Parameter Channel [4 Word DI/DO]
The Parameter Channel module allows access to parameters, variables, curves, error log
and command table. Also restart, start and stop of the drive is possible. Of course the
Parameter Channel module works independently from the MC Cmd Interface. For this reason
changing a parameter and sending a motion command can be done in parallel.

The Parameter Channel Control is split in two parts:
•
Parameter Command ID to be executed (bits 8-15), see table Command ID
•
Command Count (bits 0-3)

The Parameter Channel Status is split in two parts:
•
Parameter Status (bits 8-15), see table Parameter Status
•
Command Count Response (bits 0-3)
Command Count
A new command is only evaluated, if the value of the command count changes. In the
easiest way bit 0 could be toggled.
Parameter Command ID
This selects the command.
Possible Commands are:
