Direct positioning „SD“
This command may be utilized for direct positioning operations. Only the target less any profile number is trans-
mitted to SPA. The profile number after the command “S” is replaced by sub command “D” ( = dimension). Mo-
tor start enable requires transmitting in addtion motor start command “D”.
Example 4: Write position value for direct positioning operation (less profile)
SOH Adr Cmd Sub Position value = 278.25 EOT CRC
Transmission
01h 20h 53h
44h 30h 32h 37h 38h 32h 35h
04h 6Bh
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 is utilized again.
Transmitting targets with simultaneous motor start signal
Specific applications require autonomous re-alignment of shafts to the new target when it is received without
prior enable signal by command „D“. For this intention the following commands are available:
SPF transmits to SPA profile number together with motor start signal for automated positioning operations
SDF transmits to SPA position value together with motor start signal for automated positioning operations
The addressed SPA is enabled by adding sub-command „F“ to the respective basic command. Since it is a pure
individual positioning operation, defined groups are not affected. Collision prevention is up to the operator.
Example: Write specific target utilizing command „SPF“ (profile number = 17; target = -12.50)
SOH Adr Cmd Sub1 Sub2 Profile=17 Target = -12.50 EOT CRC
Transmission
01h 20h
53h 50h 46h
31h 37h 2Dh 30h 31h 32h 35h 30h 04h A0h
SOH Adr Cmd Sub1 Sub2 Profile=17 Target = -12.50 EOT CRC
Response
01h 20h
53h 50h 46h
31h 37h 2Dh 30h 31h 32h 35h 30h 04h A0h
4.2.6. Read / write offset „U“ (55h)
This command is utilized to read or write the offset that is added to the true actual value. First however the func-
tion must be enabled in command bit parameter ‚a’ (61h).
Example 1: Read offset
SOH Adr Cmd EOT CRC
Transmission
01h 20h 55h 04h 26h
Example 2: Write offset
SOH Adr Cmd Data (offset = –20.00) EOT CRC
Transmission
01h 20h 55h
2Dh 30h 32h 30h 30h 30h
04h C3h
Response in both examples:
SOH Adr Cmd Data (offset = –20.00) EOT CRC
Response
01h 20h 55h
2Dh 30h 32h 30h 30h 30h
04h C3h
4.2.7. Read / write profile number „V“ (56h)
This command is utilized to read the number of the presently active profile respectively for profile alteration.
Example 1: Read active profile (active profile number = 38)
SOH Adr Cmd EOT CRC
Transmission
01h 20h 56h 04h 20h
SOH Adr Cmd Profile no. = 38 EOT CRC
Response
01h 20h 56h
33h 38h
04h 28h
Response after reset upon having cleared all profiles:
SOH Adr Cmd Profile no. = FF EOT CRC
Response
01h 20h 56h
3Fh 3Fh
04h 16h
