3.2. Brake Relay Connector (TB201)
TB201 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 TB201 (shown in
Figure 3-2 ). The brake may also be connected in series with the Brake Power
Supply and interlocked using Motor Feedback brake pins ( Figure 3-3 ). A varistor must be connected across
the brake to minimize high voltage transients.
The brake output can be software configured; refer to the A3200 Help file for more information (see topics for
the EnableBrakeControl parameter and the BRAKE command).
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.
