MPH-02, MPB-02, MPD-02 Operating Modes 7-3
DOK-INDRV*-MP*-02VRS**-FK01-EN-P
With the following exceptional circumstances, the desired operating mode
is not carried out in spite of the operating mode having been correctly
selected:
Drive error is present
The corresponding error reaction is carried out.
Fatal warning was triggered
The corresponding reaction is carried out.
A "drive command" (e.g. homing procedure, set absolute measuring
etc.) is executed
The command started is carried out.
Drive Halt
This drive function is carried out.

chapter "Master Communication"
In order to achieve a quick and smooth change of operating mode in
running operation, it is possible to make a "drive-controlled change of
operating mode". Drive-internally this procedure ensures that when the
operating mode is changed the transition is carried out in a synchronized
way, even if the command value changes abruptly.
Command Value Acceptance and Acknowledgment
Each preset command value is accepted immediately when the
respective command value parameter (e.g. S-0-0036, S-0-0080,
S-0-0258, ) is written in the case of the operating modes:
torque/force control
velocity control
position control with cyclic command value input
drive-internal interpolation
synchronization modes:
velocity synchronization with real/virtual master axis
phase synchronization with real/virtual master axis
electronic cam shaft with real/virtual master axis
In the positioning modes (drive-controlled positioning, positioning block
mode), however, the command value (target position, velocity, positioning
block, ...) is only accepted when the master explicitly requests this by a
"command value acceptance".
The command value acceptance is carried out in a different way,
according to the positioning mode or profile type:
operating mode "drive-controlled positioning"
acceptance of preset command value (position, velocity) by toggling
bit 0 in S-0-0346, Positioning control word
toggle mechanism
operating mode "positioning block mode"
acceptance of the positioning block selected via P-0-4026,
Positioning block selection by a 0-1 edge of bit 0 in P-0-4060,
Positioning block control word, when the parallel interface or, in the
case of field buses, the I/O mode is used as master communication
edge control
