Host Command Reference
STAC5-Q/IP, SVAC3-Q/IP
Defines usage of digital output Y2 as the Brake Output, which can be used to automatically activate and
deactivate a holding brake. Output Y2 can also be configured as a Tach Output, or a General Purpose output for
use with other types of output commands. There are three states that can be defined:
BO1: Output is closed (energized) when drive is enabled, and open when the drive is disabled.
BO2: Output is open (de-energized) when drive is enabled, and closed when the drive is disabled.
BO3: Output is not used as a Brake Output and can be used as a general purpose output.
NOTE: Setting the BO command to 1 or 2 overrides previous assignments of this output’s function. Similarly, if
you use the AO or MO command to set the function of the output after setting the BO command to 1 or 2, usage
of the output will be reassigned and BO will be automatically set to 3.
Command Details:
Structure BO{Parameter #1}{Parameter #2 (Flex I/O only}
Type BUFFERED
Usage READ/WRITE
Non-Volatile YES
Register Access None
Parameter Details:
Parameter #1 Output Usage (see above)
- units integer code
- range 1, 2 or 3
Parameter #2 (Flex I/O only) I/O Point (if applicable, see note below)
- units integer code
- range 1 - 4
NOTES:
• For drives with Flex I/O, the SD command must be executed to set an I/O point as an output before that
output can be assigned as the Brake Output.
• Parameter #2 only applies to drives equipped with Flex I/O. This includes the STM24SF and STM24QF.
Parameter #2 is not defined for drives equipped with standard I/O.
Examples:
All drives with standard I/O:
Command Drive sends Notes
BO1 - Brake Output will be closed when drive is enabled
BO BO=1
Drives with Flex I/O only:
Command Drive sends Notes
SD4O - Configures I/O 4 as output (see SD command for details)
BO14 - Brake Output is mapped to I/O point 4 and will be Closed when drive is
enabled
BO BO=14
