Series overview

What RAC3 identifies

The RAC3 series combines high-power electronics with machine-specific command and feedback arrangements. A technician should compare the full controller code, connected spindle motor and cabinet mains components before approving a substitute.

Ratings, connections, feedback, braking and mechanical options vary by complete type code. Send Litco Automation a clear nameplate photo so the exact configuration and compatible replacement can be confirmed.

Series questions

RAC3 questions

Before Litco pulls a unit

Is RAC3 enough information to order a replacement?+

No. RAC3 identifies the series group, but the complete type code still carries the current, command, communication, feedback, firmware and installed-module options that determine compatibility.

Which RAC3 fields should I compare first?+

Start with complete rac type and current class; mains-voltage and cabinet-power arrangement; spindle-motor and feedback type. Then preserve the remaining suffix, material number, revision and every installed option or firmware label.

Where is RAC3 equipment commonly used?+

RAC3 is documented for cnc main spindles, machining centers, high-power production machinery, legacy spindle-drive cabinets. The installed machine, axis and connected equipment still control the final replacement decision.

Can Litco evaluate a failed RAC3 unit?+

Yes. Litco can discuss replacement, repair and exchange paths after reviewing the complete code, application and failure information.
