Product Overview & Technical Specs

Designed for high-performance motion control, the drive is characterized by its significant power output and open-frame design:

* Power Output: 7.0 kW (Rated) / 10.0 kVA Mitsubishielectric Shaltzautomation.

* Performance: Features a speed regulation range of 1:5000 and high-precision speed stability (±0.03%) Dosupply.

* Supported Motors: Optimized for high-torque motors such as the HO-SF702 and HA-MH series Dosupply Alfa-Inc.

* Weight: Approximately 29.5 lbs (13.38 kg), indicating its heavy-duty build Radwell.

Market Trends & Lifecycle Status

* Discontinued: The MR-H series is long discontinued by Mitsubishi Electric. Official repair support typically ended around 2008 Sigmasurplus Mitsubishielectric.

* Sourcing Difficulty: New units are virtually non-existent; the market is currently dominated by refurbished, surplus, or used components Williamsautomation Ebay.

* Migration Trend: There is a strong market push toward migrating to modern MR-J4 or MR-J5 series amplifiers, though this often requires motor and cabling upgrades Mitsubishielectric.

Common Operational Issues

As these units age, several critical failure points have emerged in industrial environments:

* AL 52 (Overload): The most common error, often caused by mechanical binding, amplifier power stage failure, or parameter mismatches Industrialmonitordirect Industrialmonitordirect.

* AL 10 (Undervoltage): Frequently caused by aging capacitors within the DC bus circuitry Industrialmonitordirect.

* Maintenance Signal: Many users report needing "hand-starting" for spindles, which indicates a failing current feedback loop inside the MR-H700AN Industrialmonitordirect.

Current market listings show refurbished units starting at approximately $1,053 USD, with stock levels often limited to 1-5 pieces per specialized supplier.
