Empirical Engineering Insights

Alternative Models & Compatibility

The FR-A800 series is built with comprehensive backward compatibility for the legacy FR-A700 range. When upgrading an older installation, engineers can directly import A700 parameters using the FR-Configurator 2 software. Note that while terminal functional mappings remain highly aligned, physical chassis dimensions and terminal block layouts may vary slightly, requiring verification of panel mounting space before mechanical installation.

Application Pitfalls & Engineering Notes

In constant torque configurations with high-duty cycles, maintaining proper thermal control within the enclosure is essential. This IP20 drive requires adequate clearance to prevent hot air recirculation. If the ambient temperature inside the panel exceeds 40 degC, nominal output current must be de-rated to prevent premature over-temperature faults. Ensure that an external braking resistor is connected if the system involves frequent, rapid deceleration cycles or vertical load configurations.

Commissioning & Wiring Tips

To eliminate electromagnetic interference (EMI) issues, control and communication cables must be kept separate from high-power output lines (U, V, W). Use shielded twisted-pair cables for the RS-485 control lines and ground the shield only at the drive-end grounding terminal. If using the external 24VDC control supply, ensure the power supply is dedicated to avoid voltage drops caused by other field instruments during peak operations.

Installation Guidelines

CRITICAL WARNING:

Always isolate the mains supply voltage before performing any physical wiring or terminal configuration. After power-off, wait at least 10 minutes to allow the DC link capacitors to fully discharge. Verify that the voltage across the main circuit terminals P/+ and N/- is close to 0 VDC using a certified multimeter before proceeding.

1

Mount the inverter vertically on a flat, non-combustible surface to ensure proper heat dissipation. Maintain a minimum clearance of 50 mm above and below the drive.

2

Connect the main power supply cables to terminals R/L1, S/L2, and T/L3. Ensure proper grounding of the protective earth (PE) terminal.

3

Wire the three-phase motor to terminals U, V, and W. Do not connect power lines directly to output terminals as this will destroy the power module.

4

Complete control and signal wiring using shielded cables. Set appropriate control logic switches before restoring main power.

FAQ

Can I copy parameters from an older FR-A740 inverter directly to this unit?

Yes, you can import and convert FR-A700 series parameters using Mitsubishi FR-Configurator 2 software and transfer them via the built-in USB port.

What is the function of the 24VDC control power input terminal?

This terminal allows you to supply auxiliary control power to keep the communication, parameters, safety monitoring, and diagnostics active when the main 3-phase power is disconnected.

Does this model include an integrated braking transistor?

Yes, this model features a built-in brake chopper. An external braking resistor can be wired directly to terminals P/+ and PR for applications requiring rapid deceleration.

How should I handle thermal de-rating inside closed panels?

For ambient temperatures exceeding 40 degC, you must lower the continuous operating current of the inverter or install filtered exhaust fans to maintain proper internal cabinet temperatures.
