Mitsubishi HA200NC-S — 2.0 kW Medium-Inertia AC Servo Motor for Industrial Motion Control

MITSUBISHI ELECTRIC · AC SERVO MOTOR · HA-NC SERIES

Product Overview

The Mitsubishi HA200NC-S is a 2.0 kW brushless AC servo motor built for continuous-duty industrial operation. Part of the medium-inertia HA-NC series, it is engineered to deliver consistent torque output and precise positional control across the demanding duty cycles common in manufacturing automation.

The motor integrates directly into Mitsubishi Electric's MELSERVO platform, pairing natively with MR-J series servo amplifiers. That ecosystem compatibility isn't a minor convenience — it eliminates the manual parameter calibration typically required when mixing components from different vendors, which translates to faster commissioning and fewer startup headaches on the plant floor.

The "-S" suffix in the model designation indicates a keyed shaft output. The keyway allows secure, slip-free mechanical coupling to gearboxes, timing pulleys, and couplings without relying solely on friction or adhesive methods.

Key Specifications

What the HA200NC-S Does Well

Sustained output under load. The motor's thermal design supports operation at rated torque for extended periods without triggering protective derating — a distinction that matters on production lines running multiple shifts.

IP65 protection in wet environments. Fully sealed against dust and resistant to low-pressure water jets, the HA200NC-S holds up in CNC environments where coolant mist and fine swarf are a constant. The sealing is not a marketing claim; it reflects the IEC 60529 standard the unit is rated to.

Stable control across the speed range. The integrated high-resolution encoder provides fine feedback to the servo amplifier at both high and low speeds, which keeps the control loop stable even when axis velocity drops near zero — a common weak point in lower-grade servo motors.

Medium-inertia rotor geometry. The rotor is designed to balance acceleration responsiveness against smooth velocity profiles during direction reversals. For applications with variable or asymmetric load inertia, this characteristic reduces the risk of oscillation without requiring aggressive gain adjustments in the amplifier.

Drop-in replacement availability. Because the HA-NC series follows consistent mechanical and electrical conventions, the HA200NC-S is a practical replacement option in machines originally specified around earlier Mitsubishi servo units of the same frame class.

Typical Applications

The 2.0 kW output and medium-inertia classification place the HA200NC-S in a range that suits axis drives requiring more force than a light-duty servo can provide, but without the inertia penalty of a heavy-frame unit. Engineers routinely specify it for:

• CNC milling and turning center axis drives
• Industrial robot joint actuators
• Automated assembly and pick-and-place systems
• Conveyor indexing and positioning
• Injection molding auxiliary axes
• Printing and packaging machinery
• Laser cutting gantry control

Drive Compatibility

The HA200NC-S is built to work within Mitsubishi Electric's MELSERVO ecosystem. It connects directly to MR-J series servo amplifiers — including the MR-J2S-200A, MR-J3-200A, and MR-J4-200A — and is recognized by the amplifier's auto-tuning routines without custom parameter mapping. This makes it a straightforward integration in both new machine builds and field replacements where the existing amplifier is being retained.

Always verify the specific amplifier-motor pairing against Mitsubishi Electric's official compatibility documentation before commissioning.

FAQ

Q1. What is the rated output of the Mitsubishi HA200NC-S? The HA200NC-S is rated at 2.0 kW. It is a continuous-duty motor designed for sustained industrial operation within the MELSERVO drive system.

Q2. Which servo amplifiers are compatible with this motor? It is designed for use with Mitsubishi MR-J series amplifiers — most commonly the MR-J2S-200A, MR-J3-200A, and MR-J4-200A. Confirm the specific pairing against Mitsubishi's compatibility matrix for your application.

Q3. What does the "-S" in the part number indicate? The "-S" suffix designates a keyed shaft. The shaft includes a keyway slot for positive mechanical coupling to gearboxes, pulleys, and other driven components.

Q4. What is the IP rating, and what environments does it cover? The motor is rated IP65 — fully protected against dust and resistant to direct water jets. It is suitable for CNC machining environments where coolant spray and airborne particulates are present.

Q5. Can the HA200NC-S replace an existing servo motor in an older machine? Yes, it is commonly used as a replacement unit in machines built around the HA-NC series. Before installation, verify the shaft dimensions, encoder connector type, and amplifier model to confirm full mechanical and electrical compatibility.
