Product description

What to know about RAC4.3-300-460-A-0D-W1

The RAC4.3-300-460-A-0D-W1 is an Indramat RAC drive controller built for AC main-spindle applications. RAC controllers combine high-power motor regulation with application-specific feedback and command electronics in legacy machine-tool systems.

The type code identifies RAC line 4, design 3, a 300 A class and 460 V supply designation. The A-0D-W1 configuration must be matched to the original machine; W1 denotes a blower-cooled arrangement.

Because the power and configuration are substantial, Litco confirms the complete plate, cabinet supply and motor before quoting. Repair may be the best path when machine parameters or interfaces are difficult to recreate.
