Upper software end
position Defined end position on the side opposite the machine zero
point which is monitored by the SPC200 and which must not
be overrun. The upper software end position refers to the
machine zero point and represents the upper limit of the
positioning range.
Permitted: 0.0 ... 10.0000 [mm]
If both software end positions are set to 0," their function
will have no effect.
Reference position Coordinate of the reference point related to the machine zero
point. The machine zero point is defined by this value based
on the switching point of the reference switch.
Permitted: 0.0 .. 10.0000 [mm]
The exact position of the switching point of the reference
switch depends on the selected reference travel mode.
Reference speed factor With this factor the positioning speed V
Ref
of the reference
travel, related to the configured maximum speed, is deterĆ
mined (see Fig. 4/6).
Permitted: 0.01 ... 1.00
Caution
By unfavorable choice of the reference speed factor resonĆ
ance effects can occur with the reference travel of the axis.
Consider the manufacturer data for the permitted operatĆ
ing conditions of the used motors and drives, e.g. for the
permitted speeds.
Recommendation:
Do not set the reference speed less than the start−stop freĆ
quency.
