Direct positioning „SD“

This command is utilized for direct positioning operations. Only the current value without profile number will be
transmitted to the SPA.. Instead of transmitting the profile number, command “S” is followed by sub-command
“D” (dimension). Motor start requires the additional enable signal in command “D” .

Example: Set position value for direct positioning (without profile number):

SOH Adr Cmd Sub

Position value = 278,25

Note: The position value will not be saved in the non-volatile memory. Consequently it is not retained after
power off but the previously active profile will be restored.

Target transmission with simultaneous motor enable signal

Some applications require automated self-positioning of a specific shaft when being provided with the new tar-
get without prior transmission of the enable signal in command „D“. The following commands serve this inten-
tion:

SPF transmits the profile value to the SPA. Motor start enabled for automated positioning
SDF transmits the position value to the SPA. Motor start enabled for automated positioning

Attaching the sub-command „F“ to the respective basic command will enable the addressed SPA. Groups re-
main unaffected, since only specific individual positioning operations are required. The operator must see that
any collisions are avoided.

Example: Set a specific target using command „SPF“ (profile no. = 17; target = -12.50)

SOH Adr Cmd Sub1 Sub2 Profile=17

target = -12,50
