Yaskawa CACR-SR03BB1HS Servopack – Compact 200 V-class AC servo drive for precise, analog-controlled motion

The Yaskawa CACR-SR03BB1HS belongs to the proven CACR-SR Servopack family, widely used on packaging lines, printing machines, and legacy CNC axes where a stable analog command and dependable speed/torque response are required. From my experience, this unit is a go-to when you need a drop-in replacement that preserves existing ±10 V command schemes and standard I/O without rewriting your PLC or motion program. It seems to be most comfortable driving small-to-medium 200 V-class servomotors, delivering quick response and clean velocity control in many cases.

One thing I appreciate is how predictable the tuning feels on these SR-series amplifiers—gain and compensation pots make on-site touch-ups straightforward, and the alarm signaling is simple to integrate with older control cabinets. If you’re stabilizing an axis on a retrofit or keeping a mature machine productive, this model typically saves hours of redesign.

Application Fields

You might notice this model showing up in retrofit and life-extension projects where the control strategy is already proven. Typical applications include:

• Packaging machinery: film feeders, sealing jaws, and labeling axes using analog velocity loops
• Printing and converting: web tension, unwind/rewind, and register control
• CNC and machine tools: auxiliary axes, spindles with analog speed control
• Electronics assembly: pick-and-place feeders and conveyors
• Textile and wire processing: constant torque winders and pay-off systems

“We swapped in a CACR-SR03BB1HS on a mid-90s wrapper, kept the ±10 V loop intact, and the line was back up same day.” — Maintenance Supervisor, Food Packaging

Advantages & Value

• Reliability – CACR-SR units are known for robust protection and long service life in 24/7 duty.
• Compatibility – Keeps legacy analog control schemes; no need for new fieldbus cards or PLC code changes.
• Cost saving – In many cases, a like-for-like replacement avoids a full drive/motor/platform migration.
• Technical support – Parameter cross-reference and wiring guidance help reduce commissioning time.

Installation & Maintenance

• Cabinet standards – Mount vertically on a rigid backplate. Allow ventilation space above and below; avoid heat sources directly beneath.
• Power & grounding – Use a dedicated 200–230 VAC supply with proper grounding. A line reactor and EMI filter are advisable in noise-heavy plants.
• Wiring – Shielded command/feedback cables, separated from motor power. Keep encoder and analog lines away from contactor and VFD cables.
• Tuning – Start with conservative gains; adjust velocity/torque loops via front-panel pots. Many technicians prefer a light load check before full speed.
• Routine maintenance – Quarterly dust cleaning, terminal re-torque checks, and fan/air path inspection. Electrolytic capacitors on older units benefit from periodic health checks.

Quality & Certifications

• Manufacturer certifications typically include CE and UL/cUL for relevant series generations
• RoHS compliance may vary by production year for CACR-SR models
• Warranty: 12 months (365 days)

Compatible Accessories & Supporting Components

• Yaskawa 200 V-class servomotors from the same era (e.g., S-series/SGM-series with pulse coder feedback)
• Motor power and encoder/pulse-coder cables matched to motor model and cable length
• External regenerative resistor (when required by duty cycle), line reactor, and EMI/RFI filters
• Panel cooling fans and filtered vents to maintain stable internal temperatures

If you’re replacing an existing CACR-SR unit, sharing the motor model and any available parameter sheet typically speeds up a smooth, first-try startup.
