command (p0840) for the Infeed Module is generated via the binector output
"control contactor" of the "SERVO/VECTOR" drive object (p0863.1).
It is AND'ed with the negated binector output "Switching on inhibited" of drive object "X_INF"
(r0899.6) so that when the Control Unit restarts (powers up after the 24 V returns), the
necessary signal edge is generated.
● The switch-on attempt is interrupted if, during the restart, a fault occurs in the Infeed Module
(drive object X_INF).
