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 (HR 56) and the
length of loop (HR 57/58) 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)
d) upper limit (HR 52/53),
lower limit (HR 54/55),
positioning window (HR 56),
length of loop (HR 57/58)
8) 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, 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 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, automatically the target value, the actual value,
the upper mapping end and the upper and lower limit are recalculated.
The removal of the
motor
power supply has no affect on the internal
measuring system.
e) Using actual value assessment factors to set the spindle pitch
HR 45 (numerator factor) and HR 46 (denominator factor) can be used to represent
any desired spindle pitch.
Both factors are set to a value of 400 by default, resulting in a resolution of 0.01 mm
at a spindle pitch of 4 mm.
The denominator factor serves as a simple means of setting the spindle pitch and
resolution.
The numerator factor
is primarily used for setting “unlevel” resolutions.
