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 = Po 4029 rotations
set SDO #2028 to 1611600.
b) After assembly, the displayed position is 804000. However, the
positioning range should point exclusively to the right (or top)
upper mapping end = Po 4029 rotations
set SDO #2028 to 2415600.
c) After assembly, the displayed position is -804400. However, the
positioning range should point exclusively to the left (or bottom)
upper mapping end = Po 3 rotations
set SDO #2028 to -803200.
Comments:
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 1200 increments), because the highest possible position value is
3 rotations below the upper mapping end. The smallest possible position
value is 4029 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) Actual value of numerator (SDO #2010) = 400
c) Actual value of denominator (SDO #2011) = 400
These 3 SDOs 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 (SDO #202C) is changed, the reference value
(SDO #2004), the upper mapping end (SDO #2028) and the upper and
lower limit switches (SDO #2016 and #2017) will be reset to the delivery
states.
4)
If the upper mapping end (SDO #2028) is changed, the upper and lower
limit switches (SDO #2016 and #2017) will be reset to the delivery states.
