AR-20xE & AR30xE Control Connector On the AR-20xE & AR 30xE models, the Control connector serves for three
connections: an external power dump resistor (EXTERNAL REGEN), a control
power circuit (CONTROL INPUT POWER), and a safety brake relay (BRAKE
RELAY). The connector is an eight-position non-removable screw terminal.
Specifications for the connector follow in this section.
The Control connector has a factory-installed link between RINT and R− for an
internal regeneration resistor, which provides thermal protection. For more
information, see “Regeneration Protection” on page 54. For information on
additional connections, see “Control Power Supply” on page 46 and “Brake
Relay (Optional)” on page 50.
