Product Description:
The KDA 3.2-100-3-DQS-U1 Spindle Drive from the manufacturer Bosch Rexroth Indramat is designed for various tasks of industrial automation. It DC bus operates on 300 V DC and supplies a rated current of 100 A for heavy spindle loads. The drive accepts digital 16-bit parallel speed commands for precise spindle regulation and smooth motion control.
The auxiliary encoder input in KDA 3.2-100-3-DQS-U1 spindle drive supports 1 V sinusoidal encoder signals. Its incremental encoder output ensures compatibility with external monitoring systems. The communication with higher-level controllers is established through a serial RS-232C interface. The cooling is achieved by a forced-air heatsink blower that runs on 115 V AC at 50–60 Hz to maintain a continuous thermal balance. The KDA 3.2-100-3-DQS-U1 spindle drive is designed for cabinet mounting with external heatsink dissipation to extend operational life. The system supports very low spindle speeds down to 0.0005 rpm and provides high-resolution C-axis positioning accuracy of one part in 360,000. A microcomputer-based design enables fault diagnostics, drive protection, and parameter storage with keypad access. The spindle drive is engineered to function in environments up to +45 °C and tolerates ambient humidity by Class F insulation per DIN VDE 0530.
The KDA 3.2-100-3-DQS-U1 spindle drive is specified for elevations up to 1000 m without derating and may operate up to 5000 m in certain installations with restrictions. The storage and transportation are supported at temperatures ranging from –30 °C to +85 °C. The unit includes protection against coarse dust and objects above 50 mm, compliant with IP10 standards. It requires at least one minute for DC bus discharge during servicing to prevent electrical hazards. The blower achieves an airflow of 32 L/s at about 30 Pa, ensuring consistent cooling under load.
