Bosch Rexroth Indramat's DMA 140D 1201-D is a three-phase backplane module specifically designed for the fully digital Servodyn-D inverter system series. It showcases a compact, modular structure and mirrors the construction style of IGBT output stages. The module, compatible with brushless asynchronous and synchronous motors, offers position control. Equipped with an efficient air-cooling system, it maintains effective temperature regulation. With a maximum current of 140 kHz and module width of 200 mm, it features a 32-bit resolution SERCOS interface—a powerful processor board allowing full digital control of position, speed, and current. The SERCOS interface, included with a gear encoder, enables the interconnection of the module with fiber optics. Without additional functions or variants, this module is versatile for use in Servodyn-D hardware whether with asynchronous and built-in motors, gear, or absolute encoders.
