Kollmorgen AKD-P00306-NBEC-0069 Retrofit-Ready Servo Drive for AKD Series Control Systems
The Kollmorgen AKD-P00306-NBEC-0069 is a high-performance, retrofit-ready servo drive engineered for seamless integration into existing AKD Series automation platforms. Designed to replace discontinued or aging servo drive modules without requiring extensive rewiring or reprogramming, this unit delivers a smooth, low-risk upgrade path for engineers managing legacy motion control infrastructure. Whether you are modernizing a multi-axis CNC cell, upgrading a packaging line, or restoring a failed drive in a critical production environment, the AKD-P00306-NBEC-0069 provides the compatibility, reliability, and support documentation needed to minimize downtime and protect your existing investment.
Built around Kollmorgen’s proven AKD platform architecture, this servo drive supports EtherCAT fieldbus communication, enabling direct integration with existing EtherCAT master controllers without protocol conversion hardware. The drive is rated at 3A continuous output current and is compatible with the standard AKD Series 24VDC logic supply and AC mains input range, making it a drop-in candidate for most AKD-family installations. The NBEC firmware variant supports advanced motion profiles, electronic gearing, and cam table functions that are commonly used in legacy AKD applications, ensuring that existing PLC ladder logic and HMI screen mappings remain valid after the swap.

Retrofit Planning for Existing Automation Systems
Successful retrofit of the AKD-P00306-NBEC-0069 into an existing production line begins with a thorough pre-replacement audit. Engineers should first connect to the original drive using Kollmorgen WorkBench software and export the full parameter set, including motion task tables, digital I/O assignments, and fieldbus node configuration. This backup file serves as the baseline for programming the replacement unit and eliminates the need to reconstruct axis tuning from scratch.
On the power side, verify that the existing 24VDC logic supply — typically sourced from a Kollmorgen AKD-PSU or a third-party DIN-rail power supply — has sufficient current headroom to support the replacement drive during initialization. The AKD-P00306-NBEC-0069 draws approximately 0.5A from the 24V rail at idle, rising during brake control and I/O switching. If the cabinet also houses an AKD-PDMM (the integrated drive and machine controller variant), confirm that the shared DC bus voltage remains within specification after adding the new drive to the bus.
Terminal wiring on the AKD-P00306-NBEC-0069 follows the standard AKD Series connector map. The X2 motor power connector and X3 feedback connector are physically identical to earlier AKD-P variants, allowing direct transfer of existing motor cables without re-pinning. However, if the original installation used a Kollmorgen AKM Series servo motor with SFD3 smart feedback, confirm that the feedback cable shield is properly grounded at the drive end to prevent encoder noise issues after reinstallation.
For multi-axis systems using an AKD EtherCAT ring topology, the replacement drive must be assigned the same EtherCAT node address as the original unit. This is configured in WorkBench under the Network settings tab. If the system master is a Beckhoff TwinCAT controller or a Siemens S7 with EtherCAT master card, the ESI (EtherCAT Slave Information) file for the AKD-P00306-NBEC-0069 should be verified against the master’s device library to ensure the slave profile matches. In installations where the AKD drives share a backplane or are mounted in an AKD-RACK multi-axis chassis, confirm that the slot address and axis number assignments in the PLC program correspond to the physical drive position after reinstallation.
I/O expansion modules connected to the AKD’s X7 and X8 digital I/O terminals — such as external relay boards, safety relay modules, or Kollmorgen AKD-ADDON I/O expansion cards — should be disconnected and reconnected systematically, with each I/O point verified against the original wiring diagram. If the system uses a Kollmorgen AKD-C central supply unit for shared DC bus operation, ensure the bus capacitor pre-charge sequence is completed before enabling the replacement drive to avoid inrush current faults.
HMI screens built on platforms such as Weintek, Proface, or Siemens TP series panels that display axis status, drive fault codes, or position feedback from the AKD drive will continue to function without modification, provided the EtherCAT node address and CoE object mapping remain unchanged. If the HMI communicates via OPC-UA or Modbus TCP through a gateway, verify the gateway’s tag database still maps correctly to the new drive’s object dictionary after firmware initialization.
Downtime Control During System Migration
Minimizing production downtime during an AKD servo drive replacement requires a structured hot-swap preparation protocol. Before powering down the machine, use WorkBench to capture a live snapshot of the drive’s current fault history, operating hours, and tuning parameters. This data provides a reference baseline and can accelerate post-installation commissioning by confirming that the replacement drive’s behavior matches the original.
Schedule the physical swap during a planned maintenance window and pre-stage the AKD-P00306-NBEC-0069 on a bench test fixture if possible. Load the exported parameter file into the new drive, assign the correct node address, and verify basic I/O response before installing the unit in the cabinet. This pre-commissioning step can reduce in-cabinet installation time to under 30 minutes for experienced technicians.
During reinstallation, follow a structured power-up sequence: apply 24VDC logic power first, confirm EtherCAT link establishment with the master controller, then enable AC mains power. Monitor the drive’s status LEDs and WorkBench online diagnostics for any fault codes related to feedback signal loss, overcurrent, or bus voltage deviation. If the system uses a Kollmorgen AKD-PDMM as the motion controller, re-download the machine program after confirming the drive is online to ensure the axis object bindings are refreshed.
Protecting the original program logic is critical. Never overwrite the PLC or motion controller program during a drive swap — the axis configuration in the controller should remain intact, with only the drive-side parameters being updated. If the system uses a Kollmorgen KAS (Kollmorgen Automation Suite) project, the drive replacement is handled at the hardware configuration level without modifying the application logic, preserving all cam profiles, electronic gearing ratios, and sequence programs developed for the original installation.
Retrofit Support FAQ
Q1: Is the AKD-P00306-NBEC-0069 a direct drop-in replacement for other AKD-P 3A variants?
Yes, the AKD-P00306-NBEC-0069 is mechanically and electrically compatible with other AKD-P Series 3A drives sharing the same connector layout. The NBEC firmware variant supports the same CoE object dictionary as standard AKD-P units. However, always export and import the parameter file from the original drive to ensure motion task tables, I/O assignments, and tuning gains are correctly transferred to the replacement unit.
Q2: What commissioning steps are required after installation?
After physical installation and wiring verification, connect to the drive via WorkBench software, import the saved parameter file, and assign the correct EtherCAT node address. Perform a feedback signal check to confirm encoder communication, then run a low-speed jog test to verify motor direction and velocity response before returning the axis to automatic mode. Document all commissioning steps and fault log readings for maintenance records.
Q3: Can the existing motor cables and feedback cables be reused?
In most cases, yes. The AKD-P00306-NBEC-0069 uses the same X2 and X3 connector pinout as standard AKD-P Series drives, allowing direct reuse of existing Kollmorgen motor power and feedback cables. Inspect cable insulation and connector contacts for wear before reinstallation, particularly in high-cycle or high-temperature environments. Replace any cables showing signs of insulation damage or connector corrosion to prevent intermittent feedback faults after commissioning.
Q4: What does the 12-month warranty cover?
Every AKD-P00306-NBEC-0069 unit shipped by SMARTNEXMSK is covered by a 12-month warranty from the date of shipment. The warranty covers manufacturing defects, component failures under normal operating conditions, and functional performance against published specifications.
