Product Description:
Designed to meet demanding industrial requirements, the Bosch Rexroth KDA 2.1-100-3-DQ0-W1 is a strong and dependable spindle drive suitable for continuous operation. It supports a 3-phase AC input configuration that ensures a stable and efficient power supply for industrial applications.
This KDA 2.1-100-3-DQ0-W1 spindle drive is built with a nominal continuous output current capacity of 100 A to provide consistent power delivery. It provides analog speed reference input of +/-10 V to enable precision adjustments. Its allowable ambient temperature lies between 0°C and 45°C to offer confidence in operating conditions. The system incorporates forced air cooling with a heat sink to maintain thermal stability during continuous operations. The KDA 2.1-100-3-DQ0-W1 spindle drive belongs to classification series 2 which ensures compatibility with standard Rexroth spindle modules. According to DIN 40 050 it carries an IP10 protection rating against accidental contact and large solid objects. Its cooling fan operates off a 220 VAC input supply that ensures that the drive remains efficient when used under prolonged duty. It uses 16-bit parallel digital resolution system to respond to its speed reference commands. The drive lacks an optional communication interface making the drive focused on primary spindle functionality. The altitude of installation can be up to 1000 meters with no compromises to its performance. The design tolerates relative humidity levels between 5% and 95% in non-condensing environments ensuring consistent use in different climates. The spindle drive utilizes SERCOS as the primary speed control interface for seamless communication with automation systems.
The KDA 2.1-100-3-DQ0-W1 spindle drive operates with a nominal DC link voltage of 300 V ensuring effective energy distribution. It supports an AC input frequency range of 50 to 60 Hz making it compatible with global power standards.
