The Bosch Rexroth Indramat RAC 3.5-150-460-API-W1-220 from the RAC Spindle Drive Controllers series is an advanced AC Main Spindle Drive Controller designed for precision spindle feedback. It operates on a Rated Connection Voltage of 3 x AC 400 V, 50 Hz, +/-15% or 3 x AC 460 V and delivers a Rated Current of 150 A. The drive uses Internal Blower / Built-in fan cooling and accepts control electronics at AC 230 V / 50-60 Hz. Speed control is provided via an Analogue (+/- 10 V) Speed Command and features both Incremental encoder output and an Additional encoder input for spindle feedback compatible with a High-resolution INDRAMAT encoder (~). Connectivity is facilitated through an X4, 9 poles Interface Terminal. This controller, version 5 of series 3, is supplied Without additional bleeder.
