Instruction Manual PSE2xxDN
27
Remarks:
1) When calculating the upper mapping end (attr. 40), 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 (attr. 4) = 0
b) actual value assessment, numerator (attr. 16) = 400
c) actual value assessment, denominator (attr. 17) = 400
These 3 attributes 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 (attr. 44), the referencing value (attr. 4),
the upper mapping end (attr. 40) and the upper and lower limit (attr. 22 and 23) are
set to delivery state.
4) When changing the upper mapping end (attr. 40), the upper and lower limit (attr.
22 and 23) are set to delivery state.
5) When changing the actual value assessment numerator or denominator (attr. 16 or
17), the target value, the actual value, the referencing value, the upper mapping
end, the upper and lower limit, the positioning window (attr. 6) and the length of
loop (attr. 31) are re-calculated.
6) When changing the referencing value (attr. 4), 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 (attr. 44),
actual value assessment, numerator (attr. 16),
actual value assessment, denominator (attr. 17)
b) referencing value (attr. 4)
c) upper mapping end (attr. 40)
d) upper limit (attr. 22),
lower limit (attr. 23),
positioning window (attr. 6),
length of loop (attr. 31)
8) In order to save the settings permanently in the EEPROM, write 1 to attr. 79. As
soon as reading of attr. 79 shows 0, the saving is finished.
Referencing value (attr. 4):
The referencing process affects all transferred values, i.e., the target value, actual
value, upper mapping end and upper and lower limit.
There are two ways of setting the referencing value:
1) Directly, by writing the referencing value to attr. 4.
2) Indirectly, by writing an actual value to attr. 3. This makes it possible to assign any
“true” actual value to the current, physical actual value. The resulting difference is
then the referencing value. This value will immediately be included in calculations
for each transferred value and can also be read via attr. 4.
When changing the referencing value, automatically the target value, the actual value,
the upper mapping end and the upper and lower limit are re-calculated.
The removal of the
motor
power supply has no affect on the internal
measuring system (applys for signleturn and multiturn variants).
