Mitsubishi Electric FR-A840-132K-1 FR-A800 Variable Frequency Drive

Description

Engineered for high-capacity heavy industrial applications, the FR-A840-132K-1 variable frequency drive delivers precise motor speed and torque control within the Mitsubishi Electric FR-A800 series portfolio. This high-performance inverter features advanced vector control algorithms and a dedicated FM (frequency monitor) pulse train output terminal to optimize energy efficiency and system feedback across diverse motor topologies, including standard induction and permanent magnet synchronous motors.

Supporting three-phase 380 V to 500 V input distributions, this drive provides a continuous rated output current of 260 A, driving motors up to 132 kW. Standard integration incorporates built-in RS-485, RS-422, and RS-232 serial interfaces to facilitate rapid interfacing with programmable logic controllers (PLCs) and distributed control systems (DCS). Its robust cooling structure and protective design are optimized for reliable continuous operation in harsh manufacturing environments.

Features

• Advanced Real-Time Sensorless Vector Control and PM sensorless vector control for exceptional speed accuracy.
• Built-in safety stop function compliant with EN ISO 13849-1 Category 3/PLd for safe torque off (STO) safety integration.
• Integrated PLC function allowing localized user program execution and custom logic control without an external processor.
• FM type terminal configuration supplying high-speed pulse train output for analog tracking and system monitoring.
• Exceptional overload tolerance designed to withstand harsh transient load spikes during starting and stopping sequences.

Applications

• Heavy-duty municipal and industrial pumping stations.
• High-inertia ventilation fans, industrial blowers, and HVAC air handlers.
• Conveyor systems, automated material handling, and heavy hoisting machinery.
• Industrial mixers, extruders, crushers, and centrifuges.

Technical Specifications

Installation Guidelines

• Mounting: Mount vertically on a flat, non-combustible surface inside an IP2x or IP54 industrial control cabinet to prevent ingress of conductive dust or corrosive gases.
• Clearance Requirements: Maintain a minimum space of 100 mm at the top and bottom of the drive frame to ensure unhindered exhaust airflow from the internal cooling fans.
• Grounding: Connect the ground terminal directly to a dedicated system earth point. Ensure the grounding resistance is 10 ohms or less to limit noise and ensure electrical safety.
• Cable Shielding: Utilize high-frequency braided shielded motor power cables, grounding the shield on both the drive plate and the motor frame to minimize electromagnetic radiation.

Compliance and Certifications

• CE Mark (Low Voltage Directive / EMC Directive)
• UL Listed (US and Canada)
• cUL
• RoHS Compliant
