The DMA 085B 4201-D is a three-phase module that is installed in the Servodyn-D inverters. The Servodyn-D invertersystem is used for speed control and highly precise positioning of industrial motors. The invertersystem has a modular structure and its mechanics have been optimized to deliver maximum power output. The system supports cold module engineering because of its backplane module. The DMA 085B 4201-D module can be used with the SR, SF, and synchronousmotors where it enables highly accurate position and speed control. The module can utilize the single turn and multi-turn absolute encoders. In the case of multi-turn absolute encoders, a 32-bit resolution can be achieved whereas the single-turn absolute encoders provide a 20-bit resolution. The module also supports the SERCOS interface that can be utilized with the cosine and sine encoders.
The DMA 085B 4201-D has an 8 A rated current and 63 A peak current at 8 Hz frequency. At a 4 Hz frequency, the rated and peak current values are 22 A and 86 A respectively. With a width of 100 mm, the device has an 11.5 kg weight. Two separate blowers are provided for effective heat dissipation. The maximum continuous load current is 64 A and the rated continuous load current is 47 A. The ideal temperature range for the system’s operation is between 0 ᵒC to 45 ᵒC beyond which there is a power derating of 1.25 A/K. Overall, the DMA 085B 4201-D is a very effective subsystem for motion control in industrialmotors.
