Calculation of the
velocity_encoder_factor
consists in principle of two parts: a conversion
factor from internal length units into
position_units
, and a conversion factor from internal
time units into user-defined time units (e.g. from seconds into minutes). The first part
corresponds to the calculation of the
position_factor
; for the second part, an additional
factor is added to the calculation:
time_factor_v
Ratio between internal time unit and user-defined time unit.
(e.g.
1 min =
1
/
4096
4096 min
)
gear_ratio
Gear ratio between revolutions at the drive-in (R
IN
) and revolutions
at the drive-out (R
OUT
)
feed_constant
Ratio between revolutions at the drive-out (R
OUT
) and movement in
position_units
(e.g. 1 R = 360°)
