4. Command explanations
4.1. General information
The following is describing the individual interface commands broken down into the four groups below:
- operating commands [ commands required during operation ]
- parameter commands [ commands for SPA parameterization ]
- identifier commands [ commands to indicate or alter the device identifier (address)]
- specific commands [ commands for specific functions as device reset or version number readout]
The following abbreviations are applied:
SOH = start of heading (header token)
EOT = end of transmission (footer token)
Adr = device identifier, including offset 20h
Cmd = command
Sub = sub-Command
Data = data transmitted or received
CRC = checksum (cyclic redundancy check)

Significance
C (43h) 3 / 11 X - - - Check if actual value = target
D (44h) 1 X X X - Start motor
F (46h) 4 X - - - Read device status and error
R (52h) 6 X - - - Read actual value
S (53h) 8 X X - X Read / write target
U (55h) 6 X X - - Offset
V (56h) 2 X X X X Read / write profile number
Z (5Ah) 6 X X X X Set preset
t (74h) 6 - X - - Transmit tool number
u (75h) 6 - X - - Transmit optional column of figures
4.2.1. Check Position „C“ (43h)
This command provides the alignment status of target versus actual value. If the actual value is within the target
tolerance window, the response will be „o“ (6Fh) for OK together with the current profile number. If the actual
value is outside the tolerances, „x“ (78H) followed by the current profile number will be replied. In case of any
SPA error occurred, the response will be “e” together with the active profile number.
Example: (active profile number = 05)
SOH Adr Cmd EOT CRC
Transmission
01h 20h 43h 04h 0Ah
Response if actual value within the tolerances:
SOH Adr Cmd Status Profile no. = 05 EOT CRC
Response
01h 20h 43h
6Fh 30h 35h
04h A5h
Response if actual value is outside the tolerances:
SOH Adr Cmd Status Profile no. = 05 EOT CRC
Response
01h 20h 43h
78h 30h 35h
04h 1D
Following values relating to status are possible:
Status Significance
o (6Fh) Actual value = target
x (78h) Actual value ≠ target
e (65h) SPA error
