Product Description:
The KDA 2.1-050-3-AQI-W1 Main Spindle Drive supports high efficiency spindle motor control. The unit ensures stable operation under demanding conditions. Its rated performance parameters support consistent torque and speed response. The drive is compatible with analog control systems and meets installation requirements for standard industrial environments.
The Bosch KDA 2.1-050-3-AQI-W1 main spindle drive operates with a ± 10 V analog speed command input. It uses a ± 15 V measuring voltage and consumes 160 mA during operation. The DC bus voltage is rated at 300 V. The rated current of the drive is 50 A that supports high power spindle motors. The forced cooling is achieved via a heatsink mounted blower system. This cooling method maintains temperature control during continuous use. The drive is designed for installation elevations up to 1000 m above sea level without derating. The protection class of the unit is IP10 that is suitable for installation in protected industrial control cabinets. The drive features an auxiliary encoder input for 1 V sinusoidal encoders. This allows closed loop feedback for precise speed and position control. This encoder input supports consistent spindle behavior across variable loads. The drive also includes status monitoring and is compatible with standard control systems in CNC and automation applications. The device construction ensures reliability in consistent duty operations. The analog interface is suited for integration into legacy or hybrid control systems. This allows for flexible applications across various machine types.
The KDA 2.1-050-3-AQI-W1 main spindle drive’s nominal ambient temperature range is from + 5 °C to + 45 °C. This supports operation in standard industrial environments without additional conditioning. The drive weighs 16.6 kg that is manageable for panel installation. Its design allows for vertical mounting in cabinets or enclosures.
