Chapter 1 Replacement Considerations
Control of the solid-state relay to release the motor brake is configurable in the
Logix Designer application Refer to Kinetix 5300 Single-axis EtherNet/IP
Servo Drives User Manual, publication 2198-UM005
.
An active signal releases the motor brake. Turn-on and turn-off delays are
specified by the MechanicalBrakeEngageDelay and
MechanicalBrakeReleaseDelay settings.
Control and Auxiliary Power Specifications
The Kinetix 350 drives use a 24V DC logic power source for all drives (referred
to as control power). Table 18
shows the control power specifications for the
drives.
The Kinetix 5300 drives also require 24V DC input power for control circuitry.
IMPORTANT
Holding brakes that are available on Allen-Bradley® rotary motors are
designed to hold a motor shaft at 0 rpm for up to the rated brake-
holding torque, not to stop the rotation of the motor shaft, or be used
as a safety device.
You must command the servo drive to 0 rpm and engage the brake
only after verifying that the motor shaft is at 0 rpm.

IMPORTANT PELV rated power supplies must be used to energize external safety devices
connected to the Kinetix 5300 safety inputs.
The National Electrical Code and local electrical codes take precedence
over the values and methods provided. Implementation of these codes is
the responsibility of the machine builder.
