2.6. Brake Power Supply Connector (TB202)
TB202 is the power supply connection to the onboard solid state brake control relay.The relay can be used to
automatically control a fail-safe brake on a vertical axis. It can also be used as a general purpose output.
The brake is typically wired directly to the Motor Feedback connector and the brake power supply is
connected to TB202 (
). The brake can also be connected in series with the Brake Power Supply
and interlocked using Motor Feedback brake pins (
). A varistor must be connected across the
brake to minimize high voltage transients.
The brake output can be software configured; refer to the Soloist Help file for more information (see topics for
the EnableBrakeControl parameter and the BRAKE command).
When TB202 is used to power the solid state brake control relay, the mechanical brake control relay present
on the I/O board should not be used.
N O T E :
The brake power supply must be externally fused.
The user must verify that the brake power requirements are within the specifications of the brake control
relay.
