2) Mount the drive in any position on the axle, close the collar, then adjust the
positioning range with the help of SDO #2028. SDO #2028 defines the upper end
of the positioning range. By default, the upper end is at +256 rotations (position
102400). If the positioning range doesn’t suit to the actual displayed position after
mounting the drive, the upper end of the positioning range can be adjusted
between -256 rotations and +512 rotations.
Examples:
a) After mounting the drive, the displayed position is 51200 (which corresponds
the delivery state). But the positioning range shall solely spread to the right
(resp. top)
Set SDO #2028 to 152400.
b) After mounting the drive, the displayed position is 100000. But the positioning
range shall solely spread to the right (resp. top)
Set SDO #2028 to 201200.
c) After mounting the drive, the displayed position is 2000. But the positioning
range shall solely spread to the left (resp. bottom)
Set SDO #2028 to 3200.
Remarks:
1) When calculating the upper mapping end (SDO #2028), a security reserve of 3
rotations has to be kept in mind (1200 increments by default, see the examples
above), because the highest possible position value is 3 rotations below the upper
mapping end. The lowest possible position value is 253 rotations below the upper
mapping end.
2) The above given increment and position values relate to the following settings,
which correspond to the delivery state:
a) referencing value (SDO #2004) = 0
b) actual value assessment, numerator (SDO #2010) = 400
c) actual value assessment, denominator (SDO #2011) = 400
These 3 SDOs have an influence on the above given increment and position
values: With the help of the referencing value a shift can be reached, with the help
of the actual value assessment numerator and denominator a stretching or
distension can be reached (see below).
3) When changing the direction of rotation (SDO #202C), the referencing value (SDO
#2004), the upper mapping end (SDO #2028) and the upper and lower limit (SDO
#2016 and #2017) are set to delivery state.
4) When changing the upper mapping end (SDO #2028), the upper and lower limit
(SDO #2016 and #2017) are set to delivery state.
5) When changing the actual value assessment numerator or denominator (SDO
#2010 or #2011), the target value, the actual value, the referencing value, the
upper mapping end, the upper and lower limit, the positioning window and the
length of loop are re-calculated.
6) When changing the referencing value (SDO #2004), the target value, the actual
value, the upper mapping end and the upper and lower limit are re-calculated.
7) If the user wants to go over any automatic re-calculation of values when setting up
the device, the optimum order of transfering the parameter is the following:
a) direction of rotation (SDO #202C),
actual value assessment, numerator (SDO #2010),
actual value assessment, denominator (SDO #2011)
b) referencing value (SDO #2004)
c) upper mapping end (SDO #2028)
d) upper limit (SDO #2016),
lower limit (SDO #2017),
positioning window (SDO #2006),
length of loop (SDO #201F)
8) In order to save the settings permanently in the EEPROM, write 1 to SDO #204F.
As soon as reading of SDO #204F shows 0, the saving is finished.
