The R911287170 (DKR03.1-W100N-BA05-01-FW) is a DKR series drive controller engineered for precise digital motor control. It operates with a power supply of 3xAC 400-480 V ±10%, delivering a maximum current of 71 A and supporting a rated current of 100 A. Dissipating up to 900 W of heat via a built-in blower and heat sink, it is capable of withstanding up to 150 kW of energy dissipation through its internal brake resistor during mains failure. The unit features an analog command interface, supports both resolver and digital servo feedback, and is configured without a brake chopper (rigid DC bus). It weighs approximately 49 kg and is designed for operation at ambient temperatures from +5°C to +45°C at full capacity, with reduced operation up to +55°C at 80% capacity. Adherence to all provided safety and technical documentation is required during installation and use.
