Mitsubishi MR-E-200A-KH003 – 2kW AC Servo Drive Amplifier | MELSERVO-E Platform
Engineering Background
The Mitsubishi MR-E-200A-KH003 is a compact, high-performance AC servo amplifier from Mitsubishi Electric’s MELSERVO-E series — an economical yet capable servo platform engineered for general-purpose motion control in industrial machinery. Designed for OEM machine builders and system integrators, the MR-E series delivers precise torque, speed, and position control with minimal wiring complexity.
Product Positioning
The MR-E-200A-KH003 targets cost-sensitive automation projects that still demand reliable closed-loop servo performance. With a 2kW (200A) rated output and 200V AC single-phase/three-phase input, this amplifier is ideal for mid-range axis control in packaging lines, conveyor systems, CNC auxiliary axes, and general factory automation. The -KH003 suffix denotes the connector kit variant, ensuring plug-and-play compatibility with Mitsubishi HF-KE and HF-SE series servo motors.

System Architecture & Signal Flow
The MR-E-200A-KH003 operates as a single-axis closed-loop servo amplifier within a standard pulse-train command architecture:
- Command Source → PLC or motion controller outputs pulse train (position) or analog ±10V (speed/torque)
- Servo Amplifier (MR-E-200A-KH003) → Receives command, closes position/speed/torque loop via encoder feedback
- Servo Motor (HF-KE/HF-SE 2kW) → Converts electrical command to mechanical torque and motion
- Encoder Feedback → 2500 p/rev incremental encoder returns position data to amplifier for closed-loop correction
- I/O Interface → Digital I/O for servo-on, alarm reset, limit switches, and ready signals to host PLC
- PC Diagnostics → RS-422 port connects to MR Configurator for parameter tuning and fault analysis
Sourcing & Quality Verification
All units offered by Konmask.com undergo a structured incoming inspection protocol:
- Visual inspection: housing integrity, connector condition, label legibility, and date code verification
- Power-on functional test: DC bus charge, alarm-free initialization, and encoder communication check
- Parameter read-back via MR Configurator to confirm factory defaults or document any prior configuration
- Anti-static packaging with desiccant and shock-absorbing foam for safe international transit
- Each unit ships with a Konmask inspection report and traceable lot documentation
We source exclusively from verified industrial surplus channels, authorized distributors, and decommissioned OEM lines — no gray-market or counterfeit product.

Technical FAQ
Q: Is the MR-E-200A-KH003 compatible with Mitsubishi MELSEC PLCs?
A: Yes. It accepts pulse-train commands from any MELSEC PLC with a positioning module (e.g., QD75, LD75). Analog speed/torque mode is also compatible with analog output modules.
Q: What servo motor does this amplifier pair with?
A: The MR-E-200A is designed for Mitsubishi HF-KE204 / HF-SE204 (2kW, 200V) servo motors. Confirm motor nameplate ratings before substitution.
Q: Can I use an external regenerative resistor?
A: Yes. The MR-E series supports an external regenerative resistor (MR-RB series) when the built-in resistor capacity is insufficient for high-duty-cycle deceleration applications.
Q: What does the -KH003 suffix mean?
A: The -KH003 suffix indicates the unit is supplied with the connector kit pre-included, eliminating the need to order MR-J2CN1 or equivalent connector accessories separately.
Q: Is this unit CE and UL certified?
A: Yes. The MR-E series carries CE marking (EMC Directive, Low Voltage Directive) and UL/cUL listing, making it suitable for deployment in European and North American machinery.
Q: What warranty does Konmask provide?
A: We offer a 90-day functional warranty on all tested units. Extended warranty options are available upon request for volume orders.
