Power and Relay
Specifications

This section provides a description of the Kinetix 6000 brake relay (BC), input
power (IPD), motor power (MP), and control power (CPD) connectors.

Motor/Resistive Brake Relay

Series C brake circuits use solid-state relays. Series A and B drive modules used
mechanical relays. The solid-state brake driver circuit provides the following:

Brake thermal overload protection
Brake current overload protection
Brake short circuit protection

Two connections are required for the (customer-supplied) motor/resistive brake
input power (BC-3 and BC-4) and two connections each for the motor and
resistive brake output, as shown in

Figure 33

. Wiring is consistent with all series

releases. Connections are rated for +24V and current as shown in

Table 42

.

An active signal releases the motor brake (BC-5 and BC-6). The brake signal
turn-on and turn-off delays are specified by the brake active delay and brake
inactive delay (configurable in the Logix Designer application). Refer to the Axis
Module/Rotary Motor Wiring Examples b
eginning on

page 196

and the

Controlling a Brake Example on

page 211

for wiring examples.

The resistive brake relay (BC-1 and BC-2) controls the resistive brake module
(RBM) contactor. The RBM module is wired between the drive and motor by
using an internal contactor to switch the motor between the drive and a resistive
load. The RBM module contact delay is the time it takes to fully close the
contactor across the motor power input lines, and must be configured in the
software. Refer to RBM Module Interconnect Diagrams beginning on

page 265

for wiring examples.
