Parameters 459
90.63 Feed constant
numerator 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
90.05
Load position scaled . Note that the load position is only
updated after new position input data is received.

90.65 Pos counter init
value Defines 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 .

90.66 Pos counter init
value source Selects the source of the initial position 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 (in decimal format).

90.67 Pos counter init
cmd source Selects a digital source (for example, a limit switch connected
to a digital input) that initializes the position counter. When the
digital source activates, the value selected by
90.66 Pos
counter init value source is assumed to be the position of the
load.
Note: Position counter initialization can be prevented by
parameter 90.68 Disable pos counter initialization .
