Product Details

64WKS-M240/50-RLG Product Description

The Kollmorgen 64WKS-M240/50-RLG is a high-performance BDS-series servo drive engineered for energy-conscious industrial environments. Designed to deliver precise motor control with minimal power waste, this unit integrates seamlessly into smart production lines where load management, drive efficiency, and thermal stability are critical operational priorities. Whether deployed in continuous-duty machining centres, automated assembly systems, or high-cycle packaging lines, the 64WKS-M240/50-RLG provides the closed-loop servo authority needed to reduce idle-state energy draw and optimise per-cycle power consumption.

In a fully integrated smart factory architecture, the Kollmorgen 64WKS-M240/50-RLG operates as the precision motion authority within a layered energy management stack. At the field level, it receives velocity and torque commands from a Kollmorgen AKD series motion controller or a compatible PLC platform such as a Siemens S7-1500 or Allen-Bradley ControlLogix, translating digital set-points into tightly regulated motor shaft output with sub-millisecond response latency.

Power quality upstream is maintained by a Kollmorgen BDS-series regenerative power supply, which captures braking energy from deceleration events and feeds it back into the DC bus — directly reducing net energy consumption during high-cycle operations. Paired with a Schneider Electric PowerLogic PM8000 power monitoring module, plant engineers gain real-time visibility into per-drive energy consumption, power factor, and harmonic distortion, enabling data-driven load balancing across multiple servo axes.

On the feedback side, the RLG resolver interface of the 64WKS-M240/50-RLG connects directly to Kollmorgen Goldline or AKM series servo motors, providing absolute position data without battery backup requirements — a meaningful reliability advantage in 24/7 production environments. I/O coordination is handled through a Beckhoff EL series EtherCAT I/O terminal or equivalent distributed I/O rack, allowing the drive's enable, fault, and ready signals to be mapped into the plant-wide control topology without additional signal conditioning hardware.

For thermal load management, the drive's internal temperature monitoring works in conjunction with Pico Technology TC-08 thermocouple data loggers or equivalent industrial temperature sensors mounted on the drive cabinet, feeding thermal trend data to the SCADA layer. This allows predictive maintenance algorithms running on a Wonderware System Platform SCADA or Ignition by Inductive Automation to flag thermal anomalies before they escalate into unplanned downtime events.

HMI visualisation of drive status, energy consumption trends, and fault history is typically delivered through a Siemens SIMATIC HMI TP1200 Comfort or equivalent panel, giving operators a single-pane view of servo axis health without requiring access to the drive's local keypad. Communication between the drive, controller, and SCADA is bridged via a Moxa NPort 5650 serial device server where legacy RS-485 connectivity is required, or directly over EtherCAT/PROFINET where the control platform supports it natively.

The Kollmorgen 64WKS-M240/50-RLG contributes to factory-wide energy optimisation through several complementary mechanisms. Its closed-loop torque control eliminates the over-current conditions common in open-loop drive systems, reducing resistive heating in motor windings and extending motor insulation life — both of which translate directly into lower long-term energy and maintenance costs.

Dynamic load adaptation means the drive continuously adjusts output current to match actual mechanical load demand rather than running at a fixed power level. In applications with variable cycle loads — such as pick-and-place robots, servo-driven conveyors, or CNC spindle axes — this adaptive behaviour can reduce average power draw by 15–30% compared to legacy variable-speed drives operating without closed-loop feedback.

Regenerative braking capability allows kinetic energy from decelerating loads to be recovered and returned to the shared DC bus, where it can be consumed by other axes accelerating simultaneously. In multi-axis gantry systems or coordinated servo presses, this energy exchange between axes can meaningfully reduce peak demand charges and smooth the plant's overall power consumption profile.

From a production line rhythm perspective, the drive's high bandwidth current loop ensures that servo axes track their motion profiles with minimal following error, reducing the need for conservative speed de-rating that operators often apply to compensate for drive instability. Tighter motion tracking means faster, more repeatable cycle times — directly improving OEE (Overall Equipment Effectiveness) without increasing installed power capacity.

Predictive maintenance integration is supported through the drive's fault log and status output signals, which can be polled by the PLC or SCADA system to track cumulative run hours, fault frequency, and thermal headroom. This data feeds condition-based maintenance workflows, reducing unplanned downtime and the energy waste associated with emergency restart procedures and production catch-up cycles.

All units supplied by NANKMOS are drawn from verified surplus inventory, subjected to functional load testing prior to dispatch, and covered by a 12-Month Warranty. In-stock units are available for same-week shipment, minimising production line downtime during unplanned drive replacement scenarios.

Q1: What energy savings can I realistically expect from the Kollmorgen 64WKS-M240/50-RLG compared to a standard VFD? In closed-loop servo applications, the 64WKS-M240/50-RLG typically delivers 15–30% lower average power consumption versus open-loop variable-frequency drives on the same mechanical load, primarily through dynamic current regulation and regenerative braking. Actual savings depend on duty cycle, load profile, and the number of axes sharing a common DC bus.

Q2: Which PLC and motion controller platforms are compatible with this drive? The drive accepts ±10 V analogue velocity commands and step/direction inputs, making it compatible with most industrial PLC platforms including Siemens S7 series, Allen-Bradley ControlLogix/CompactLogix, Mitsubishi MELSEC, and Omron NJ/NX series. For networked motion, integration via a Kollmorgen AKD motion controller or a third-party EtherCAT master is recommended.

Q3: Can this drive replace an existing BDS-series unit without mechanical or wiring changes? Yes — the 64WKS-M240/50-RLG is a direct form-fit-function replacement for other Kollmorgen BDS-series drives of equivalent current rating. Resolver wiring, power terminals, and control connector pinouts are consistent across the BDS family. Verify firmware revision compatibility with your motion controller before commissioning.

Q4: What does the 12-Month Warranty cover, and how is the unit tested before shipment? Every unit undergoes functional load testing under representative operating conditions prior to dispatch. The 12-Month Warranty covers defects in materials and workmanship under normal industrial operating conditions. NANKMOS maintains in-stock inventory of the 64WKS-M240/50-RLG to support rapid replacement logistics. Contact [email protected] or +86 18359268345 for warranty claims or pre-shipment test reports.
