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 current value. First however the
function 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 for readout 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
Example 2: Transmit new profile (new profile number = 17)
SOH Adr Cmd Profile no. = 17 EOT CRC
Transmission
01h 20h 56h 31h 37h 04h 3E
SOH Adr Cmd Profile no. = 17 EOT CRC
Response
01h 20h 56h 31h 37h 04h 3E
Example 3: New profile by broadcast command to all SPAs (Identifier = 99 (83h); new profile number = 17)
SOH Adr Cmd Profile no. = 17 EOT CRC
Transmission
01h 83h 56h 31h 37h 04h 04
Response Not confirmed
To check whether the new profile has been adopted by all SPAs utilize check command „C“ (43h).
