FR-E840-0170-4-60 | Mitsubishi Electric | Variateur FR-E800

Description

Designed for robust speed control in industrial three-phase systems, the FR-E840-0170-4-60 variable frequency drive operates within the high-performance Mitsubishi Electric FR-E800 family. This compact, versatile inverter supports 400V class three-phase electrical supplies, delivering efficient control of induction and permanent magnet motors. Featuring an integrated conformal circuit board coating (denoted by the -60 suffix), the unit is optimized for protection against harsh atmospheric conditions such as humidity, dust, and corrosive vapors, ensuring long-term operational reliability in demanding production environments.

The unit features analog voltage monitoring via the dedicated AM terminal and is configured with source logic for both standard input signals and its integrated safety stop loop. It is engineered to seamlessly integrate into standardized control architectures, offering a balanced power-to-size ratio suited for decentralized control cabinets and modular machinery designs.

Features

• Conformal Circuit Board Coating: Factory-applied protective coating (-60 specification) guards sensitive internal electronics against moisture and airborne pollutants.
• Standard Source Logic: Features source logic configuration for both the main control input signals and the dedicated safety stop safety loop.
• Analog Voltage Monitoring: Includes terminal AM for real-time monitoring of output voltage parameters.
• Efficient Thermal Design: Compact frame size optimized for side-by-side mounting configuration inside control panels.

Applications

• Conveyor systems and material handling machinery.
• Industrial fan, blower, and ventilation controls.

Installation Guidelines

• Mounting Orientation: Mount the inverter vertically on a flat, heat-resistant surface to ensure optimal natural convection.
• Clearance Requirements: Maintain a minimum clearance of 50 mm above and below the unit, and 5 mm on either side for proper airflow.
• Wiring Best Practices: Use shielded power and control cables to minimize electromagnetic interference (EMI). Keep control signal wiring separated from high-voltage motor lines.
• Grounding: Securely ground the unit using the ground terminal to prevent electrical shock and reduce industrial noise coupling.

Compliance and Certifications
