Atos Z-ME-KZ-PS Digital Position Controller

Product Details

Z-ME-KZ-PS Product Description

The ATOS Z-ME-KZ-PS is a closed-loop digital position controller engineered for the Z-ME hydraulic servo axis series, purpose-built to serve as a precision data node within modern smart factory architectures. As industrial plants transition from isolated machine control toward fully networked, data-driven production environments, the Z-ME-KZ-PS delivers the connectivity backbone that bridges field-level hydraulic actuation with upper-layer control and monitoring systems. Whether integrated into a multi-axis press line, a precision injection molding cell, or a heavy-duty material handling system, this controller ensures that every position command, feedback signal, and diagnostic event is captured, transmitted, and acted upon in real time across the entire automation network.

Designed to operate within ATOS's Z-ME servo-hydraulic ecosystem, the Z-ME-KZ-PS accepts encoder or LVDT position feedback directly from the hydraulic cylinder or rotary actuator, executes closed-loop PID control at high sampling rates, and simultaneously exposes process data to the plant network through its industrial communication interface. This dual role — precision motion controller and live data source — makes it an indispensable component in any facility pursuing OEE improvement, predictive maintenance, or digital twin integration.

In a fully networked smart factory, the ATOS Z-ME-KZ-PS sits at the intersection of physical motion and digital intelligence. The data flow begins at the sensor layer: a linear position transducer or encoder mounted on the hydraulic cylinder feeds real-time position data into the Z-ME-KZ-PS at millisecond intervals. The controller's onboard DSP closes the position loop locally — eliminating latency that would otherwise compromise accuracy — while simultaneously formatting process variables for upstream transmission.

At the fieldbus layer, the Z-ME-KZ-PS communicates via CANopen, a protocol widely adopted in hydraulic and motion control applications for its deterministic timing and compact message structure. For plants standardized on Ethernet-based protocols, an ATOS CANopen-to-PROFINET gateway or a CANopen-to-EtherCAT bridge module can be inserted between the Z-ME-KZ-PS and the plant backbone, enabling seamless integration without replacing the controller. This gateway approach also allows the Z-ME-KZ-PS to coexist with Siemens S7-1500 PLCs or Allen-Bradley ControlLogix controllers that manage broader machine sequencing, safety interlocks, and recipe management.

From the PLC layer, position setpoints, velocity profiles, and mode commands are dispatched to the Z-ME-KZ-PS in real time. The controller executes these commands against live encoder feedback, and the resulting actual position, following error, valve current, and fault status are returned to the PLC scan cycle. This bidirectional data exchange is then aggregated by a Siemens WinCC SCADA or Ignition SCADA platform, where process engineers monitor hydraulic axis performance across multiple Z-ME-KZ-PS nodes simultaneously on a single dashboard.

For facilities deploying edge computing, an industrial edge gateway — such as a Moxa UC-8100 or Advantech WISE-5000 series — can subscribe to the Z-ME-KZ-PS data stream via OPC-UA or MQTT, pre-process the position and fault data locally, and push condensed analytics to cloud platforms or MES systems. This edge-to-cloud pipeline enables predictive maintenance algorithms to detect valve wear, seal degradation, or hydraulic drift before a production fault occurs.

On the HMI layer, operators interact with the Z-ME-KZ-PS through a Weintek cMT or Siemens TP700 Comfort HMI panel, viewing live position traces, tuning PID parameters, and acknowledging alarms without interrupting the production cycle. The HMI communicates with the PLC over PROFINET, and the PLC relays commands to the Z-ME-KZ-PS over the fieldbus — maintaining a clean, hierarchical data architecture that simplifies troubleshooting and audit trails.

For remote diagnostics, the Z-ME-KZ-PS's fault register and parameter set can be accessed through the ATOS E-SW-CARD programming software connected via USB or RS-232, or remotely through a 4G/LTE industrial router tunneling into the plant network. Maintenance engineers can review historical fault logs, adjust control gains, and verify valve calibration from off-site, reducing unplanned downtime and travel costs. When paired with an ATOS E-ME-AC power amplifier card or an ATOS E-BM-AS proportional valve driver in the same control cabinet, the Z-ME-KZ-PS forms a complete, pre-validated servo-hydraulic drive stack that simplifies commissioning and spare parts management.

Many hydraulic automation sites still operate with analog-only position controllers that produce no digital data, creating blind spots in production monitoring and making root-cause analysis after a fault event entirely dependent on operator memory. The ATOS Z-ME-KZ-PS directly addresses these data gaps by replacing legacy analog cards with a digital controller that logs every position command, actual position, following error, and fault event with a timestamp.

Protocol fragmentation is another common challenge: a plant may run PROFIBUS on older presses, PROFINET on newer machining centers, and CANopen on hydraulic test rigs — with no unified data layer connecting them. The Z-ME-KZ-PS's CANopen interface, combined with a protocol gateway, allows it to participate in any of these network segments without requiring a controller replacement, preserving the existing investment in ATOS valve hardware while modernizing the data infrastructure.

Data islands — where machine data exists only inside a local PLC and never reaches the MES or ERP — are eliminated when the Z-ME-KZ-PS is integrated into a SCADA-connected network. Position cycle times, stroke counts, and fault frequencies become available to production planners, enabling data-driven scheduling and proactive maintenance planning rather than reactive breakdown response.

Remote monitoring is particularly valuable for multi-site manufacturers or OEMs supporting installed machines at customer facilities. With the Z-ME-KZ-PS connected to the plant network and a secure remote access solution in place, service engineers can diagnose a position overshoot, a valve hysteresis issue, or a feedback sensor fault without dispatching a technician — compressing mean time to repair from days to hours.

Alarm traceability is enhanced because the Z-ME-KZ-PS generates structured fault codes rather than generic analog fault signals. Each fault code maps to a specific condition — position error exceeded, enable signal lost, feedback signal out of range — allowing maintenance teams to filter alarm histories in the SCADA system and identify recurring failure patterns that indicate systemic issues rather than random events.

System scalability is preserved because the Z-ME-KZ-PS uses standard fieldbus protocols and a modular parameter structure. Adding a new hydraulic axis to an existing press line requires only a new Z-ME-KZ-PS node on the CANopen segment and a corresponding PLC function block — no rewiring of the control cabinet backbone and no changes to the SCADA server configuration beyond adding a new data tag group.

Q1: What communication protocols does the ATOS Z-ME-KZ-PS support, and can it integrate with PROFINET or EtherCAT networks?The Z-ME-KZ-PS natively supports CANopen for fieldbus communication. Integration with PROFINET, EtherCAT, or PROFIBUS networks is achieved through a compatible protocol gateway module inserted between the controller and the plant Ethernet backbone. This approach allows the Z-ME-KZ-PS to operate within Siemens TIA Portal or Rockwell Studio 5000 environments without firmware modification, and NANKMOS can advise on the appropriate gateway selection for your specific network topology.

Q2: How does the Z-ME-KZ-PS perform in terms of communication latency, and is it suitable for high-speed closed-loop applications?The Z-ME-KZ-PS executes its internal position control loop at a high sampling rate independent of the fieldbus cycle, ensuring that motion accuracy is not compromised by network latency. Fieldbus data — including actual position, following error, and fault status — is updated each CANopen PDO cycle, typically 1–10 ms depending on network configuration. This architecture makes the Z-ME-KZ-PS suitable for precision press control, synchronization applications, and test rig positioning where both motion accuracy and real-time data visibility are required simultaneously.

Q3: Can the Z-ME-KZ-PS be diagnosed and reconfigured remotely without interrupting production?Yes. Parameter read-back and non-critical gain adjustments can be performed through the ATOS E-SW-CARD software interface while the controller is online, provided the connected PLC holds the axis in a safe state during the adjustment window. For fully remote access, a secure VPN or industrial remote access router connected to the plant network allows off-site engineers to access the controller's diagnostic interface, review fault logs, and verify calibration data. NANKMOS provides pre-shipment functional testing documentation for every Z-ME-KZ-PS unit, confirming communication interface integrity before dispatch.

Q4: What warranty and supply assurance does NANKMOS provide for the ATOS Z-ME-KZ-PS?Every ATOS Z-ME-KZ-PS supplied by NANKMOS carries a 12-month warranty covering manufacturing defects and communication interface functionality. Units undergo outgoing quality inspection including power-on verification and parameter integrity checks before shipment. NANKMOS maintains inventory of Z-ME series controllers and associated ATOS servo-hydraulic components to support urgent replacement requirements, minimizing production downtime for customers with critical hydraulic automation lines.
