Commander S100 repair and refurbishment.

Component-level repair for the Commander S100. Bench diagnostics, engineer-led, outcomes tested before return.

Overview

Commander S100 repair and refurbishment

The Commander S100 is a compact, entry-level drive with a clean design suited to simple speed control applications. Despite its small format, it contains the same failure-prone components as larger drives — particularly in the power stage and DC bus.

Expertise

Common Commander S100 faults we fix

  • Power stage IGBT failure presenting as an immediate overcurrent trip on startup or during acceleration

  • DC bus capacitor failure causing undervoltage trips or reduced braking performance on frequent start-stop cycles

  • Operator keypad failure preventing local parameter adjustment — common in dusty or high-humidity installations

  • Internal fuse failure following transient overvoltage events on the supply

FAQ

Commander S100 repair FAQs

Is it worth repairing a Commander S100, or should I replace it?

For production-critical applications, repair is usually the faster and more cost-effective option — especially where a replacement would require re-wiring or re-parameterisation. We offer a clear quote before any work begins.

Can you repair a Commander S100 that has suffered a supply voltage surge?

Yes. Surge damage typically affects the input rectifier, DC bus capacitors, or internal fuse. We carry out a full diagnostic to identify all affected components before quoting.

My Commander S100 shows no display on power-up — is the drive repairable?

A blank display can indicate a blown internal fuse, power supply rail fault, or control card issue. We carry out bench diagnostics to identify the root cause before advising on repair.
