Product Description:
Rexroth Indramat manufactures the KDA 2.1-100-3-LPD-U1 AC main spindle drive that is designed for milling, turning, drilling, and grinding. The drive is suitable for robots and other industrial automation systems requiring precise and dependable drive control.
The KDA 2.1-100-3-LPD-U1 AC main spindle drive has a continuous current rating of 100 A, which ensures steady spindle drive performance. In order to accomplish cooling, a forced cooling system employs a heat sink fan and a 115 V AC supply that operates at 50-60 Hz. The DIN 40 050 mandates an IP 10 protection level against electrical hazards. The main spindle drive provides consistent thermal and electrical performance at rated settings. The classification is F, and the maximal humidity level is 70%, as per DIN 40 040. The spindle drive meets the criteria necessary for automated manufacturing environments. Two motor feedback options and an encoder input for spindle monitoring are available as feedback options. A temperature of +5°C to +45°C is allowed for the spindle drive to operate in the surrounding environment. The KDA spindle drive can operate at a peak temperature of +55°C.
The KDA 2.1-100-3-LPD-U1 AC main spindle drive has dual feedback capability, which improves spindle and motor coordination. The interface selection promotes integration flexibility across a variety of control systems. The drive uses a DC bus voltage of 300 V to ensure consistent power delivery. The spindle drive is developed with a fan cooling system that ensures operational stability. The spindle drive has a SERCOS interface that accepts input for speed setpoint control and a parallel digital input with 16-bit resolution for position setpoint. The drive facilitates integration with machine tools and robotics used in industrial automation.
