Product Description:
The Bosch Rexroth Indramat KDA 2.1-150-3-LQI-W1 is a spindle drive that is built to offer high precision and efficiency alongside flexibility of action.
This model is designed to support high-performance machining and automation loads, has a rated current of 150 A. It is also capable of delivering maximum currents of about 300 A, where extra torque or acceleration is needed. It can be programmed to operate three axes, which is why it is effective with more complicated multi-axis machine setups. The drive runs on a three-phase power supply and has a current range of 3 x 400 /460 V AC, and its tolerance is +10 to -15%. It boosts a frequency range of 50/60 Hz, compatibility, and interchangeability with international power standards to be used in a wide international applications. Cooling is also controlled using a liquid-cooled system (LQI), which offers good thermal control, as well as enables the unit to operate successfully under harsh load conditions. The protection level is IP00, which states that it is installed in an enclosure or a protected electrical cabinet to protect it against environmental factors. It has flexibility in communication and supports analog, digital, and SERCOS interfaces, allowing it to be integrated with old-style and new automation networks.
The KDA 2.1-150-3-LQI-W1 uses both resolver and encoder feedback interfaces, providing the extremely accurate position and speed monitoring that is essential to spindle motion at high accuracy. The system control electronics are fed by a 24 V DC control voltage to achieve a stable start and operation. The drive has a switching frequency of 6-8 kHz, which allows the spindle dynamics to be controlled smoothly and responds quickly. It is approximately 24 kg and can be mounted to a panel or chassis with strong installation possibilities. This drive is a reliable product in high-demand machining machines, with an operating temperature range of 0 °C to +45 °C, and derating intensity to over 40 °C.
