Product Description:
The Bosch Rexroth Spindle drive KDA 2.1-150-3-LPS-U1 is designed for industrial automation use. The drive delivers reliable operation via its electrical characteristics, connection options, and environmental limits. The protection level of the spindle drive is IP10. It must be installed inside a closed control cabinet.
The continuous current rating of the KDA 2.1-150-3-LPS-U1 spindle drive is 150 A. It operates on a DC link voltage of 300 V. This drive has an integrated cooling system with a heatsink blower. The blower operates with 115VAC. It maintains internal temperature when maintained over a long usage period. This spindle drive has a speed input that is controlled by a SERCOS fiber optic connection. This connection can be found at terminal X4 in order to facilitate accurate and prompt communication. The KDA 2.1-150-3-LPS-U1 spindle drive feedback is handled via a 15-pin connection at terminal X3. There is also a second encoder input at X5 to which are connected the spindle, or second motor feedback signals. These input levels contribute to the accurate control of the motor positions. The RS-232C serial interface is available at terminal X6 to communicate and monitor data. It also has the capability of sending an incremental encoder signal when needed. The X2 terminal has analog and digital control inputs and outputs that can be used to connect the machine controllers. These communication channels allow a flexible system integration and motion control systems.
The operating temperature range of KDA 2.1-150-3-LPS-U1 spindle drive ranges between +5 °C and +45 °C. It favors storage temperatures of 85 °C to -30 °C. Maximum installation altitude without derating is 1000m. The drive is constructed to suit humidity requirements according to standard Class F of DIN 40040. Every connector and terminal is clearly marked to ensure easy fixing and maintenance.
Frequently Asked Questions about KDA 2.1-150-3-LPS-U1:
Q: What are the design implications of 150 A current in KDA 2.1-150-3-LPS-U1 spindle drive?
A: The KDA 2.1-150-3-LPS-U1 spindle drive must manage high conductor temperatures. It requires carefully sized busbars and cabling to avoid voltage drop and overheating.
Q: Why does KDA 2.1-150-3-LPS-U1 spindle drive use SERCOS input?
A: The KDA 2.1-150-3-LPS-U1 spindle drive uses SERCOS for deterministic, fiber-optic control. This reduces EMI and enables precise speed command synchronization across axes.
Q: What is the benefit of dual encoder inputs on KDA 2.1-150-3-LPS-U1 spindle drive?
A: The KDA 2.1-150-3-LPS-U1 spindle drive supports simultaneous motor and spindle feedback. This allows fine-tuned torque control or tandem motor feedback handling.
Q: Why is the RS-232C interface still present in the KDA 2.1-150-3-LPS-U1 spindle drive?
A: The KDA 2.1-150-3-LPS-U1 spindle drive uses RS-232C for low-level diagnostics. It ensures access when higher-layer buses are unavailable or system faults occur.
Q: How does the internal blower affect KDA 2.1-150-3-LPS-U1 spindle drive cooling?
A: The KDA 2.1-150-3-LPS-U1 spindle drive uses a forced-air heatsink blower. Its efficiency depends on ambient airflow design and control cabinet thermal dissipation strategy.
