AXISx_CFG subroutine

Description
CALL AXISx_CFG,
START, Done, Error
The AXISx_CFG subroutine (Reload Configuration) commands the Axis
of Motion to read the configuration block from the location specified by
the configuration/profile table pointer. The Axis of Motion then com-
pares the new configuration with the existing configuration and per-
forms any required setup changes or recalculations.

Turn on the EN bit to enable the subroutine. Ensure that the EN bit stays on until the Done
bit signals that the execution of the subroutine has completed.
Turn on the START parameter to send a CFG command to the Axis of Motion. For each
scan when the START parameter is on and the Axis of Motion is not currently busy, the
subroutine sends a CFG command to the Axis of Motion. To ensure that only one command
is sent, use an edge detection element to pulse the START parameter on.
The Done parameter turns on when the Axis of Motion completes this subroutine.
The Error parameter (Page 659) contains the result of this subroutine.
