Assigning control word bits
I/O profile
The I/O profile is extremely flexible in terms of assigning and switching the 16 control word bits.
To switch a control word bit using:
• An input from the terminals
• Or a control word bit from another communication channel
simply configure a switched assignment for the function input 
(CDpp)
, instead of a fixed assignment 
(Cppp)
.
Inputs and bits of the same order are switched.
Inputs LI1 to LI6 of the drive terminals can be used to switch control word bits 0 to 5.
With a logic I/O card using inputs LI7 to LI10, control word bits 6 to 9 can also be switched.
With an extended I/O card using inputs LI11 to LI14, control word bits 10 to 13 can also be switched.
Example
Function input A is always controlled by bit 1 of the CANopen control word.
Function input B is always controlled by input 
LI5
 on the terminals.
Depending on the value of 
LI2
, function input C is controlled:
• Either by input 
LI3
 on the terminals
• Or by bit 2 of the CANopen control word
Once a bit has been assigned to a switchable assignment, it can no longer be assigned to a fixed assignment, and vice versa.
Example: Once a function input has been assigned to CD04, it cannot be assigned to LI5, C104, C204, C304 or C404.
