DMA 140D 1103-D

Product Description

The DMA 140D 1103-D is a three-phase module for asynchronous and synchronous motors, suitable for backplane modules in the fully digital inverter systems from the Servodyn-D series. This and the inverter are manufactured by Bosch Rexroth and are ideal for the modular inverters in this series. The DMA 140D 1103-D features a maximum current of 140 kHz, the exact value cf. technical data. The module width is also 200 mm, while the air cooling system is fitted with backplane mechanics to fit the module's nature. The air cooling system is included for temperature regulation and preventing overheating.

The DMA 140D 1103-D has a SERCOS interface and a standard encoder interface when it comes to its setpoint interface. The SERCOS interface makes this backplane three-phase module send signals quicker than those that feature analog interfaces since it features a 32-bit signal processor. Inverter modules with a SERCOS interface like DMA 140D 1103-D can be interconnected using fiber optics. The fiber optics can also close the circuit using the PC or control as the master. A single fiber optic will be used to connect the module to the neighboring module on the left side.

The DMA 140D 1103-D SERCOS interface features real-time processing, free drive, and control combinations regardless of the manufacturer, and optical fibers resistant to a fault. The DMA 140D 1103-D does not feature any additional functions, but as for the variants, it also features a master/slave drive.  The drives are in the same cable and have no power over the other. This three-phase module with backplane mechanics is suitable for the inverters manufactured by Rexroth for the Servodyn-D series. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
