STP-AC5, SRV-AC3

Denes 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 congured as a Tach Output, or a General Purpose output for use with other types of output

commands. There are three states that can be dened:

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

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. Parameter #2 is not dened 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 - Congures 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
