90.59 Pos counter init
value int source
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.

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

Bit 4 of 90.35 Pos counter status 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 90.35 Pos
counter status 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.

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 90.07
Load position scaled int. Note that the load position is only
updated after new position input data is received.
