To check whether the new profile has been adopted by all SPAs utilize check command „C“ (43h).
4.2.8. 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 the SPA. The SPA will calculate a so-called “preset offset” value relating to the true absolute encoder posi-
tion. 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: If the resolution is altered (see command “a”) from 1/100 to 1/10 or vice-versa, the previously pro-
grammed preset has to be set anew. The auto-calculated offset is provided in the previously selected resolu-
tion.
The actual value displayed is composed as follows:
actual value
displz
= actual value
abs
+ preset offset + Offset
Immediately after having accomplished command „Z“ applies preset value = current valuet-
displ
Current value
displ
actual value indicated in the display and read out by interface
Current value
abs
internal absolute actual value (not corresponding to the transmitted preset value).
Preset offset offset generated by command „Z“.
Offset Additional offset enabled by command „U“. This function must be enabled first in command
bit parameter ‚a’ (61h), otherwise the offset is 0.
