Parameters 325
90.61 Gear numerator Parameters 90.61 and 90.62 define a gear function
between the motor and load speeds.

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 .

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 .
See also section Position counter (page 66 ).
The number of decimal places is defined by parameter
90.38 Pos counter decimals .

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).
