Product Description:
The KDA 3.1-050-3-DY0-U1 spindle drive is manufactured by Bosch Rexroth Indramat. It is designed to meet the demands of precision control in CNC applications. With robust features, this drive delivers reliability and efficiency in various industrial environments.
The KDA 3.1-050-3-DY0-U1 has a rated current of 50 A and runs on a 300 V DC bus voltage. It employs an analog speed command value of +/- 10V to ensure smooth motor operation. The drive also has a digital 16-bit parallel auxiliary interface for flexible connection. The auxiliary encoder input is not provided, making it ideal for simpler setups. The forced cooling system uses an inbuilt heatsink blower that is supplied by a 220V/50-60Hz AC supply. The drive weighs 16.6 kg, with the mechanical mounting kit adding 1.7 kg and the heatsink blower unit weighing 4.2 kg. The device performs efficiently between +5°C and +45°C, with a maximum permitted temperature of +55°C for reduced nominal data. It includes superior motor feedback connections to ensure precise speed and position control. To avoid overheating the unit's cooling system must have an airflow of 32 l/s. The drive's efficient thermal design allows it to run well even under severe loads. It can be stored and transported at temperatures that ranges from -30°C to +85°C.
The KDA 3.1-050-3-DY0-U1 drive can be deployed up to 1000 meters above sea level without compromising performance. The drive protection level is IP10. Proper installation is required, with the device built for vertical mounting to maximize cooling and heat dispersion. It is excellent for precision operations such as spindle positioning and C-axis operation in CNC machines. Additionally, the system uses standardized electrical connections for easy integration with various CNC setups.
