The parameter value (PWE) is always transferred as a double word (32
bits). Only one parameter value can ever be transferred in a telegram.
A 32-bit parameter value is composed of PWE1 (least significant word,
3rd word) and PWE2 (most significant word, 4th word).
A 16 bit parameter value is transferred in PWE1 (least significant word,
3rd word). In this case, you must set PWE2 (most significant word, 4th
word) to the value 0.
Source for the ON/OFF1 command (control word 1, bit 0):
P554 (=22A Hex)
Change parameter value of index 1 to the value 3100.

Two unambiguous CAN identifiers are needed for parameter
processing, one for the PKW task and one for the PKW reply. In
contrast to other protocols, the CAN protocol only recognizes identifiers
and not node addresses. Practical experience shows, however, that it is
useful to define node addresses here as well for reasons of clarity. For
parameter processing, the individual CAN identifiers of the drive can
thus be generated from the node address (P918 "CB bus address") and
the basic identifier value (P711 / P696 "CB parameter 1").
A parameter on a gray background is only valid for MASTERDRIVES
with CU1, CU2 or CU3.
