Product Introduction
The TMEIC ARND-3115A is a sophisticated drive control board engineered by TMEIC (Toshiba Mitsubishi-Electric Industrial Systems) to operate as the core intelligence in medium- and high-performance inverter systems. As a driver module inside TMEIC’s AC inverter families—such as GA700, A7, or legacy G7 series—the ARND-3115A is responsible for executing motor control algorithms, processing feedback signals, and coordinating communication with upper-level automation systems.
Within TMEIC’s modular inverter architecture, ARND-3115A plays a central role: it translates torque/speed commands into PWM switching signals for IGBT modules, monitors system conditions, and handles protection logics. Its design bridges digital signal processing and real-time control, giving the module a high technical positioning: it is not a simple I/O board but a control brain for motor drives. In an automation system, ARND-3115A ensures tight regulation of motor performance, real-time response, and safe, reliable operation of the drive system.
TMEIC has crafted the ARND-3115A to offer compatibility, flexibility, and future-proof integration: it works seamlessly within standardized inverter racks, supports feedback and communication options, and allows parameter cloning and firmware upgrades. As a key component in the TMEIC drive ecosystem, the ARND-3115A delivers advanced motion control functionality with the robustness required in industrial environments.
Core Advantages and Technical Highlights
Functional sophistication: The ARND-3115A is built around a DSP + FPGA hybrid core, enabling it to execute advanced vector control, sensorless control, torque control, and custom motion algorithms with minimal latency. This hybrid architecture ensures deterministic real-time control even under complex load conditions or during rapid setpoint changes.
High reliability: TMEIC designs its boards with industrial-grade components, extended temperature margins, and built-in diagnostics. The ARND-3115A continuously monitors internal voltages, thermal conditions, board integrity, and feedback signal health. In the event of anomalies (such as overcurrent or feedback loss), the board can gracefully protect the power stage and issue early alarms to avoid catastrophic failures.
Modular flexibility: The ARND-3115A supports optional fieldbus interface modules, allowing users to expand connectivity (e.g. PROFIBUS DP, DeviceNet) without redesigning the core. Its firmware is modular and supports parameter cloning, so swapping boards in the field is faster. The board’s interface to I/O, feedback, and communication is designed to be modular and decoupled, facilitating upgrades over time.
Compatibility and ecosystem: ARND-3115A integrates natively in TMEIC inverter systems (GA700, A7, etc.), enabling smooth pairing with power modules, I/O boards, feedback units, and operator panels. This compatibility ensures that ARND-3115A can be used across multiple inverter models, reducing spare part variety and simplifying lifecycle support.
Ease of use: TMEIC typically pairs the ARND-3115A with configuration software (such as TMdrive-Navigator) that provides GUI parameter editing, monitoring, diagnostics, and trend logging. Engineers can back up configurations, clone settings to multiple boards, and diagnose faults remotely. The board’s LED indicators and diagnostic outputs also assist in efficient commissioning and troubleshooting.
Enhanced protection: The ARND-3115A implements protection functions such as overcurrent, overvoltage, undervoltage, thermal shutdown, stall detection, feedback loss, and input supply monitoring. These protective features guard both the module and connected power stages, enhancing system robustness in demanding industrial settings.
Typical Application Scenarios
Given its high performance, modularity, and reliability, ARND-3115A is well-suited to demanding industrial drive applications across many sectors. In the metals or steel industry, it may be used to control rolling mill motors, tension control drives, coil handling systems, or auxiliary equipment—with precise torque and speed regulation necessary to maintain product quality. In the mining and mineral processing sectors, ARND-3115A can manage crusher motors, conveyor drives, or grinding mills, where variable load conditions and long duty cycles demand resilient control.
In the petrochemical, chemical, or pump industry, ARND-3115A supports centrifugal pump or compressor drives. Its vector or sensorless control enables efficient flow regulation, and its diagnostic capabilities help prevent unexpected shutdowns. Because it can integrate with plant-level SCADA or DCS systems through Modbus or optional bus interfaces, ARND-3115A is suitable for modernization or retrofit projects where interoperability is critical.
In the power and utility sectors, ARND-3115A might be employed in fan, blower, or boiler feedwater pump drives—applications where energy efficiency, soft-start, and smooth control are vital. The board’s fault monitoring, redundancy readiness, and predictable behavior under fault conditions give operators confidence in continuous operation.
Moreover, ARND-3115A is useful in any scenario requiring precise motion control, such as automation lines, material handling conveyors, crane drive control, or synchronizing multiple motors. By combining performance, reliability, and modularity, ARND-3115A proves itself a versatile control module in complex industrial drive systems.

Installation, Commissioning and Maintenance Instructions
Installation preparation: Before installing ARND-3115A, ensure the inverter cabinet or rack is fully de-energized and locked out. Confirm ambient temperature, humidity, and dust levels meet specifications, and that vibration is within tolerance. Use ESD-safe practices—wear an anti-static wrist strap, work on an ESD bench, and avoid direct contact with connector pins. Inspect the board visually for damage or contamination prior to insertion.
Mount the ARND-3115A onto the designated slot or backplane within the inverter, carefully aligning connectors to avoid bending pins. If mechanical fasteners or retaining latches are used, ensure proper torque without over-stressing the board. Connect signal, feedback, and communication wiring properly, using shielded cables and proper routing to minimize noise coupling.
Commissioning: Power up the main drive and monitor board LEDs for power, status, and fault indications. Using TMdrive-Navigator or the provided configuration tool, upload the hardware configuration, set motor and control parameters, and download firmware if required. Perform initial tests in “test mode” or with no-load motor to validate basic functionality, feedback response, fault handling, and communication with higher-level controllers. Conduct step response, ramp up/down tests, and ensure protection trip thresholds behave as expected.
Maintenance suggestions: Periodically review fault logs and operational statistics from ARND-3115A to detect early warning indicators (e.g. trending of temperature, repeated minor faults or warning events). Clean the board and ambient enclosure by using dry, low-pressure air—avoid direct contact with components. Check connector integrity, torque, and wiring insulation periodically. When replacing a failed ARND-3115A, load the backed-up parameter set into the new board before installation to reduce downtime. Store spare boards in anti-static bags, in temperature-controlled and low-humidity conditions. If any firmware patches or updates are released, validate in a test bench before updating production units.
