4.2.7. Align current value with preset, command „Z“ (5Ah)
The Z command is for setting the current value to any optional position. The required position value is
transmitted to the SPA. The SPA will calculate a so-called “preset offset” -value relating to the true absolute
sensor position. When calculating the preset offset the already programmed offset transmitted by command “U”
will be considered, so that after having accomplished the “Z” command the current value always equals the
preset.
The current value displayed is composed as follows:
Current value
Anz
= current value
Abs
+ Preset offset + Offset
Current value
Anz
current value displayed and read out by interface
Current value
Abs
internal absolute current value.
Preset offset Offset generated by command „Z“.
Offset Additional offset defined by command „U“. This function however must be enabled in
command bit parameter ‚a’ (61h), otherwise offset = 0.
Example 1: Readout current 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: : Align actual value with 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: Align actual value with preset at 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
4.2.8. Readout parameter tool number, command „t“ (74h)
This command is for displaying a 6-digit tool number in the upper line of the display. The tool number is
indicated without dot respectively comma. Preceding zeroes as well as both direction arrows are suppressed.
The bottom line still indicates the current value.
The number is shown on the display until any command except „t“, „u“, „R“ or “T” is received by interface. The
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
