Is it parameter driven.

Yes it is parameter driven, but very few people change from the standard sequence control. Check Parameter P601, this will normally contain B124 which is the energise main contactor. This comes from the sequence control state "Ready for Pre-Charge", kind of inbetween "Ready for Switch On" and "Pre-Charging"

Refer to Function diagrams 91 and the state diagram in FD 520.
