Ethernet Communication Specifications
The PORT1 and PORT2 (RJ45) Ethernet connectors are provided for
communication with the Logix 5000® controller.
Motor Brake Circuit
The brake option is a spring-set holding brake that releases when voltage is
applied to the brake coil in the motor. The customer-supplied 24V power
supply drives the brake output through a solid-state relay. The solid-state brake
driver circuit provides the following:
• Brake current-overload protection
• Brake overvoltage protection
Two connections (BC-1 and BC-2) are required for the motor brake output.
Connections are rated for 2.0 A @ +24V (refer to Figure 35
).
Figure 35 - Motor Brake Circuit
Control of the solid-state relay to release the motor brake is configurable in the
Logix Designer application (refer to Configure SPM Motor Closed-loop
Control Axis Properties beginning on page 127). An active signal releases the
motor brake. Turn-on and turn-off delays are specified by the
MechanicalBrakeEngageDelay and MechanicalBrakeReleaseDelay settings.
Attribute Value
Communication
The drive auto-negotiates speed and duplex modes. These modes can
be forced through the Logix Designer application. 100BASE-TX, full-
duplex is recommended for maximum performance.
