Frequently Asked Questions

Is this a general-purpose inverter?

No. It is a dedicated spindle servo drive for Okuma CNC machines, not for fans or pumps.

Can I plug and play directly?

No. You need to check version and parameters; some machines require motor matching.

How to fix AL-03 / AL-04 alarms?

AL-03 = overvoltage, AL-04 = undervoltage. Check 3-phase power, power supply unit and DC bus.

What causes AL-06 / AL-07 alarms?

Overcurrent, module failure, motor short circuit or cable grounding issue. Test insulation after power off.

What numbers should I provide for overseas orders?

Provide three codes: A911-3072, POS2A, E0351-263-022.

Can it replace other Okuma drives?

Only replaces the same POS2A model. Not compatible with MIV or BL series.

What to note for export shipping?

It is an industrial spare part. Declare as "OKUMA CNC Spindle Drive".

What are common repair parts?

Power board, drive module, IGBT, current sensor. Not recommended for customer self-repair.

Which machines does it fit?

Mainly for older Okuma lathes and machining centers with OSP700/7000/8000 systems.

Typical overseas repair lead time?

3-7 days for normal repairs; longer if parts are out of stock.
