Using this BICO interconnection, a drive object (DO) x_Infeed can be switched-in
by a vector drive object. This power-on version is mainly used for chassis units, if
only a line module and one Motor Module are used. If the associated application
requires an automatic restart function then the following procedure is recommen-
ded in order to implement it:
S The automatic restart function is activated on the DO vector (p1210).
S In addition to the automatic restart function, the flying restart function (p1200)
must be activated on DO vector if it must be assumed that an automatic restart
must be made for a motor that is still rotating.
Individual steps when restarting:
S After the line supply returns and the electronics has booted, the faults that have
occurred at DO vector as a result of its automatic restart are acknowledged
depending on the settings in p1210.
S The faults of the DO x_Infeed are acknowledged via the connection r1214.4 =>
p2105.
S The ON command (p0840) for the infeed is generated via the binector output
"control line contactor" of the DO vector (p0863.1).
S The power-on attempt is interrupted if, during the new power-on sequence, a
fault occurs on the DO x_Infeed. The fault is communicated to the DO vector
via the BiCo connection p1208.0 => r2139.3 shown above.
S The automatic restart of the DOs x_Infeed have absolutely no significance for
the described power-on version.
