DMA 004A 1101-D

The DMA 004A 1101-D from Bosch Rexroth Indramat is part of the DMA Servo Drive Modules series, designed to deliver precise control and robust performance in three-phase drive applications. With a 24 VDC current input of 1.0 A and an Input Voltage rating of 670 V, this module efficiently interfaces with industrial inverter systems. Its Output Voltage of 400 V ensures stable power delivery to connected servo or asynchronous motors. As a member of the Servodyn-D family, the DMA 004A 1101-D excels in motion control tasks, offering high-speed switching and reliable modulation for demanding automation environments.

The DMA 004A 1101-D features a maximum current rating of 4 A at a 2 kHz switching frequency, with peak currents reaching 5.6 A under both overload and continuous conditions at 4 kHz. At 8 kHz, the module sustains a peak of 5.6 A, with rated currents of 1.7 A for overload and 3.3 A for continuous load. Temperature derating applies between 45 °C and 55 °C, at 0.15 A/°C for 4 kHz operation and 0.08 A/°C at 8 kHz. The module supports a SERCOS interface with fiber-optic connectivity, real-time processing and multi-vendor interoperability, alongside a standard encoder for precise feedback.

With an air-cooled design and a recommended clearance of 100 mm on all sides, the DMA 004A 1101-D ensures efficient heat dissipation and longevity. Its robust construction carries an IP20 protection rating, and the compact footprint of 517 × 50 × 288 mm at 7.3 kg simplifies integration into switch cabinets. Peak power loss is limited to 94.3 W, minimizing energy waste. Global shipping is backed by a one-year warranty, underscoring the module’s reliability. In industrial applications, this drive module enhances system efficiency, reduces maintenance intervals, and delivers precise motor control under varying load and temperature conditions.
