For the realization of any desired positioning range independent of the possible
positioning range which is defined by the mounting situation (physical positioning
range) there are the following two possibilities:
1) Move the axle (for example a spindle) to the desired position, then move the drive
(with opened collar) to the position value which belongs to the physical position of
the axle, only then close the collar.
Examples:
a) Move the axle in middle position, then move the drive at no-load (with opened
collar) also to middle position (position 13600), then close the collar. The drive
is now capable of moving 32 rotations (±12800 increments by default) in each
direction.
b) Move the axle completely to the left (resp. bottom), then move the drive at no-
load (with opened collar) without loop to the lowest position (position 800), then
close the collar. The drive is now capable of moving 64 rotations (±25600
increments by default) to the right (resp. top).
c) Move the axle completely to the right (resp. top), then move the drive at no-load
(with opened collar) to the highest position (position 26400), then close the
collar. The drive is now capable of moving 64 rotations (±25600 increments by
default) to the left (resp. bottom).
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 +68 rotations (position
272
00). 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 -68 rotations and +136 rotations.
Examples:
a) After mounting the drive, the displayed position is 13600 (which corresponds
the delivery state). But the positioning range shall solely spread to the right
(resp. top)
Set SDO #2028 to 40000.
b) After mounting the drive, the displayed position is 26400. But the positioning
range shall solely spread to the right (resp. top)
Set SDO #2028 to 52800.
c) After mounting the drive, the displayed position is 800. But the positioning range
shall solely spread to the left (resp. bottom)
Set SDO #2028 to 1600.
Remarks:
1) When calculating the upper mapping end (SDO #2028), a security reserve of 2
rotations has to be kept in mind (800 increments by default, see the examples
above), because the highest possible position value is 2 rotations below the upper
mapping end. The lowest possible position value is 66 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
