Product Description:
Bosch Rexroth is a global manufacturer of drive and control technologies. The company develops components and systems for industrial automation, energy efficiency and motion control. Its expertise covers electric drives, hydraulics, pneumatics and linear motion.
The KDA 2.1-050-3-LPD-U1 Main Spindle Drive is engineered for precision control and stable performance. It delivers a rated continuous output current of 50 A and operates on a DC bus voltage of 300 V. The unit uses forced cooling through a heatsink blower for efficient thermal management. The blower supply requires 115 VAC input. The speed command interface is handled via SERCOS communication while an auxiliary encoder input is available for spindle or second motor feedback. The SERCOS command compatibility allows seamless integration with digital control systems. The auxiliary digital interface supports 16 bit parallel position commands. The parallel auxiliary interface provides high precision position data handling. The integrated microcomputer in this model provides drive control and monitoring functions that ensures stable operation. The diagnostic features include LED indicators or display sections for fault, status and operating condition feedback. The LED diagnostic indicators improve serviceability by providing clear status feedback.
The protection systems of this KDA 2.1-050-3-LPD-U1 main spindle drive include over temperature and over voltage safeguards with built in monitoring against overcurrent, bridge fuse faults or ground fault conditions. The over temperature protection prevents thermal overload in the electronics while voltage spikes are countered by over voltage protection. The unit detects missing or invalid encoder or resolver feedback that triggers protective shutdowns when necessary. This ensures high reliability and safety in demanding machine environments. This drive is designed to support industrial spindle applications requiring precision, protection and stable performance.
