Controlling a Brake
Example
The relay output of the Ultra3000 is suitable for directly controlling a
motor brake, subject to the relay voltage limit of 30V dc, and the relay
current limit of 1A dc. For brake requirements outside of these limits,
an external relay must be used. If a transistor output is used, a control
relay is also required.
The following table lists Allen-Bradley motors that are compatible
with the internal relay output (CN1, pins 43 and 44), when used for
controlling a brake. All other motors require an external control relay.
1
Applies to 230V and 460V motors.
Figure B.19 shows an example configuration using Digital Output 1
and an external control relay to control a motor brake which exceeds
internal relay ratings.
