KOLLMORGEN SERVOSTAR 614 Replacement for SERVOSTAR 600

Product Overview

KOLLMORGEN SERVOSTAR 614 Replacement for SERVOSTAR 600: Smooth Transition & Legacy System Compatibility

When your existing KOLLMORGEN SERVOSTAR 600 Series installation reaches end-of-life or a unit fails in the field, unplanned downtime is the costliest outcome in any automated production environment. The SERVOSTAR 614 (3×230–480V, 10KVA, 14A) is a direct-fit replacement and upgrade solution engineered to restore your servo axis with minimal re-engineering. Whether you are retiring a legacy SERVOSTAR 601, SERVOSTAR 604, or SERVOSTAR 608 from an existing multi-axis cabinet, or migrating an entire motion control architecture to a modernized platform, the SERVOSTAR 614 is designed to slot into your existing infrastructure with the lowest possible disruption to wiring, programming, and commissioning schedules.

The SERVOSTAR 600 Series uses a standardized 24 VDC logic supply and a shared DC bus architecture, meaning the SERVOSTAR 614 can be integrated alongside other drives in the same cabinet without requiring a dedicated transformer or separate power conditioning. The drive accepts a wide input voltage range of 3×230–480V AC, making it compatible with both European 400V and North American 480V three-phase supplies — a critical advantage when the same machine platform is deployed across multiple facilities or geographies. The 14A continuous output current rating covers a broad range of KOLLMORGEN AKM Series and S Series servo motors, and the drive’s resolver and encoder feedback interfaces are backward-compatible with the feedback devices already installed on your existing motor shafts, eliminating the need for motor replacement in most retrofit scenarios.

From a communications standpoint, the SERVOSTAR 614 supports the SERCOS II fiber-optic fieldbus natively, and optional interface cards enable CANopen and PROFIBUS-DP connectivity. If your existing motion controller — such as a Siemens SINUMERIK, a Beckhoff TwinCAT system, or a Rockwell Automation ControlLogix platform — communicates with the legacy drive via one of these protocols, the replacement unit can be configured to match the same node address, baud rate, and cyclic data mapping, preserving your existing PLC program without modification. The SERVOSTAR 614’s parameter set is fully compatible with the KOLLMORGEN WorkBench commissioning software, allowing engineers to upload a saved parameter file from the failed unit and restore the axis configuration in minutes rather than hours.

Physical installation is equally straightforward. The SERVOSTAR 614 occupies the same DIN-rail or panel-mount footprint as other drives in the SERVOSTAR 600 family. The X1 mains connector, X2 motor power connector, X3 feedback connector, and X4 I/O connector pinouts are identical to those of the SERVOSTAR 601 through SERVOSTAR 616, so existing cable harnesses can be reconnected without modification. If your cabinet also houses a SERVOSTAR 616 or SERVOSTAR 620 on an adjacent axis, the shared DC bus link connector (X9) mates directly, maintaining the regenerative energy-sharing topology that reduces overall cabinet heat dissipation and energy consumption.

Seamless Upgrade Solutions

A complete SERVOSTAR 614 retrofit typically involves more than the drive itself. During the migration process, engineers commonly address the following companion components to ensure system integrity. The SERVOSTAR 616 and SERVOSTAR 620 are frequently upgraded in the same cabinet pass, sharing the DC bus and reducing the number of separate mains fuses required. The KOLLMORGEN AKM Series servo motors — particularly the AKM42, AKM52, and AKM63 frames — are the most common motor partners for the SERVOSTAR 614 in the 10KVA power class, and their resolver feedback cables connect directly to the X3 port without adapters.

For multi-axis systems, the SERVOSTAR 600 Series power supply module (regenerative or non-regenerative) feeds the shared DC bus; verifying its capacity against the aggregate peak current demand of all connected drives — including the replacement SERVOSTAR 614 — is a standard commissioning step. The KOLLMORGEN S700 Series drives are the recommended long-term migration target for applications requiring EtherCAT or SynqNet connectivity, and the SERVOSTAR 614 can serve as an interim replacement while the broader system architecture is modernized. Fieldbus connectivity is typically managed through a PROFIBUS-DP interface card (OPT-2-030) or a CANopen interface card (OPT-2-020) inserted into the drive’s option slot — both are available as separate line items and should be ordered alongside the drive if the existing unit carried one.

Cabinet wiring integrity is often addressed during a drive swap: KOLLMORGEN motor power cables (pre-assembled with CE-compliant shielding and the correct X2 connector) and feedback cables (resolver or encoder, with the X3 sub-D connector) are available as matched accessories. A KOLLMORGEN programming cable (USB-to-RS232 adapter) is required for initial WorkBench connection if the cabinet does not have a permanent PC interface. Finally, if the application involves a safety function such as Safe Torque Off (STO), the STO wiring harness and associated safety relay module should be verified against the SERVOSTAR 614’s X4 I/O pinout before energizing the system.

Retrofit Guidance FAQ

Q: Can I reuse my existing motor power and feedback cables?
A: Yes. The SERVOSTAR 614 uses the same X2 motor power connector and X3 feedback connector pinout as all SERVOSTAR 600 Series drives. Existing cables rated for the original drive’s current class are compatible, provided they are in good condition and correctly shielded.

Q: Do I need to rewrite my PLC program after replacing the drive?
A: No, in most cases. If the replacement drive is configured with the same fieldbus node address, baud rate, and cyclic PDO mapping as the original unit, the upstream PLC or motion controller will communicate with it transparently. Parameter files saved from the original drive can be loaded via WorkBench to restore axis tuning and I/O assignments.

Q: Will the SERVOSTAR 614 fit in the same cabinet slot?
A: Yes. The SERVOSTAR 614 shares the same mechanical envelope as other SERVOSTAR 600 drives. Mounting hole positions, DIN-rail clip geometry, and connector locations are identical, so no cabinet modification is required.

Q: What fieldbus protocols are supported?
A: The SERVOSTAR 614 natively supports SERCOS II via fiber-optic interface. CANopen and PROFIBUS-DP are available via plug-in option cards. RS-232 and RS-485 serial interfaces are available on the X6 connector for WorkBench commissioning and parameter backup.

Q: How do I handle the Safe Torque Off (STO) function during replacement?
A: The STO input on the SERVOSTAR 614 is wired via the X4 I/O connector. Verify that the safety relay output voltage and contact configuration match the drive’s STO input specification (24 VDC, active-high) before commissioning. Functional safety validation should be performed after any drive replacement in a safety-rated application.
