Product Description:
The Bosch Rexroth Indramat KDA 2.1-050-3-LYS-W1 Drive supports additional encoder feedback for enhanced synchronization and monitoring and ensures consistent operation within a controlled temperature span. It provides a convenient RS-232C serial interface for communication and reliably ensures a continuous rated current of 50 amperes.
The KDA 2.1-050-3-LYS-W1 drive can briefly withstand a surge of 70 amperes of current and gives the ability to handle demanding moments such as rapid accelerations effectively. To ensure it maintains safe internal temperature during operation, air is pushed across the thermal sink by a dedicated fan to actively drive away the excess heat. It can survive extreme climates such as from cold -30 degrees up to sweltering 85 degrees without losing its reliability. Its enclosure offers only limited defense against intrusion and prevents only large objects from entering. It is built with an internal safeguard that prevents damage if electrical or mechanical stresses exceed safe levels. It is suitable for use in environments with expected moisture fluctuations as its permissible humidity is defined as F per DIN 40 040. In this module, commands for rotation speed are communicated via the SERCOS digital interface which is a standardized network protocol.
The KDA 2.1-050-3-LYS-W1 drive responds with little deflection or compliance under force and it resists deformation and allows precise, steady operation. The alternating current supply source for heatsink blower is 220V and can work with either 50 or 60 cycles per second. It is made to offer sustained output without needing to cycle down which emphasizes reliability in long duration duty. Its DC bus operates at 300 volts and serves as the backbone for energy transfer between rectifier and inverter sections.
Frequently Asked Questions about KDA 2.1-050-3-LYS-W1:
Q: How does the KDA 2.1-050-3-LYS-W1 handle temporary current spikes?
A: It tolerates short bursts of higher current to manage rapid load changes. This protects the spindle during acceleration and prevents performance drops under stress.
Q: What benefit does auxiliary encoder feedback provide in this drive?
A: It improves synchronization between the motor and control system. This results in finer accuracy in spindle positioning and speed stability.
Q: Can this drive operate reliably in fluctuating workshop climates?
A: Yes, it can withstand both moderate operating heat and extreme storage conditions. This ensures dependability even in facilities without strict climate control.
Q: Why is the RS-232C port important in industrial use?
A: It allows straightforward setup, parameter tuning, and diagnostics with minimal hardware. This makes integration into legacy control systems easier.
Q: Does the KDA 2.1-050-3-LYS-W1 require a specific mains frequency?
A: The blower can operate on either 50 Hz or 60 Hz supply. This flexibility simplifies installation in regions with different grid standards.
