The R911200263 (RS51.1-4G-003-L-V1-FW) is a drive control unit engineered for high-speed grinding spindle applications. It supports 3-phase AC input at 380–480 V, with a rated power of 3 kVA and a nominal current of 5 A. The design integrates a brake chopper, resistor, line reactor, and a radio interference suppression filter. Operating with forced air cooling, it offers a 150% overload capacity for one minute and features a four-line display. The unit, J size code, weighs 20 kg. Contact with resistors, heatsinks, or housing during operation is unsafe due to high surface temperatures. Power connections should include an emergency stop isolation, and the device requires dedicated firmware. Installation and storage must be in clean, dry environments.
