The R911256085 (RAC 3.5-100-460-API-W1-220) is an AC main spindle drive controller engineered for three-phase AC power supplies at 380V-460V (50-60Hz), with a rated current of 100A and a control electronics supply of 220V. Speed command is achieved via an analogue interface (+/-10V), and additional encoder input is available for either spindle or second motor feedback, supporting high-resolution INDRAMAT encoders. The drive contains an internal blower for cooling, with optional provisions for hose-based external cooling. Connection interfaces include a 9-pole X4 terminal and an incremental encoder output. The device operates optimally from 5 to 45°C, at altitudes below 1000m, and in environments under 70% relative humidity. Protection conforming to IP10 is provided, with IP54 inside a cabinet and IP24 for the cooling fan.
