06 / Overview

About Mitsubishi Electric VFD Repair

Mitsubishi FR faults read plainly: E.OC (overcurrent) at the IGBT/motor, E.OV (overvoltage) at braking/supply, E.THM/E.THT (overload) at the motor or duty, and E.FIN (heatsink overheat) at cooling — a frequent one in Hyderabad's dust. We read the fault history in FR Configurator2, test the power stage and DC bus, and check the fan and heatsink before quoting.

FR-A700 and FR-S500 are end-of-life; we repair them at component level and migrate parameters to FR-A800/FR-E800 when the power board is no longer available.

Frequently asked questions

Our FR-A800 trips E.OV1 during deceleration. How do you fix that?+
E.OV1 is DC-bus overvoltage during acceleration/deceleration — the load regenerates energy the drive can't dissipate. The fix is usually a working brake resistor and chopper, or a longer deceleration ramp; occasionally it's supply overvoltage. We check the brake circuit and ramp settings first, which resolves most E.OV faults without a drive swap.
Do you repair Mitsubishi Electric vfd repair or only replace units?+
We repair at component level wherever it is economical — FR-D700 / FR-D720, FR-E700 / FR-E800 and FR-A700 / FR-A800 and related models. Replacement is recommended only when the unit is genuinely beyond economic repair or spares are unobtainable, and we will tell you which rather than defaulting to a costly swap.
Which Mitsubishi Electric models do you cover for VFD repair?+
We service FR-D700 / FR-D720, FR-E700 / FR-E800, FR-A700 / FR-A800, FR-F800 and FR-S500 (legacy), including current and end-of-life generations. Tell us the exact model when you raise a request and we match a technician experienced on that Mitsubishi Electric platform.
Will my Mitsubishi Electric settings survive the repair?+
Yes. We back up parameters and programs with GX Works2 / GX Works3 before any hardware work and restore or verify them after repair, so your commissioning, Mitsubishi Electric application settings and referencing are preserved.
How quickly can you provide Mitsubishi Electric VFD repair?+
We're a verified-technician network serving factories across India from our Hyderabad base. For registered factories we dispatch a technician in under 4 hours across Hyderabad's industrial clusters, and within hours through local technicians in other regions — including emergency Mitsubishi Electric breakdowns, 24/7. Where workshop repair is needed we collect, repair and reinstall with full load testing.
