Designed for precision speed and torque control in heavy industrial environments, the Mitsubishi Electric FR-A840-00170-2-60 is a high-performance three-phase variable frequency drive belonging to the premium FR-A800 series. This standard model operates on a 400V class input and is engineered with an SLD (Super Light Duty) rated current rating of 17 A. To ensure long-term reliability in harsh operational environments, the unit features a specialized protective conformal circuit board coating (Class 3C2) without plated conductors, providing superior resistance to corrosive gases and moisture. Its robust cooling system relies on forced air circulation to maintain optimal thermal conditions inside enclosed electrical cabinets.

This model serves as a modern replacement for the legacy FR-A740 series. While physical footprint changes are minor, the control terminal layout is optimized. Parameter configurations from older FR-A740 units can be seamlessly imported using the FR Configurator2 software utility. Always check terminal strip physical spacing if replacing an older generation drive inside a tight control panel.
The -60 suffix specifies a 3C2 conformal board coating. This is highly recommended for wastewater, pulp and paper, or chemical processing sites. However, because this model is designed without plated conductors, it should not be exposed to severe atmospheric concentrations of chlorine or sulfur salts that exceed Class 3C2 specs. If operating under high ambient temperatures, thermal derating curves must be applied to prevent overtemperature faults (E.THT).
Always ensure that control signals are isolated from high-power cable runs. Keep control and power cables in separate wire trays or use shielded cables grounded at the drive end only. False ground fault trips (E.GF) can occur if leakage currents from long motor cable runs exceed the threshold; installing an output dV/dt filter or a common-mode choke will mitigate this issue during commissioning.
