Operating Modes
Overview
The following operating modes are implemented on the FM 453:
Selecting the Mode
FC MODE_WR is called up in order to transfer the operating mode (code),
which the user program entered in the user data block, to the FM 453.
The axis is controlled by enabling and disabling appropriate control signals.
Checkback Signal
When the specification is allowed, the FM 453 feeds back the specified mode
for Mode
to the user program. If this checkback mode matches the specified one, the
mode is active.
Changing Modes
Changing modes triggers an internal stop.
If a mode change is attempted while a traversing movement is in progress,
the modes are not switched until the axis comes to a stop. The mode check-
back is performed after the movement in the old mode is completed.
This does not apply to changes between Automatic and Automatic Single-
Block mode.
