3.4 PA-4 Connectors

The connectors on the PA-4 EMC box are described below.

Arm Power/Signal Connector

The circular Arm Power/Signal connector on the PA-4 shipped with Viper s650/s850

(with PA-4) and Viper s1300 systems carries all the motor power and encoder feedback

connections between the controller and the robot. See Figure 3-1 on page 26 and Figure

3-2 on page 27.

Power and Encoder Connectors

The two rectangular connections on the Viper s1700 serve the same purpose as the Arm

Power/Signal connector on the PA-4 shipped with Viper s650/s850 (with PA-4) and

Viper s1300 systems. See Figure 3-3 on page 28. However, the Viper s1700 uses two

cables. The Power connector carries motor power connections and the Encoder connector

carries encoder feedback connections.

External Brake Connector

The External Brake connector’s wire list and pinouts are shown below. See Figure 3-1 on

page 26 for the connector’s location.

This connector provides a low-side driver output that is suitable for driving a 24 V device,

such as a solenoid or pneumatic valve. This driver is internally activated in response to a

J1 brake release command. The solenoid or valve should be connected between pin 1 (24 V

source) and pin 2 (switched GND return). This output is capable of driving up to 10 W

(400 mA @ 24 V). Pins 3 and 4 are reserved for future functionality.
