Product Description:
The digital spindle drive, Bosch Rexroth Indramat KDA 2.1-150-3-LQD-U1, is a member of the KDA series and is intended to precisely manage high-performance servo systems.
This model is capable of up to 2 axes control and also has a rated current of 150 amps. The drive is powered by a 3-phase AC power of 230/400 V, and this enables it to be used with the standard voltages. It operates nominally at 50/60 Hz, typical of industrial power systems. It is designed to fit into multi-axis CNC and automation systems in which rapid response and accurate control are essential. Cooling consists of an integrated air blower operated by means of a 115 VAC source to keep air moving over the heat-generating elements at all times to enable stable operation. This makes the unit applicable to locations where liquid cooling is not applicable and yet supports high performance. The drive can be installed in a cabinet and has a weight of about 22 kg. It has a nominal DC voltage of 300 VDC is conducive to stable power distribution. It has complete digital control with parameterization through onboard keypad or through serial access, which allows flexibility of setup, tuning, and diagnostics.
SERCOS, a high-speed digital interface that employs real-time communication and is widely utilized in motion control systems, is used to communicate with the rest of the automation system. It is also compatible with resolver and incremental encoder feedback, enabling use with many different motors and positioning systems. In situations when more accuracy is required, it additionally incorporates a 1 Vpp sinusoidal signal, which serves as supplementary feedback and an auxiliary encoder input. With an IP10 protection grade at the housing level, the module has to be protected from the elements in a closed control cabinet.
