Operating modes

Overview
The following operating modes are implemented on the FM 353:
S Jogging (ER)
S Open-loop control (STE)
S Reference point approach (REF)
S Incremental relative (SMR)
S MDI (Manual Data Input)
S Automatic (A)
S Automatic single block (AE)
Selecting the mode
By calling POS_CTRL, the mode (coding) entered by the user program in the user
data block is called to transfer the operating mode (code) to the FM 353.
The axis is controlled by enabling and disabling appropriate control signals.
Checkback signal for mode
When the specification is allowed, the FM 353 feeds back the specified 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 checkback is
performed after the movement in the old mode is completed.
This does not apply to changes between Automatic and Automatic Single-Block
mode.
