01 / The work

What vfd repair actually involves

A variable frequency drive that trips on overcurrent, throws a DC bus fault or refuses to start usually fails for one of a small number of reasons — a shorted IGBT module, a degraded DC bus capacitor bank, a failed cooling fan, or a motor-side insulation fault that the drive is correctly reporting as its own problem.

Our technicians carry drive test equipment to site, so the first job is always deciding whether the fault is in the drive, in the motor, or in the cable between them. That distinction changes the repair entirely and is the step most often skipped.

02 / Scope

VFD Repair on site

Board-Level Repair

IGBT and rectifier module replacement, gate driver repair, DC bus capacitor reforming and replacement.

Motor-Side Isolation

Insulation resistance and winding tests to confirm whether the drive or the motor is actually at fault.

Parameter Recovery

Drive parameters read, documented and restored after repair or replacement, so the machine runs as it did before.

03 / Common faults

Questions we get asked on site

The faults that bring us out most often, and what gets checked first.

Why does the VFD trip on overcurrent at startup?+
Most often a shorted IGBT, a motor winding or cable insulation failure, or an acceleration ramp set too aggressively for the load's inertia. Mechanical binding on the driven equipment produces the same symptom, so the load is checked before any parameter is changed.
What causes an overvoltage fault during deceleration?+
A decelerating load feeds regenerated energy back into the DC bus. If the deceleration ramp is too short, or the braking resistor or braking chopper has failed, the bus voltage rises past the trip threshold. The braking circuit is checked before the ramp is extended.
Is a failed drive worth repairing or should it be replaced?+
It depends on power-stage damage, control-board condition, spare availability and whether the model is still supported. A drive with a failed fan or capacitor bank is almost always worth repairing; one with a destroyed power stage on an obsolete platform often is not.
