Pos counter init
value int source
Selects the source of the initial position integer value. When

activates, the value selected in this parameter is assumed to
be the position of the load.

Pos counter error
and boot action
Selects how the position counter reacts to loss of load
feedback.
Request re-

is cleared. Reinitialization of
position counter is recommended.
0
Continue from
previous value
Position counting resumes from the previous value over a loss
of load feedback or control unit reboot. Bit 4 of
is not cleared, but bit 6 is set to indicate that an
error has occurred.
WARNING!
If load feedback is lost when the drive is in
stopped state or not powered, the counter is not
updated even if the load moves.

and
define the feed constant for the
position calculation:
The feed constant converts rotational motion into translatory
motion. The feed constant is the distance the load moves
during one turn of the motor shaft.
The translatory load position is shown by parameter
. Note that the load position is only
updated after new position input data is received.
