Litco inventory record match
RAC2 overview
RAC2 belongs to the RAC Main Spindle Drives platform. Spindle-drive family represented across multiple Litco inventory records; verify current stock.
Main-spindle drive controllers identified by complete type code, current class, command input, firmware and motor pairing.
The base model identifies a useful frame or product group, but it is not enough by itself to select a replacement. Electrical design, feedback, mechanical interface, brake, cooling, firmware and installed options can all change inside one model group.
Send the full nameplate plus photos of the unit and connections. Litco can route the request toward a verified inventory check, repair evaluation, exchange or a technical follow-up.

Inventory records are a starting point, not a live-stock promise. Litco verifies the complete code, physical unit, condition and current stock before quoting.
RAC2 main-spindle controller notes
RAC2 controllers were planned for regulated main-spindle systems with 2AD asynchronous motors and 1MB frameless spindle motors.
| Current-rating fields | 150, 200 or 250 A |
|---|
| Supply fields | 380 or 460 V |
|---|
| Command interfaces | Analog, digital or SERCOS depending on configuration |
|---|
| Additional selection | Second encoder, additional interface, auxiliary bleeder and cooling |
|---|
| Programming | The AS programming module and motor/controller combination ID are part of the system match |
|---|
Compatibility checkpoint: No RAC2 should be represented as interchangeable by frame alone. Controller suffix, programming module and motor combination must be verified.

Compare RAC2 with the surrounding product family and installed system before planning a substitute.
Repair, testing and exchange
Use one intake for a repair evaluation, exchange request or replacement search. Describe the failure, capture any display or drive fault, identify the machine and axis, and preserve parameters or application data before removing control hardware.
Other RAC model groups
Use the exact model characters on the label. Neighboring groups can use different frames, power classes, interfaces or mechanical packages.
