3.3.2. Brake / Relay Interface (J103, TB103)
The brake relay is typically used to power a failsafe electromagnetic brake on a vertical
axis. This causes the brake to be engaged, holding the axis in position, unless it is
powered. Note, that the axis may move slightly as the brake is enabled and disabled but
will never drift or fall down. The design also allows the brake to be powered through the
existing encoder feedback cable without the need for additional wiring, as indicated in
Figure 3-15. Failsafe brakes used by Aerotech require a 24 VDC supply capable of
supplying 1 ampere of current.
This brake output may also be used as a general-purpose relay. For this reason, the
normally closed, normally open and common contacts are available on the TB206
connector of the -IO option.
See the BrakeOnDriveDisable axis parameter for information on activating the brake
output automatically, or the BRAKE command for manually toggling the output, both in
the Soloist help.
See Section 4.2.6. in Chapter 4, for more information on using the brake output.
See Section 3.3. for the J103 mating connector part number.
