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.
If the values of the upper mapping end (SDO #2028) and/or the limit switches
(SDO #2016 and #2017) are sent by default each time the unit starts up, the new
referencing value must be included in these values if necessary. This can be done,
for example, by defining base values (which apply in the case of "referencing value
= 0"), to which the respective current value of the referencing value is then added.
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),
position scaling, numerator (SDO #2010),
position scaling, 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
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 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.
