4.2.8. Set current value as preset „Z“ (5Ah)
Command “Z” sets the current value at any optional position. The required position value is transmitted to the
SPA which will calculate a so-called “preset offset” related to the true absolute encoder position. Any offset
which is set and transmitted by command “U” will be considered in the calculation, so that after execution of
command “Z” the current value is ever the preset.
The actual value in the display is composed as follows:
actual value
displz
= actual value
abs
+ preset offset + Offset
Current value
displ
actual value in the display which is read out via interface
Current value
abs
internal absolute current value
Preset offset offset calculated by command „Z“.
Offset Additional offset which may be set by command „U“. Firstly, the functionality must be en-
abled in command bit parameter ‚a’ (61h), otherwise the offset is 0.
Example 1: Read out the currently active preset
SOH Adr Cmd EOT CRC
Transmission
01h 20h 5Ah 04h 38h
SOH Adr Cmd preset = 2,50 EOT CRC
Response
01h 20h 5Ah 30h 30h 30h 32h 35h 30h 04h 27h
Example 2: Set current value as preset (preset = 17.25)
SOH Adr Cmd preset = 17,25 EOT CRC
Transmission
01h 20h 5Ah 30h 30h 31h 37h 32h 35h 04h 09h
SOH Adr Cmd preset = 17,25 EOT CRC
Response
01h 20h 5Ah 30h 30h 31h 37h 32h 35h 04h 09h
Example 3: Set current value as preset in all SPAs by broadcast command
SOH Adr Cmd preset = 17,25 EOT CRC
Transmission
01h 83h 5Ah 30h 30h 31h 37h 32h 35h 04h AAh
Response Not confirmed
4.2.9. Indicate tool number „t“ (74h)
The command writes a 6-digit tool number in the upper line of the display. The number is indicated without dot
respectively comma. Leading zeros as well as both direction arrows are suppressed. The lower line of the dis-
play still indicates the true current value.
The tool number will be displayed until any command except „t“, „u“ or „R“ is received via interface. The tool
number will be retained after power failure.
Example: (tool number = 654321)
SOH Adr Cmd Tool number = 654321 EOT CRC
Transmission
01h 20h 74h 36h 35h 34h 33h 32h 31h 04h 47h
SOH Adr Cmd Tool number = 654321 EOT CRC
Response
01h 20h 74h 36h 35h 34h 33h 32h 31h 04h 47h
