Product Description:
The DMA 140D 5311-D is a servo drive module produced by Bosch Rexroth Indramat within the DMA Servo Drive Modules series. As a three-phase unit for synchronous and asynchronous motors, it controls one mechanical axis and accepts 24 V control signals that coordinate position loops with a resolver feedback interface. The air-cooled backplane design, two integrated fans, and a 200 mm housing width allow cabinet mounting without external heat sinks, making the drive a compact element in industrial automation cells.
The module’s logic supply needs 1.58 A at 24 V, so control wiring can be sized for low current while keeping the digital interface stable. Its factory switching frequency is 8 kHz; at this rate the current regulator delivers a continuous armature current of 60 Arms in closed-loop mode, supplying smooth torque to the motor. For short overload intervals, the open-loop limit rises to 117 Arms, giving acceleration reserves when starting heavy loads. Thermal derating between 45 °C and 55 °C is 1.75 A/K, so current setpoints must be reduced by that amount for each kelvin in that range to keep semiconductor temperatures within safe limits.
The DC link is fed from a shared supply; its non-regulated voltage reaches 715 VDC and is actively stabilized to 670 VDC during regenerative events, supporting consistent motor volt-per-hertz ratios. Internal dissipation peaks at 700 W, a value matched by the backplane airflow so cabinet extraction fans can be selected accurately. With a mass of 19.3 kg, the unit remains manageable during installation and provides the stiffness needed for reliable connector seating. The standard variant uses 12-bit resolver resolution, providing adequate position granularity for most mid-range motion axes while remaining compatible with legacy feedback wiring.
