4.2.4. Read current value, command „R“ (52h)
This command is for readout the 6-digit current value (bottom display line). The amount of data is always 6
bytes. In case of a negative value, the “-“ sign (2Dh) together with 5 data bytes is replied. Positive values are
represented by 6 data bytes without sign. Values of less than 6 (5) digits will come with preceding zeroes.
Example: Current value = -32,50

4.2.5. Read / write target (profile), command „S“ (53h)
This command is for readout the presently active target or for programming respectively reading a specific
target. The data are composed of profile number (2 bytes) and target (6 bytes). Important: Negative targets
come by 5 digits only (see example no. 3).
Example 1: Read target of the active profile (current profile number = 12; target = 12,50)

Direct positioning „SD“
This command may be utilized for direct positioning operations. Only the target less any profile number is
transmitted to SPA. The profile number after the command “S” is replaced by sub command “D” (0 =
dimension). Motor start requires transmission of the additional motor start command “D”.
Example 4: Write position value for direct positioning (less profile)
SOH Adr Cmd Sub Position value = 278,25 EOT CRC

Response
01h 20h 53h 44h 30h 32h 37h 38h 32h 35h 04h 6Bh
Note: The position value is saved in the non-volatile memory and will be retained in case of power failure. In this
case the previously selected profile will be utilized again.
