Kollmorgen AKM23D-ANBNC-00 Retrofit-Ready Brushless Servo for AKM Series Control Systems
The Kollmorgen AKM23D-ANBNC-00 is a Frame 23 brushless AC servo motor engineered for seamless integration into legacy and modern AKM Series motion control architectures. With its IP65-rated enclosure, incremental encoder feedback, and compact footprint, this unit is purpose-built for retrofit projects where minimizing downtime and preserving existing wiring infrastructure are critical priorities. Whether you are replacing a failed unit on an aging production line or executing a planned upgrade of a multi-axis servo system, the AKM23D-ANBNC-00 delivers the dimensional and electrical compatibility required for a drop-in substitution without extensive mechanical rework.
This motor is fully compatible with Kollmorgen’s AKD servo drive platform, including the AKD-P00306-NAEC-0000 and AKD-P00606-NAEC-0000 drive variants commonly deployed in packaging, material handling, and precision assembly applications. When paired with an AKD drive, the motor’s feedback signals are automatically recognized through the drive’s SFD (Smart Feedback Device) interface, eliminating the need for manual encoder parameter configuration during commissioning. For legacy systems still running on the S200 or S300 servo drive series, compatibility verification against the motor’s resolver or encoder output type is recommended before installation.
In retrofit scenarios involving older Kollmorgen Goldline or BDS servo motor platforms, the AKM23D-ANBNC-00 provides a modern, higher-efficiency alternative with improved thermal management and reduced rotor inertia. Customers migrating from these discontinued product lines should verify shaft diameter, keyway dimensions, and flange bolt pattern against the existing mechanical coupling and gearbox interface. In most Frame 23 installations, the mounting footprint is interchangeable, but a review of the motor cable connector pinout — particularly the power connector (MS or M23 circular) and feedback connector — is essential to confirm wiring harness compatibility or determine whether a cable adapter is required.

Retrofit Planning for Existing Automation Systems
A successful retrofit begins well before the motor arrives on-site. For systems built around the Kollmorgen AKD servo drive and a Beckhoff CX or EK series EtherCAT coupler, the first step is to export and archive the existing WorkBench project file, including all axis parameters, tuning gains, and homing sequences. This backup ensures that if the new motor’s inertia or torque constant differs slightly from the failed unit, the original tuning baseline is preserved for comparison during re-commissioning.
For control cabinets integrating the AKM23D-ANBNC-00 alongside a Kollmorgen AKD-P multi-axis power supply or a shared DC bus configuration, verify that the bus capacitance and regenerative braking resistor sizing remain within specification after the motor swap. A motor with a different winding configuration — even within the same frame — can alter the system’s regenerative energy profile during deceleration cycles.
When the retrofit involves replacing multiple axes simultaneously, consider staging the replacement axis by axis rather than all at once. This approach allows the machine’s PLC program — whether running on a Beckhoff TwinCAT, Siemens S7, or Allen-Bradley ControlLogix platform — to be validated incrementally, reducing the risk of a full-system fault during the first power-up. Axis address assignments in the motion controller must be confirmed against the new drive’s node ID settings, particularly in EtherCAT topologies where the physical cable order determines the logical axis mapping.
Terminal wiring should be documented with photographs before disconnection. The motor power cable (U, V, W, PE) and feedback cable routing should be re-verified against the AKD installation manual to ensure correct phase sequence. Reversed phase wiring will cause the drive to fault immediately on enable; incorrect encoder wiring may result in runaway or oscillation. A Kollmorgen programming cable (USB-to-serial or direct USB, depending on the AKD variant) connected to a laptop running WorkBench is the standard tool for initial drive enable and motor identification.
For facilities managing spare parts inventory across multiple machine types, stocking the AKM23D-ANBNC-00 alongside compatible AKD-P00306 drives, M23 feedback cable assemblies, and a 24VDC control power supply module creates a self-contained retrofit kit that can be deployed rapidly when an unplanned failure occurs. Pre-tested and pre-configured drive-motor pairs further reduce mean time to repair (MTTR) in high-availability production environments.
Downtime Control During System Migration
Minimizing production downtime during a servo motor replacement requires a structured pre-work protocol. Before the maintenance window opens, the replacement AKM23D-ANBNC-00 should be bench-tested with a spare AKD drive using WorkBench’s motor identification routine. This confirms that the unit responds correctly to drive commands, that encoder feedback is clean, and that no mechanical defects are present — all before the unit enters the machine.
During the swap, the original PLC program logic should remain untouched. The motion controller’s axis configuration — including software travel limits, homing offsets, and velocity/acceleration profiles — should be exported and re-imported after the new drive is online to ensure parameter consistency. If the system uses an HMI panel (such as a Weintek, Siemens TP, or Proface unit) with axis status displays or jog controls, verify that the HMI’s communication link to the PLC or drive is re-established and that all screen tags referencing axis status bits are functioning correctly after the restart.
For EtherCAT-based systems, the network topology scan in TwinCAT or the equivalent tool should be run after reconnection to confirm that the new drive’s ESI (EtherCAT Slave Information) file matches the configured device in the project. A mismatch here will prevent the network from entering operational state. Having the correct ESI file pre-loaded on the engineering laptop before the maintenance window eliminates this potential delay.
All units supplied by SMARTNEXMSK undergo a pre-shipment functional test. Each AKM23D-ANBNC-00 is inspected for shaft runout, encoder signal integrity, winding resistance balance, and insulation resistance before dispatch. A 12-month warranty covers all manufacturing defects from the date of shipment, providing assurance for both planned retrofit projects and emergency replacement scenarios.
Retrofit Support FAQ
Q1: Is the AKM23D-ANBNC-00 a direct drop-in replacement for other AKM23 variants?
The AKM23D shares the same Frame 23 mounting footprint with other AKM23 variants (e.g., AKM23C, AKM23E), but winding characteristics, encoder type, and connector suffix differ between build codes. Always cross-reference the full part number suffix against the Kollmorgen AKM motor selection guide to confirm electrical compatibility with your existing drive and cable harness before ordering.
Q2: What commissioning steps are required after installation?
After mechanical installation and wiring, connect the AKD drive to a PC running Kollmorgen WorkBench software. Run the motor identification routine (Motor > Identify) to allow the drive to auto-detect the motor’s feedback device and winding parameters. Verify that the identified motor data matches the AKM23D-ANBNC-00 specifications. Re-run auto-tuning if the load inertia or coupling configuration has changed from the original installation.
Q3: Can this motor be used with non-Kollmorgen drives?
The AKM23D-ANBNC-00 can be operated with third-party servo drives that support incremental encoder feedback and accept standard sinusoidal or trapezoidal commutation, provided the drive’s current rating, voltage bus, and encoder input specifications are compatible. However, Kollmorgen’s SFD auto-identification feature is exclusive to AKD-series drives. Manual motor parameter entry will be required for non-Kollmorgen drives.
Q4: What does the 12-month warranty cover, and what is the return process?
The 12-month warranty covers manufacturing defects including winding failures, encoder malfunctions, bearing defects, and connector faults under normal operating conditions. It does not cover damage resulting from incorrect wiring, overvoltage, mechanical overload, or unauthorized disassembly. To initiate a warranty claim, contact SMARTNEXMSK with the order number, a description of the fault, and any available drive fault codes. Replacement or repair will be arranged after fault verification.
