Product Description:
The KDA 3.1-050-3-DPI-U1 from the KDA Spindle Drives series is engineered by Rexroth Indramat for precision control in high performance spindle systems. It guarantees the reliability in numerous compulsive tasks in CNC equipment and manufacturing machines. The drive has a digital 16 bit parallel interface to the speed command channel with precise speed and performance control.
The KDA 3.1-050-3-DPI-U1 spindle drive contains the specified value of output current expected to be a constant 50 amperes when the load varies. Its main input line is a three phase electrical connection that supports balanced power distribution. The drive cooling system is furthered using forced air ventilation by using a heat sink mounted blower. Its blower is powered by the 115V supply with a frequency of 50-60 Hz. The spindle drive has an auxiliary interface with incremental encoder output that gives position feedback. It has an auxiliary encoder input port which is used in supporting both the synchronized and auxiliary processing of signals. The KDA 3.1-050-3-DPI-U1 spindle drive digital communication system is created at a 9 pin terminal block to ensure the use of a stable signal. Its environmental flexibility is achieved due to an operating temperature of 0°C to +45°C. The drive has been capably configured to be operational at altitudes as high as 1000 meters above the ocean. Its IP20 enclosure rating is that which guards the internal parts against solid foreign material bigger than 12.5 mm.
The KDA 3.1-050-3-DPI-U1 spindle drive is used in areas with a relative humidity of less than 95 percent without condensation. It assists in avoiding internal corrosion or electrical breakage from long term operation. The drive internal DC link that is stabilized at 300 volts adds to efficient energy performance.
