Product Description:
The KDA 3.2-050-3-LPS-U1 is a modular spindle drive unit engineered by Rexroth Indramat for closed-loop motor control. It features a digital fiber-optic SERCOS interface and supports precise velocity as well as position control via digital commands. This drive delivers a rated current output of 50 A and it operates on a regulated 300 VDC DC bus system.
The KDA 3.2-050-3-LPS-U1 drive features a serial RS-232C interface for parameter handling and diagnostics. It includes an auxiliary encoder input along with the supported high-resolution feedback system to handle secondary feedback for precise positioning and C-axis operations. The drive manages cooling through a built-in forced air blower system that requires a 115 VAC supply at 50/60 Hz frequency and it dissipates heat externally through the rear-mounted heatsink. Its design supports airflow of 32 liters/second at 30 Pascals and the cooling system requires usage in clean environment, as it senses temperature and forces the drive to shut down in case of insufficient airflow. The KDA 3.2 drive operates within an ambient temperature of 41 °F to 113 °F and its permissible installation altitude is up to 1000 meters above sea level with humidity limit of 70% RH without condensation. It meets IP10 protection standard and requires vertical enclosure mounting.
The KDA 3.2-050-3-LPS-U1 drive provides electrical connections via standardized terminal blocks and D-sub connectors. Its terminal X8 supports motor phase outputs at A1, A2, A3 and DC input at L+, L-, while the terminal X12 supports motor thermistor connection and the interface X2 is a 37-pin point that handles control inputs and analog I/O. The unit supports simple module replacement and its parameters are stored in AS module. It requires a minimum of 10 mm² grounding conductor and it weighs 16.6 kg, excluding the accessories.
Frequently Asked Questions about KDA 3.2-050-3-LPS-U1:
Q: What advantage does the fiber-optic SERCOS interface offer in KDA 3.2-050-3-LPS-U1?
A: The fiber-optic SERCOS interface minimizes signal interference and allows high-speed, real-time communication with controllers. This ensures superior precision in closed-loop motor control.
Q: Why does the KDA 3.2-050-3-LPS-U1 include an auxiliary encoder input?
A: The auxiliary encoder input is essential for C-axis operations or dual-loop positioning. It enhances feedback resolution beyond the primary encoder’s capability.
Q: What’s the role of the built-in air blower in KDA 3.2-050-3-LPS-U1?
A: The blower maintains thermal stability by expelling internal heat through a rear heatsink. Its airflow capacity ensures the drive operates reliably in intensive duty cycles.
Q: Why does the drive use a 300 VDC regulated DC bus system?
A: A 300 VDC system allows consistent voltage delivery to the motor. It also enables better performance control across variable loads and speeds.
Q: How does the RS-232C interface benefit the KDA 3.2-050-3-LPS-U1?
A: It supports external parameter adjustment and real-time diagnostics. This aids in maintenance, troubleshooting, and system tuning without interrupting operation.
