When you change the initialization function of software version V1.3x to
V1.40 and higher, or VC firmware from 3.22 to 3.23 and higher, the
behavior of the converter also changes (reverting to the behavior of
software versions V1.2x and lower again) as follows:
If the electronics supply is switched off on a converter that is in state
"READY" and is connected to an automation system via a field bus
(PROFIBUS, CAN, DEVICE-NET, or CC-Link), this causes a fault
message for this converter in the automation system.
If the automation system nevertheless sends a control word STW1 with
valid authorization (bit 10 = 1) and a pending ON command (bit 0 = 1)
to this converter, this can cause the converter to switch on and go
straight into "OPERATION" state when the electronics supply is
connected at the converter.

Please note the basic parameter differences (described below) to units
with the old function classes FC (CU1), VC (CU2) and SC (CU3).
These parameter numbers are printed on a dark gray background for
purposes of distinction.
