Product Description:
The KDA 2.1-150-3-L0S-W1 is a spindle drive unit. It is developed by Indramat. It is designed for CNC spindle positioning and C-axis control.
The Bosch Indramat KDA 2.1-150-3-L0S-W1 is created for high-precision machine tools. The rated current for this drive is 150 A. It provides a steady current of 90 A for long-term activities. The unit operates on a 300 V DC bus voltage. This model belongs to the advanced KDA Spindle Drives series. The unit operates reliably at ambient temperatures ranging from +5°C to +45°C. It can operate at reduced performance up to +55°C. The storage temperature varies from -30°C to +85°C. Its cooling is accomplished through forced air using a heatsink blower. The blower requires a 220 V AC power supply at 50-60 Hz. The mounting orientation is vertical, with grounding bolts at the top. The total unit weight is 17.4 kilograms. The M1-KD mechanical mounting kit adds 1.7 kg and the LE4-220V blower unit adds 4.2 kg. Total accessory weight is 5.9 kg. Speed command input is supported via the SERCOS interface over a fiber optic line. It includes a serial RS232C auxiliary port. The drive communicates to NC control via an X2 (37-pin) interface. Feedback signals are supported by the X3 (15-pin) connector. Blower connections are made using X14a and X14b terminals. The maximum installation height is 1000 meters above sea level. The relative humidity must not exceed 70%, according to DIN 40 040 norms.
The KDA 2.1-150-3-L0S-W1 meets industrial EMC standards. The DIN 40 050 rules specify an IP10 protection category. It is compatible with both 2AD asynchronous and 1MB frameless spindle motors. With feedback, position control precision can reach 1/2,000,000 revolutions. The control voltage is given by a bus connection from the supply module. It is ideal for CNC spindle systems. This spindle drive fits vertical enclosures using M1-KD and LE4-220V. It supports precise operations with fiber optic SERCOS connectivity.
