12.2 Infeed switch on by a drive
Drive functions
916 Function Manual, 11/2017, 6SL3097-4AB00-0BP5
● 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).
● A fault in drive object "X_INF" is communicated to the "SERVO/VECTOR" drive object via
the BICO connection from p1208.0 to r2139.3 shown above.
● The automatic restart of the X_INF drive object has absolutely no significance for the
described switch-on version. It is deactivated for drive object "X_INF".
Unplanned motion when the automatic restart function is active
When the automatic restart is activated, when the line supply returns, unexpected motion
can occur that may result in death or serious injury.
• Take the appropriate measures on the plant/system side so that there is no safety risk
as a result of an unexpected restart.
