FANUC power supplies and related parts
The power supply units that feed a FANUC drive system, shelved with the resistors, input units and reactors the seller publishes beside them. One number does double duty in the catalogue, and this page explains why.
Power supply units and related parts
Every amplifier chain starts at a power supply unit: it takes the machine's incoming supply and feeds the servo and spindle amplifiers downstream. The seller publishes the family as power supply units plus three related lines — resistors, input units and reactors — and names one catalogue item for it: the A06B-6200-H026, which the seller also lists as a servo amplifier. That double listing is the seller's own, and both pages carry it, because the number genuinely sits at the junction of the two families.
A failing power supply rarely announces itself as one. It presents as amplifiers alarming together, or a drive chain that drops out under load, so the inquiries that reach this page often start as amplifier inquiries. The desk is used to that and will ask which units share the supply before answering for any one of them.
The power family
The published lines of the family, and the shared numbers.
| Line | Catalogue position | Page |
|---|---|---|
| A06B-6200-H026 | Named power-supply item; also listed as a servo amplifier | Part page |
| Power supply units | The family's main line, stocked by number | Servo amplifiers |
| A06B-6110-H015 | Servo/spindle drive unit on the same chain | Part page |
| Resistors | Published beside the power supplies | Catalogue hub |
| Input units | Published beside the power supplies | Catalogue hub |
| Reactors | Published beside the power supplies | Catalogue hub |
One supply, many alarms
The diagnostic habit worth copying: when several amplifiers on one chain alarm together, suspect the shared supply before condemning any amplifier. When a single amplifier alarms alone, suspect the amplifier. That split decides whether the inquiry belongs on this page or on the servo amplifiers page, and writing the alarm pattern into the message — all axes, one axis, under load, at power-up — gives the desk the pattern to work from.
Bench and shelf for power units
Power supply units are a standard repair family, and a unit that fails under load is exactly what the test bench is for: the fault is reproduced under controlled conditions instead of being guessed from the alarm history. Shelf units carry the seller's condition words; the used parts page sets out what to confirm before a used power unit is ordered for a chain that cannot afford a second stop.
