The drive controller R911298312 (DKR03.1-W100N-BT49-01-FW) is designed for integration into industrial automation systems, utilizing a 3-phase AC supply at 400-480 V and 50-60 Hz. It operates with a control voltage of 230 V AC and provides a nominal current of 100 A. The device features five plug-in slots, with firmware required for the fifth slot to be ordered separately. The protection rating is IP20, suitable for environments with protection against solid objects greater than 12.5 mm but not against water ingress. The operating temperature range is +5 to +45°C, with derating to 80% at +55°C, and installation is possible up to 1000 m altitude. The controller supports both digital servo and resolver feedback, employs a SERCOS interface for command input, and uses air cooling with a built-in blower. Two output configurations are available: at 4 kHz, the unit delivers 26 kW at 800 Hz and 71 A; at 8 kHz, it provides 22 kW at 1600 Hz and 60 A. The DC bus is rigid and the unit does not feature a brake chopper (bleeder configuration: no bleeder).
