System Architecture & Signal Flow
The MR-J3-200AN operates within Mitsubishi’s Motion Control ecosystem as follows:
- Controller Layer: Mitsubishi Q-series / L-series PLC or Motion Controller (e.g., Q172DCPU, LD77MS) issues position commands via SSCNET III fiber link
- Amplifier Layer: MR-J3-200AN receives commands, executes real-time current/velocity/position loops at 62.5 µs cycle time
- Motor Layer: Paired with HF-SP202 / HF-KP series servo motors (2kW, 200V class); encoder feedback closes the position loop
- Safety Layer: Hardware base-block (EM1/EM2), dynamic brake, and over-current/over-voltage protection circuits
- Diagnostics Layer: MR Configurator2 software provides real-time waveform monitoring, alarm history, and parameter backup

Technical FAQ
Q: Is the MR-J3-200AN compatible with MR-J3-200A motors?
A: Yes. The MR-J3-200AN is the analog/pulse-train variant of the MR-J3-200A. It is fully compatible with HF-SP202, HF-KP23, and equivalent 2kW J3-series servo motors.
Q: Can this drive operate on single-phase 200V input?
A: Yes, single-phase 200–230V AC input is supported for the 2kW class, though 3-phase input is recommended for continuous high-load operation to avoid derating.
Q: What is the difference between MR-J3-200AN and MR-J3-200B?
A: The MR-J3-200AN uses analog/pulse command interface; the MR-J3-200B uses SSCNET III fiber-optic bus exclusively. Selection depends on your controller’s communication capability.
Q: Does Konmask provide MR Configurator2 setup assistance?
A: Yes. Our technical team can provide parameter templates, wiring diagrams, and remote commissioning guidance for standard applications.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. Out-of-stock lead time is typically 2–4 weeks depending on sourcing channel.
