4.2.6. Set actual value as preset „Z" (5Ah)
Command "Z" is utilized to set the actual value at any optional value. The required position value is transmitted
to SPA. The SPA will calculate a so-called "preset offset" value relating to the true absolute encoder position.
When calculating the preset offset, any programmed offset transmitted by command "U" will be considered, so
that after having accomplished command "Z" the current value always equals the preset.
Note: When altering the resolution (see command „a") from 1/100 to 1/10 or vice-versa, any already assigned
preset must be assigned anew. The internally calculated offset is available in the resolution previously
programmed.
The indicated actual value is composed as follows:
actual value
Actual value
indicated actual value for readout by interface
Anz
Actual value
internal absolute actual value.
Abs
Preset offset
offset generated by command „Z".
Offset
supplementary offset defined by command „U". This function however must be enabled in
command bit parameter ‚a' (61h), otherwise applies offset = 0.

4.2.7. Indicate optional column of figures in upper line „t" (74h)
This command is utilized to indicate a 5-digit number in the upper line of the display. The numerical column is
indicated less dot respectively comma. Preceding zeroes as well as both arrows are suppressed. The bottom
line still indicates the actual value.
The numerals are indicated in the display until any command except „t", „u" or „R" is received by interface. The
number will be retained after power failure.
Example: (column of figures = 054321)
