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 limit (SDO #2016)
will be set to the value [upper mapping end - 3 rotations x scaling] and the lower
limit (SDO #2017) to the value [upper mapping end - 253 rotations x scaling]. This
results in a positioning range of 250 rotations.
5) When changing the actual value assessment numerator or denominator (SDO
#2010 or #2011), the target value, the actual value, the referencing value, the
upper mapping end, the upper and lower limit, the drag error, the positioning
window and the length of loop are re-calculated.
6) When changing the referencing value (SDO #2004), 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 (SDO #202C),
actual value assessment, numerator (SDO #2010),
actual value assessment, denominator (SDO #2011)
b) referencing value (SDO #2004)
c) upper mapping end (SDO #2028)
d) upper limit (SDO #2016),
lower limit (SDO #2017),
drag error (SDO #2005),
positioning window (SDO #2006),
length of loop (SDO #201F)
8) In order to save the settings permanently in the EEPROM, write 1 to SDO #204F.
As soon as reading of SDO #204F shows 0, the saving is finished.
Referencing value (SDO #2004):
With the help of the referencing value (SDO #2004) a shift of the whole range of
values can be reached. 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 SDO #2004.
2) Indirectly, by writing an actual value to SDO #2003. This makes it possible to
a
ssign 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 SDO #2004.
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.
