KOLLMORGEN LY-S600-OZ EtherCAT Servo Drive for S600 Systems

KOLLMORGEN LY-S600-OZ: Industrial Data Link and Smart Factory Connectivity for S600 Motion Systems

In modern smart factory environments, the ability to move real-time data seamlessly across every layer of the automation hierarchy — from field-level sensors and actuators to SCADA dashboards and enterprise MES platforms — defines the competitive edge of a production facility. The KOLLMORGEN LY-S600-OZ EtherCAT servo drive is engineered precisely for this role. As a high-performance network-capable motion controller within the S600 Goldline series, it serves as a critical node in the industrial data chain, bridging the gap between precision motion execution and plant-wide digital intelligence.

The LY-S600-OZ is not simply a servo amplifier — it is an intelligent network participant. Its native EtherCAT interface enables deterministic, real-time communication at cycle times as low as 125 µs, making it fully compatible with high-speed motion coordination architectures where synchronization between multiple axes is non-negotiable. Whether deployed in a multi-axis gantry system, a high-throughput packaging line, or a precision CNC machining center, the LY-S600-OZ maintains its position in the data flow with zero compromise on latency or reliability.

Compatibility & Integration Notes

Connected Automation Data Flow

The LY-S600-OZ operates at the intersection of motion control and industrial networking. In a typical smart factory deployment, the data flow begins at the field level: KOLLMORGEN AKM series servo motors equipped with EnDat 2.2 encoders feed high-resolution position and velocity data back to the LY-S600-OZ in real time. This feedback loop is processed locally within the drive’s DSP core, while the resulting motion state data is simultaneously transmitted upstream via EtherCAT to the motion controller — typically a KOLLMORGEN AKD-PDMM or a third-party EtherCAT master such as a Beckhoff CX series IPC or a Siemens S7-1500T with EtherCAT CM.

At the network layer, the EtherCAT protocol ensures that all axis data — including actual position, following error, drive status, and fault codes — is available to the SCADA system or HMI within a single bus cycle. Industrial HMI platforms such as the Weintek cMT series or Siemens TP1200 Comfort panels can display live drive diagnostics, axis position trends, and alarm histories without requiring additional protocol gateways. This direct visibility into drive-level data dramatically reduces the time required for fault diagnosis and process optimization.

For facilities running mixed-protocol environments — where legacy PROFIBUS DP or Modbus RTU devices coexist with modern EtherCAT nodes — an EtherCAT-to-PROFIBUS gateway such as the HMS Anybus X-gateway can be inserted between the LY-S600-OZ network segment and the legacy field bus, preserving investment in existing instrumentation while enabling the LY-S600-OZ to participate in the broader plant network. Similarly, remote I/O modules such as the Beckhoff EK1100 EtherCAT coupler with EL series I/O terminals can be daisy-chained on the same EtherCAT segment, allowing the motion controller to read digital and analog process signals — pressure transducers, flow meters, proximity sensors — alongside servo axis data in a unified real-time network.

Power distribution to the LY-S600-OZ is typically managed through a KOLLMORGEN S600 DC bus power supply or a compatible three-phase regenerative supply, with DC bus sharing between multiple S600 drives reducing overall energy consumption and simplifying cabinet wiring. The drive’s STO input connects directly to a safety relay module — such as the Pilz PNOZ X or Phoenix Contact PSR series — ensuring that the safe torque off function is integrated into the machine’s safety circuit without requiring additional hardware interlocks.

At the edge computing layer, an industrial edge gateway — such as the Siemens SINEMA Remote Connect or a Moxa UC series IPC — can aggregate EtherCAT data from multiple LY-S600-OZ drives and forward it to cloud-based analytics platforms or MES systems via OPC UA or MQTT. This enables predictive maintenance workflows where drive temperature trends, load current history, and encoder health data are analyzed over time to predict bearing wear or winding degradation before a failure occurs.

Solving Data Isolation in Industrial Sites

One of the most persistent challenges in industrial automation is the fragmentation of data across incompatible protocols and isolated control islands. A facility may have servo drives communicating over EtherCAT, variable frequency drives on PROFINET, PLCs on Modbus TCP, and safety systems on PROFIsafe — each generating valuable process data that never reaches the operators or engineers who need it most.

The KOLLMORGEN LY-S600-OZ addresses this challenge at the drive level by providing a standards-compliant EtherCAT interface that integrates natively with any EtherCAT master, regardless of brand. This eliminates the need for proprietary communication cards or vendor-specific software drivers, reducing integration complexity and shortening commissioning time. Engineers can use standard EtherCAT configuration tools — such as TwinCAT 3, CODESYS, or Sysmac Studio — to map drive process data objects (PDOs) directly into the PLC program, making axis status, fault codes, and motion parameters available as standard PLC variables accessible to HMI, SCADA, and MES layers.

For remote monitoring and diagnostics, the LY-S600-OZ supports parameter access via EtherCAT SDO (Service Data Object) communication, allowing remote engineers to read and write drive parameters — including current limits, ramp rates, and encoder offset values — without physical access to the control cabinet. This capability is particularly valuable in geographically distributed facilities such as water treatment plants, mining operations, and offshore platforms where on-site service visits are costly and time-consuming.

Production line transparency is further enhanced by the drive’s comprehensive fault logging capability. Every fault event — overcurrent, encoder error, STO activation, communication timeout — is timestamped and stored in the drive’s internal event log, which can be retrieved via EtherCAT SDO or the drive’s USB service interface. This data, when correlated with SCADA alarm records and production batch logs, provides a complete picture of machine behavior over time, enabling root cause analysis and continuous improvement initiatives.

Industrial Connectivity FAQ

Q1: What is the EtherCAT cycle time of the LY-S600-OZ, and is it suitable for high-speed multi-axis synchronization?
The LY-S600-OZ supports EtherCAT cycle times as low as 125 µs, making it fully suitable for high-speed multi-axis synchronization applications including electronic gearing, cam profiling, and coordinated pick-and-place motion. All axes on the same EtherCAT segment are synchronized to the distributed clock (DC) with sub-microsecond jitter, ensuring consistent motion performance across the entire machine.

Q2: Is the LY-S600-OZ compatible with third-party EtherCAT masters and motion controllers?
Yes. The LY-S600-OZ implements the CiA 402 drive profile over EtherCAT, which is supported by all major EtherCAT master platforms including Beckhoff TwinCAT, CODESYS-based controllers, Omron Sysmac, and Yaskawa MP3000 series. The drive’s ESI (EtherCAT Slave Information) file is available for import into any EtherCAT configuration tool, enabling rapid integration without custom programming.

Q3: How does the warranty terms confirmed during quotation apply, and what does pre-shipment testing cover?
Every LY-S600-OZ unit supplied by ZYPLC is covered by a warranty terms confirmed during quotation from the date of shipment. Pre-shipment testing includes power-on functional verification, EtherCAT communication handshake confirmation, STO input/output validation, and encoder feedback signal integrity check. Units that do not pass all test criteria are not shipped. Warranty claims are processed within 5 business days of fault confirmation.

Q4: Can the LY-S600-OZ be used in a network with both EtherCAT and legacy PROFIBUS devices?
Yes, through the use of an EtherCAT-to-PROFIBUS gateway. The LY-S600-OZ operates as a standard EtherCAT slave on the high-speed segment, while the gateway bridges data to the legacy PROFIBUS network. This architecture allows the LY-S600-OZ to coexist with older drives, sensors, and I/O modules without requiring a full network upgrade, protecting existing infrastructure investment while enabling smart factory connectivity.
