Product Description

Bosch Rexroth is a Germany based manufacturer of industrial motion control products. The company supplies equipment to various types of industries including the printing industry, the packaging industry, the metal and woodworking industry, and the automotive industry. Their products can be purchased from Wake Industrial with a one-year warranty. 

The Servodyn-D inverter systems are produced by the company for achieving high positional accuracy in industrial servo motors. In addition, they also control the motor’s speed and flow of current to the motor. The inverters come with a basic configuration that can be extended by adding further modules. The DMA 085B 6311-D is one such module that is used with the Servodyn-D inverters. The module is used for position, speed, and current control in servo motors. This model supports the SERCOS interface that can be used with the sine and cosine encoders. The sine encoders operate at a 50 kHz frequency and come with EXE while the cosine encoders operate at an 800 kHz frequency. The DMA 085B 6311-D operates on 670 Volts regulated DC link voltage and requires a 1.35 A current for operation.

The DMA 085B 6311-D has a 100 mm width and weighs around 11.5 kg. The system’s maximum current is 86 A and the rated current is 22 A when the operating frequency is 4 kHz. If the frequency is ramped up to 8 kHz, then the maximum current decreases to 64 A and the rated current rises to 47 A. These performance parameters remain consistent in an optimum temperature range (0 ᵒC to 45 ᵒC) after which there is a power derating of 1.25 A/K. Overall, the DMA 085B 6311-D proves to be a very useful subsystem that can enhance the motion control capabilities of the Servodyn-D AC inverter systems.
