operational" can be made via a special signal on the MotionBus (CAN).
A status change from "Pre−operational" to "Operational" is possible through:
l Master function of a higher−level host system

automatically changed for the entire drive system after mains connection
when the boot−up time set in C0356/1 has elapsed.
l Reset node via C0358 ( ^ 206)
l With a binary input signal "Reset node", which can be set accordingly.
