Pos counter init value
int / uint32
Selects the source of the initial position integer value. When
the source selected by 90.67 Pos counter init cmd source
activates, the value selected in this parameter is assumed
to be the position of the load.

Bit 4 of 90.35 Pos counter status is cleared. Reinitialization
of position counter is recommended.

re-initialization
1Position counting resumes from the previous value over a
loss of load feedback or control unit reboot. Bit 4 of 90.35
Pos counter status is not cleared, but bit 6 is set to indicate
that an error has occurred.
Note: 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.

Parameters 90.63 and 90.64 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 90.7
Load position scaled int. Note that the load position is only
updated after new position input data is received.

0.000 / real32Defines an initial position (or distance) for the position
counter (as a decimal number) when parameter 90.66 Pos
counter init value source is set to Pos counter init value.
The number of decimal places is defined by parameter
90.38 Pos counter decimals.
