Examples:
a) After mounting the drive, the position 0 is displayed (which corresponds to the delivery
state). The positioning range should point exclusively to the right (or top)
Upper mapping end = Po4,029 rotations
Set SDO #2028 to 1,611,600.
b) After assembly, the displayed position is 804,000. However, the positioning range
should point exclusively to the right (or top)
Upper mapping end = Po4,029 rotations
Set SDO #2028 to 2,415,600.
c) After assembly, the displayed position is -804,400. However, the positioning range
should point exclusively to the left (or bottom)
Upper mapping end = Po3 rotations
Set SDO #2028 to -803,200.
Notes:
1)
When calculating the upper mapping end (SDO #2028) (as in the above examples), it is
essential to include a safety margin of 3 rotations (by default 1,200 increments), because
the highest possible position value is 3 rotations below the upper mapping end. The
smallest possible position value is 4,029 rotations below the upper mapping end.
2)
The numbers of increments or position values indicated relate to the following settings,
which correspond to the delivery state:
a) Reference value (SDO #2004) = 0
b) Position scaling, numerator (SDO #2010) = 400
c) Position scaling, denominator (SDO #2011) = 400
These 3 parameters affect the above numbers of increments or position values: The
reference value can be used to shift the range of values, the numerator/denominator to
stretch or extend the range of values (see below).
3)
If the direction of rotation is changed (SDO #202C), the reference value (SDO #2004), the
upper mapping end (SDO #2028) and the upper and lower limits (SDO #2016 and #2017)
will be reset to the delivery states.
4)
When the upper mapping end is changed (SDO #2028), the upper and lower limits
(SDO #2016) will be reset to the delivery states.
5)
If the positioning scaling is changed (numerator: SDO #2010 or denominator: SDO #2011),
the target value, actual value, reference value, upper mapping end andthe upper and lower
limits, positioning window and length of loop will be recalculated.
6)
If the reference value is changed (SDO #2004), the target value, actual value, upper
mapping end and the upper and lower limits will be recalculated.
