Matched axis capacity
The smaller and larger power stages preserve the same control sequence while accommodating different motor-current demand.

230 V-class servo control · scalable axis current · separated control and motor paths
Product Details
Allen-Bradley 2071-A10 / 2071-A15 are Kinetix 3 component servo drives that accept a 230 V-class three-phase supply and close the motor-control loop through dedicated command, encoder, and motor-power interfaces. The paired catalog numbers share the same control architecture while 2071-A15 extends the current and output capability above 2071-A10.
At the cabinet interface, 2071-A10 / 2071-A15 place mains and motor conductors on power terminals while CN1 carries command and I/O signals, CN2 returns motor feedback, and the serial connector supports commissioning communication. This separation lets the drive process position or velocity commands without routing low-level feedback through the switched motor-power path.

System Integration — Connector and Signal Paths
The 2071-A10 / 2071-A15 connector layout separates power conversion from command, feedback, and commissioning circuits.
Command and I/O
Pulse, analog, enable, limit, and status signals enter the drive through the control connector.
Motor feedback
Encoder information returns on a dedicated low-level path so the regulator can compare commanded and measured motion.
Mains and motor terminals
Incoming three-phase power is rectified inside the drive and controlled output leaves on the motor terminals.
Selection and Use Questions
What changes when selecting 2071-A10 / 2071-A15 for the same Kinetix 3 control scheme?
2071-A10 / 2071-A15 keep the same control interfaces, but the A15 power stage provides the higher continuous and peak current. Motor current and mechanical demand therefore decide the selection, not connector appearance alone.
Why can 2071-A10 / 2071-A15 power up yet fail to produce motor torque?
For 2071-A10 / 2071-A15, confirm the three-phase mains, drive-enable input, active alarm, motor-power terminals, and encoder feedback. Communication or display activity does not by itself prove that the power stage is enabled.
Where should troubleshooting begin when 2071-A10 / 2071-A15 report a feedback alarm?
On 2071-A10 / 2071-A15, inspect the CN2 encoder connector, cable continuity, shield termination, and the configured motor feedback type before changing power wiring.
How should control and motor wiring be routed around 2071-A10 / 2071-A15?
Route CN1, CN2, and serial wiring for 2071-A10 / 2071-A15 apart from mains and motor conductors, crossing power wiring at right angles where separation cannot be maintained.
What must be preserved when quoting 2071-A10 / 2071-A15?
Keep the complete 2071-A10 / 2071-A15 catalog numbers with the motor, supply class, connector requirements, and axis-current demand so the two power ratings are not treated as interchangeable.
Can 2071-A10 / 2071-A15 share one protection size simply because the housings match?
No. 2071-A10 / 2071-A15 have different input and output current demands; branch protection and upstream devices must be checked for the selected catalog number and installation.
