Product Overview

Kollmorgen AKD-P00306-NBEC-0000 Replacement for AKD Series: Seamless Transition & Legacy System Compatibility

The Kollmorgen AKD-P00306-NBEC-0000 is a 3A continuous-current EtherCAT servo drive from the industry-proven AKD Series, designed for high-precision motion control in demanding industrial automation environments. Whether you are retiring an aging servo system, replacing a failed unit on a production line, or executing a planned modernization of your machine control architecture, this drive delivers a verified drop-in upgrade path with minimal engineering overhead.

Many facilities running legacy Kollmorgen S200, S300, or earlier AKD variants are now facing end-of-life support challenges. The AKD-P00306-NBEC-0000 provides a direct migration target: it retains the same 24 VDC logic supply, identical STO (Safe Torque Off) wiring topology, and EtherCAT fieldbus interface that integrates natively with Beckhoff TwinCAT, Omron Sysmac, and other EtherCAT master controllers already deployed in your cabinet. Existing motor feedback cables—whether resolver, SFD (Smart Feedback Device), or EnDat 2.2—are supported without rewiring, dramatically reducing retrofit labor time and the risk of wiring errors during changeover.

For sites migrating from analog ±10 V velocity command architectures to digital fieldbus control, the AKD-P00306-NBEC-0000 supports both modes simultaneously during commissioning, allowing engineers to validate motion profiles in WorkBench software before cutting over to full EtherCAT cyclic synchronous position (CSP) or velocity (CSV) mode. This dual-mode capability is particularly valuable when upgrading multi-axis gantry systems or coordinated conveyor lines where staged cutover is operationally necessary.

In retrofit projects involving Kollmorgen AKM servo motors—such as the AKM21, AKM31, or AKM52 families—the AKD-P00306-NBEC-0000 auto-identifies motor parameters via the SFD interface, eliminating manual motor commissioning steps that were required with older drive generations. When paired with the AKD-EBUS EtherCAT expansion module or integrated into a multi-axis AKD PDMM (Programmable Drive Multi-axis Master) topology, the drive participates in distributed motion coordination without requiring a separate PLC for axis management on smaller machine cells.

Cabinet integration is straightforward: the AKD-P00306-NBEC-0000 occupies a standard 40 mm width DIN-rail or panel-mount footprint, compatible with existing AKD Series cutouts. The 120/240 VAC single-phase or three-phase AC input (model-dependent) connects to the same terminal block positions as predecessor units. For installations using a shared DC bus architecture with a Kollmorgen AKD-REGEN regeneration resistor or AKD-DCBUS common bus supply, the P00306 variant integrates without bus topology changes.

Communication and network integration is handled via the onboard EtherCAT port, supporting CoE (CANopen over EtherCAT) object dictionary access for parameter backup, restore, and remote diagnostics. Existing EtherCAT network segments—including those running Kollmorgen AKD2G drives, Beckhoff EK1100 couplers, or third-party EtherCAT I/O terminals—accept the AKD-P00306-NBEC-0000 as a standard slave node without topology reconfiguration. EEPROM-based parameter storage ensures drive configuration survives power cycling and simplifies spare-unit pre-configuration before field deployment.

For facilities managing multi-vendor control cabinets that also include Siemens SINAMICS or Allen-Bradley Kinetix servo drives on adjacent axes, the AKD-P00306-NBEC-0000 operates independently on its EtherCAT segment without cross-protocol interference, preserving existing PLC program logic on the master controller. Safety wiring for STO inputs follows IEC 62061 SIL 2 / PLd requirements, compatible with existing safety relay modules already installed in the cabinet.

Seamless Upgrade Solutions

A successful AKD-P00306-NBEC-0000 retrofit rarely involves the drive alone. In practice, the migration touches several adjacent components that must be verified or replaced in parallel. The AKD WorkBench USB programming cable (Kollmorgen part AKD-CABLE-USB) is the first tool required on-site for parameter backup of the outgoing drive and initial commissioning of the replacement unit. For multi-axis systems, the AKD-EBUS EtherCAT expansion bus connector ensures the new drive integrates into the existing daisy-chain topology without segment interruption.

When the retrofit involves replacing the motor as well as the drive, Kollmorgen AKM Series servo motors—particularly the AKM21E, AKM31E, and AKM52G variants—are the natural pairing for the P00306 current rating, with SFD feedback that enables plug-and-play auto-identification. If the existing motor is retained but the feedback device is aging, a Kollmorgen SFD feedback module replacement restores auto-ID capability without full motor replacement.

On the power side, facilities using a shared DC bus should verify the Kollmorgen AKD-REGEN external regeneration resistor rating against the updated duty cycle of the modernized axis. For cabinet builds that include Beckhoff EK1100 EtherCAT couplers and EL1008 / EL2008 digital I/O terminals, the AKD-P00306-NBEC-0000 joins the same EtherCAT segment without additional configuration. Where analog I/O bridging is still required during a phased migration, a Beckhoff EL3062 analog input terminal or equivalent signal isolator can translate legacy ±10 V command signals into the EtherCAT domain, preserving existing PLC output wiring while the fieldbus migration is completed axis by axis.

For HMI integration, existing Kollmorgen AKD PDMM or third-party HMI panels communicating via EtherCAT or Modbus TCP continue to operate without program changes, as the AKD-P00306-NBEC-0000 exposes the same CoE object dictionary structure as other AKD Series drives. Safety circuit integrity should be re-validated using the existing Pilz PNOZ or Sick safety relay modules already installed, confirming STO channel response times meet machine safety requirements post-retrofit.

Retrofit Guidance FAQ

Q: Can I reuse my existing motor power and feedback cables?
A: Yes. The AKD-P00306-NBEC-0000 uses the same X2 motor power connector pinout and X10 feedback connector as other AKD Series drives. Resolver and EnDat 2.2 cables from predecessor AKD units are directly compatible. SFD cables from AKM motors are plug-compatible. Verify cable shielding continuity before powering up.

Q: Do I need to rewrite my PLC program?
A: No, if your EtherCAT master already manages AKD Series drives. The AKD-P00306-NBEC-0000 presents the same ESI (EtherCAT Slave Information) file and CoE object dictionary as other AKD EtherCAT variants. Import the ESI file into TwinCAT or your EtherCAT configurator, map the existing PDO assignments, and the axis will appear identically to the replaced unit. Parameter files backed up from the outgoing drive can be restored via AKD WorkBench with minor version-check adjustments.

Q: What if my current system uses CANopen or analog command, not EtherCAT?
A: The NBEC suffix designates the EtherCAT variant. If your current master uses CANopen (NBCC suffix) or analog (NBAN suffix), you will need to either upgrade the master to EtherCAT or source the matching AKD variant. Contact TOPNLMS to confirm the correct suffix for your application before ordering.

Q: How much physical space does the drive require?
A: The AKD-P00306-NBEC-0000 has a 40 mm width profile, identical to all AKD Series drives in the 3A–6A current range. It mounts on standard 35 mm DIN rail or panel-mount with the same bolt pattern as predecessor units. No cabinet modification is required for a like-for-like swap.

Q: What is the commissioning procedure for a replacement unit?
A: (1) Back up parameters from the outgoing drive using AKD WorkBench. (2) Power down and disconnect the failed drive. (3) Install the AKD-P00306-NBEC-0000 using existing cable connections. (4) Connect USB programming cable and restore parameter file. (5) Verify motor auto-ID via SFD if applicable. (6) Enable drive and run motion test at reduced speed before returning to full production. Total commissioning time for an experienced technician is typically 30–90 minutes.

Q: Is the drive compatible with my existing safety circuit?
A: Yes. The STO (Safe Torque Off) inputs on the AKD-P00306-NBEC-0000 are dual-channel, 24 VDC, SIL 2 / PLd rated—identical to all AKD Series drives. Existing safety relay wiring and response-time validation data remain valid. Re-validate STO function after installation per your machine safety plan.
