Illegal axis identifiers
Notes:
The DEC setting only takes effect when the specified axis is
in closed-loop operation (servo mode ON).
The lowest possible value for <Deceleration> is 0.
DEC changes the value of the Closed Loop Deceleration

The maximum value that can be set with the DEC
command is specified by the Maximum Closed-Loop
Deceleration (Phys. Unit/s
