KOLLMORGEN P70360-SDN Replacement for P7000 Series

Product Overview

KOLLMORGEN P70360-SDN Replacement for P7000 Series: Seamless Transition & Legacy System Compatibility

The KOLLMORGEN P70360-SDN is a high-performance DeviceNet-enabled servo drive from the P7000 Series, designed for demanding motion control applications in industrial automation environments. As legacy servo systems age and original equipment manufacturers discontinue support for older drive platforms, facilities running KOLLMORGEN S700, AKD, or earlier Servostar 600 series drives face increasing pressure to source reliable replacement units or execute a controlled migration to a compatible successor. The P70360-SDN addresses this need directly — offering a drop-in upgrade path that preserves existing wiring infrastructure, DeviceNet network topology, and control cabinet space allocation.

For plants currently operating discontinued KOLLMORGEN Servostar 300 or Servostar 600 servo drives, the P70360-SDN provides a validated replacement route. The drive accepts standard resolver and encoder feedback signals, meaning existing motor cabling and feedback wiring from legacy KOLLMORGEN servo motors — including the AKM and TBM series — can typically be retained without modification. This dramatically reduces retrofit labor costs and minimizes the risk of wiring errors during changeover.

The P70360-SDN communicates natively over DeviceNet, a CAN-based fieldbus protocol widely deployed in automotive, packaging, and material handling systems. Facilities running Allen-Bradley (Rockwell Automation) ControlLogix or CompactLogix PLCs with 1756-DNB or 1769-SDN DeviceNet scanner modules will find the P70360-SDN integrates cleanly into existing network configurations. Node addressing and baud rate settings are preserved from prior drive configurations, allowing commissioning engineers to restore motion profiles with minimal reprogramming effort.

Physical installation is equally straightforward. The P7000 Series maintains a consistent DIN-rail and panel-mount footprint across its power range, so replacing a failed or end-of-life unit within an existing control cabinet requires no enclosure modification. The drive’s DC bus architecture supports shared bus configurations, enabling multi-axis systems — where a KOLLMORGEN P70530-SDN or P71000-SDN may be operating adjacent axes — to continue sharing regenerative energy without additional hardware changes.

For facilities executing a broader system modernization, the P70360-SDN can serve as an interim solution while the control architecture transitions from legacy DeviceNet to EtherNet/IP or PROFINET. During this transition period, the drive continues to operate under the existing DeviceNet master, while engineering teams validate new PLC logic and HMI screen updates on parallel test benches. This phased approach eliminates the need for a full production shutdown and allows incremental validation of each axis before cutover.

Power supply compatibility is another key consideration in servo drive replacement projects. The P70360-SDN operates from a standard three-phase AC input and includes an integrated EMC filter, reducing the need for external line filters in most cabinet configurations. Where existing installations include a KOLLMORGEN P7000 Series regenerative power supply or shared DC bus supply module, the P70360-SDN connects directly to the established DC bus rail, maintaining system energy efficiency and eliminating the need for individual braking resistors on each axis.

Commissioning the P70360-SDN in a replacement scenario is supported by KOLLMORGEN’s WorkBench software, which retains backward compatibility with parameter files exported from earlier P7000 drives. Engineers can import existing tuning parameters — including velocity loop gains, position loop bandwidth, and current limits — directly into the replacement unit, reducing auto-tuning time and accelerating return to production. For sites without on-site commissioning expertise, TOPNLMS provides pre-shipment parameter loading upon request.

Seamless Upgrade Solutions

A successful P70360-SDN retrofit rarely involves the drive alone. In most multi-axis control cabinets, the servo drive operates alongside a suite of supporting components that must be evaluated for compatibility during the upgrade process.

On the network side, the DeviceNet trunk cable and drop lines connecting the P70360-SDN to the PLC scanner — typically a 1756-DNB DeviceNet bridge module in a ControlLogix rack — should be inspected for termination resistance and node count compliance. If the existing network is operating near its 64-node limit, adding the replacement drive may require a network audit before commissioning.

For the motor feedback circuit, the existing resolver cable connecting the P70360-SDN to a KOLLMORGEN AKM servo motor or TBM torque motor can typically be reused. However, if the cable has been routed near high-voltage conductors without adequate shielding, replacing the feedback cable with a properly shielded assembly is recommended to prevent encoder noise faults during high-speed operation.

The DC bus supply architecture in P7000 Series systems often includes a dedicated KOLLMORGEN P7000 Series power supply module or regenerative supply unit. When replacing a single drive in a shared bus system, the bus capacitance and regenerative capacity of the existing supply should be verified against the new drive’s peak current demand. In systems where a KOLLMORGEN P70530-SDN or P71000-SDN operates on the same bus, the combined peak current draw must remain within the supply module’s rated output.

Control cabinet I/O wiring to the P70360-SDN’s digital and analog I/O terminals — used for enable signals, fault resets, speed references, and torque limits — follows the same terminal assignment as earlier P7000 drives. Terminal blocks and signal isolators already installed in the cabinet can be retained, reducing rewiring time to near zero in most cases. Where signal conditioning is required between the PLC analog output and the drive’s speed reference input, a DIN-rail mounted signal isolator or analog signal conditioner can be inserted without cabinet modification.

For facilities upgrading the HMI simultaneously, the existing operator panel or SCADA system communicating over DeviceNet or Modbus RTU can continue to monitor drive status parameters — including actual velocity, torque output, DC bus voltage, and fault codes — through the same network interface, provided the HMI tag database is updated to reflect the new drive’s object dictionary addresses.

Finally, programming cable and laptop-based commissioning tools should be verified before on-site work begins. KOLLMORGEN WorkBench connects to the P70360-SDN via a standard USB-to-serial adapter or direct USB port, depending on the drive revision. Having the correct cable and a licensed copy of WorkBench on-site before the maintenance window opens is essential to minimizing downtime during the drive swap.

Retrofit Guidance FAQ

Q: Can I reuse the existing DeviceNet wiring and node address when replacing with the P70360-SDN?
A: Yes. The P70360-SDN uses the same DeviceNet physical layer (CAN, 125/250/500 kbps) and supports the same node addressing range (0–63). The replacement drive can be configured to the same node address as the failed unit, allowing the PLC program to remain unchanged.

Q: Will my existing KOLLMORGEN AKM motor work with the P70360-SDN without rewiring?
A: In most cases, yes. The P70360-SDN supports resolver and incremental encoder feedback, which are standard on AKM and TBM series motors. Verify the motor’s feedback type and connector pinout against the drive’s feedback connector specification before installation.

Q: Do I need to retune the servo after replacing the drive?
A: If the original tuning parameters are available (exported from WorkBench or documented in the commissioning report), they can be imported directly into the replacement P70360-SDN. Minor fine-tuning may be required if the motor or mechanical load has changed, but a full auto-tune is typically not necessary.

Q: Is the P70360-SDN compatible with a shared DC bus system?
A: Yes. The P7000 Series is designed for shared DC bus operation. The replacement drive connects to the existing bus rail without additional hardware, provided the bus supply capacity is sufficient for the combined axis load.

Q: What physical space does the P70360-SDN require in the control cabinet?
A: The P70360-SDN maintains the standard P7000 Series panel-mount footprint. If replacing a same-series drive, no cabinet modification is required. Verify the mounting hole pattern and clearance requirements against the installation manual if replacing a drive from a different series.

Q: What communication protocols does the P70360-SDN support beyond DeviceNet?
A: The P70360-SDN is specifically configured for DeviceNet (SDN suffix). For EtherNet/IP or PROFINET connectivity, alternative P7000 variants with the appropriate communication option card are available. Contact TOPNLMS to confirm the correct variant for your network architecture.
