Product Description:
Strong spindle drives like the Bosch Rexroth Indramat KDA 2.1-150-3-LQD-W1 are appropriate for single-axis control under rigorous production requirements.
With prolonged operation, the drive's consistent 150 A output current proves to be dependable. To give shorter bursts of higher power to adjust torque or speed needs in three-phase motor control, it also offers a maximum output current of 225 A. The drive offers versatility across many regional power standards since it is made to operate within a 3-phase input voltage range of 220–230/380–460 VAC. It is expandable and compatible with a broad range of international power systems since it runs on a standard 300 V DC bus. The heatsink includes a separate 220 VAC blower; however, forced-air cooling is used for cooling. This arrangement makes this system able to provide steady thermal control when the system is under heavy, continuous loads. The drive's IP10 protection class means that to safeguard the operational environment, it has to be installed in an enclosed control panel.
The unit weighs around 16 kg and is 440 mm high, 100 mm wide, and 300 mm deep. Despite its extremely high current capacity, it is comparatively small and light. The drive is designed to support tachofeedback as standard, and resolver support is available to satisfy more sophisticated positioning needs. It has a line power interface, a motor connections interface, a feedback device interface, and a control signal interface, all simplifying integration into a complex system. Its speed of operation is managed through a common analog +/-10 V input, which makes integration with existing conventional control setups simple. It provides a 16-bit parallel digital entry path to high-resolution position instructions input, where precise synchronization is demanded, especially in system applications.
