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 1200),
then close the collar. The drive is now capable of moving 250 rotations
(±100000 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 101200), then close the
collar. The drive is now capable of moving 250 rotations (±100000 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 HR 50/51. HR 50/51 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 HR 50/51 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 HR 50/51 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 HR 50/51 to 3200.
Remarks:
1) When calculating the upper mapping end (HR 50/51), 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 (HR 48/49) = 0
b) actual value assessment, numerator (HR 45) = 400
c) actual value assessment, denominator (HR 46) = 400
These 3 holding register 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 (HR 44), the referencing value (HR 48/49),
the upper mapping end (HR 50/51) and the upper and lower limit (HR 52/53 and
HR 54/55) are set to delivery state.
4) When changing the upper mapping end (HR 50/51), the upper and lower limit (HR
52/53 and HR 54/55) are set to delivery state.
5) When changing the actual value assessment numerator or denominator (HR 45 or
HR 46), 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 recalculated.
6) When changing the referencing value (HR 48/49), the target value, the actual
value, the upper mapping end and the upper and lower limit are recalculated.
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 (HR 44),
actual value assessment, numerator (HR 45),
actual value assessment, denominator (HR 46)
b) referencing value (HR 48/49)
c) upper mapping end (HR 50/51)
