ORMEC SAC-SW220EB – ServoWire AC servo axis module for 200–240 VAC motion systems

The ORMEC SAC-SW220EB is a ServoWire-based AC servo axis module designed for tightly coordinated motion on packaging lines, pick-and-place stations, assembly cells, and web handling equipment. It sits on ORMEC’s deterministic ServoWire (IEEE‑1394) network and typically pairs with an ORMEC SMLC or ORION controller for multi-axis synchronization, electronic gearing/camming, and fast I/O response. One thing I appreciate is how clean the wiring becomes—power and motor leads are local, while motion commands and timing travel over the high-speed ServoWire link.

From my experience, the SAC series is a good fit when you want cabinet-mounted servo amplifiers with centralized control logic. You might notice that commissioning feels familiar if you’ve worked with ORMEC before—typical tools, clear fault diagnostics, and deterministic axis updates. For brownfield upgrades, it seems to be especially helpful where precise registration and coordinated moves are needed without overhauling the entire cabinet.

Key Features

• ServoWire (IEEE‑1394) motion network – Deterministic, high-speed axis updates for coordinated motion under SMLC/ORION control.
• 200–240 VAC class – Suited to common plant mains; ideal for small-to-mid power brushless AC servo motors.
• Compact cabinet mounting – Streamlined panel wiring; power local to the axis, commands over a single network cable.
• Position/velocity/torque modes – Flexible control modes to match application needs, from indexing to electronic camming.
• Integrated protection – Over‑voltage, over‑current, and over‑temperature safeguards typical for this series.
• Practical diagnostics – Clear status and fault reporting shorten troubleshooting time during commissioning.

Related or Supporting Products

• ORMEC SMLC – SmartMotion Logic Controller that commands ServoWire axes; ideal when you need coordinated multi-axis motion and IEC-style logic.
• ORMEC ORION – Motion controller alternative for legacy or mixed-architecture systems.
• ORMEC SAC-SW075EB / SAC-SW110EB – Similar ServoWire axis modules with lower power ratings; suitable when motor current is modest and cabinet space is tight.
• ServoWire (IEEE‑1394) Cables – High-quality FireWire cabling for deterministic networking; lengths selected per cabinet layout.
• Braking Resistor & Line Filter – Common accessories for dynamic braking and mains filtering in regenerative or high-inertia applications.

A packaging OEM told us they cut tuning time by roughly 30% moving to ServoWire axes with an SMLC because the network timing was predictable and the diagnostic messages were straightforward. That kind of time-saving typically shows up during factory acceptance tests.

Installation & Maintenance

• Cabinet standards – Mount in a clean, dry enclosure; follow UL 508A/NFPA 79 practices where applicable. Keep conductive dust and oil mist away.
• Ventilation – Install vertically with adequate clearance (top/bottom) for convection or forced-air cooling. Avoid stacking heat sources tightly.
• Wiring – Use proper grounding, shielded motor/feedback cables, and separate power from signal routing. Verify earth bonding and EMC filtering.
• Network – Daisy-chain ServoWire cabling with correct terminators and bend radius. Keep cable runs secure to prevent intermittent faults.
• Safety – Integrate E‑Stop and gate switches at the system level. If using a braking resistor, size it for duty cycle and ambient conditions.
• Routine maintenance – Periodically check connector torque, fans/airflow, and cabinet filters; back up drive parameters and controller project files. Firmware updates may be applicable depending on the controller toolchain.

Quality & Certifications

• CE marking (EMC and Low Voltage), typical for ORMEC ServoWire drives
• UL/cUL recognition for panel installation (model and region dependent)
• RoHS compliance on many builds; confirm per lot if your project requires it
• Manufacturer’s warranty: 12 months (our supply warranty is 365 days as stated above)
