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.

Parameter Channel Control
Parameter Command ID to be executed Reserved Command Count
15 14 13 12 11 1 9 8 7 6 5 4 3 2 1
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 -3)
Parameter Channel Status
Parameter Status Reserved Command Count
Response
15 14 13 12 11 1 9 8 7 6 5 4 3 2 1
The Parameter Channel Status is split in two parts:
•Parameter Status (bits 8-15), see table Parameter Status
•Command Count Response (bits -3)
Command Count
A new command is only evaluated, if the value of the command count changes. In the
easiest way bit could be toggled.
Parameter Command ID
This selects the command.
Possible Commands are:
Command ID Description
h No Operation
Parameter Access
1 h Read ROM Value of Parameter by UPID
11h Read RAM Value of Parameter by UPID
12h Write ROM Value of Parameter by UPID
13h Write RAM Value of Parameter by UPID
14h Write RAM and ROM Value of Parameter by UPID
15h Get minimal Value of Parameter by UPID
16h Get maximal Value of Parameter by UPID
17h Get default Value of Parameter by UPID
