Channel Enable Words
A Channel Enable Word is used for each channel (output words 0, 4, and
8), where:
Bit # Name

The Channel Enable Word is a "master" enable/disable switch for
communications on each channel. The actual output/input data being
sent/received is determined by Parameter 07 - [I/O Config 1],
Parameter 24 - [I/O Config 2] and Parameter 41 - [I/O Config 3].
Important: If the Channel Enable bit is transitioned from ON ("1") to
OFF ("0"), the connected drive product will fault.
