Leistritz DDS02.1 - A/W100 Digital Servo Drive

Product Introduction DDS02.1-A/W100 is a modular digital AC servo drive from Bosch Rexroth (Indramat) in the DDS02.1 series. It is used to drive synchronous/ asynchronous servo motors and is compatible with a multi-axis shared DC bus architecture. The rated current is 100 A, with external air cooling (A) / internal cabinet air cooling (W). It is suitable for heavy industrial automation and machine tool applications.
