The Indramat Main Spindle Drive Controller, MPN R911252557 (RAC 4.1-400-460-AP0-W1), is designed for precise control of asynchronous and frameless main spindle motors in numerically controlled machine tools. It provides digital control with high axis stiffness and a broad speed range, supporting accurate C-axis operations at low speeds. Electrical connection is via 3 x AC 400 V, 50 Hz (+/-15%), or 3 x AC 460 V, 60 Hz (+/-10%). The unit includes a high-resolution INDRAMAT encoder, additional encoder input for spindle feedback, X4 9-pole interface terminal, and supports analogue speed command (+/-10V). Cooling is managed by an internal blower and built-in fan, with thermal performance for operation in +5 to +45 °C. Unit is constructed with robust housing and provides for external and internal power dissipation as determined by workload.
