Instruction Manual PSE2xxMod

Remarks:
1) The 3 parameters
“referencing value” (HR 48/49), “actual value assessment,
numerator
” (HR 45) and “actual value assessment, denominator” (HR 46) have an
influence on the 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).
2) When changing the direction of rotation (HR 44), the referencing value (HR 48/49)
and the upper and lower limit (HR 52/53 and HR 54/55) are set to delivery state.
3) 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 and
lower limit, the positioning window (HR 56) and the length of loop (HR 57/58) are
recalculated.
4) When changing the referencing value (HR 48/49), the target value, the actual
value and the upper and lower limit are recalculated.
5) 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 limit (HR 52/53),
lower limit (HR 54/55),
positioning window (HR 56),
length of loop (HR 57/58)
6) In order to save the settings permanently in the EEPROM, write 1 to HR 116. As
soon as reading of HR 116 shows 0, the saving is finished.
Referencing value (HR 48/49):
The referencing process affects all transferred values, i.e., the target value, actual
value and upper and lower limit.
There are two ways of setting the referencing value:
1) Directly, by writing the referencing value to HR 48/49.
2) Indirectly, by writing an actual value to HR 2/3. 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 HR 48/49.
When changing the referencing value, the target value, the actual value and and the
upper and lower limit are recalculated automatically.
The removal of the
motor
power supply has no affect on the internal
measuring system.
d)
Internal measuring system (applys for “multiturn” variants)
The multiturn variants of the PSE2xxMod actuator include an absolute measuring
system with measurement range of 68 rotations.
The mapping of the desired positioning range to the physical positioning range is
done with the help of the parameter ‘upper mapping end’ (HR 50/51).
In the delivery state, the drive is at position 13600, the upper limit switch is set to
26400 and the lower limit switch is set to 800, yielding a positioning range of ±32
rotations (±128
00 increments). So if the desired positioning range doesn’t exceed ±32
rotations, in delivery state none of the following actions to adjust the positioning range
have to be taken.
