Product Description:
The DMA 030A 8001-D is a three-phase servo drive module produced by Bosch Rexroth Indramat within the DMA Servo Drive Modules series. It supplies and regulates synchronous and asynchronous motors in industrial automation systems by converting a common DC bus into controlled phase outputs for torque and speed control. Installed in a multi-axis backplane, the module supports coordinated motion across several axes while using only a narrow section of cabinet space. This layout helps keep power conversion close to the connected control hardware and supports compact drive assemblies.
The drive accepts a non-regulated DC link of 715 VDC and internally stabilizes it at 670 VDC for its IGBT bridge. Command input is handled through a 10-bit analog U/f characteristic reference from a PLC, allowing the output stage to follow an external speed or voltage request. Under open-loop conditions at a 4 kHz switching frequency, the output can rise to 35 Arms, while closed-loop operation at 8 kHz is limited to 12 Arms to reduce switching losses. The current rating decreases with a derating slope of 0.46 A/K at 4 kHz, so higher cabinet temperatures reduce the allowable output current and must be considered when matching the module to the motor and enclosure.
Logic and relay circuits draw 1.23 A from the external 24 V auxiliary supply, so the control power source must be sized for that continuous demand. Heat is removed by backplane air cooling, which means airflow must pass behind the module so the cabinet can carry away the stated heat loss during operation. The housing has a height of 504 mm and a mass of 7.3 kg, which suits standard cabinet installation and supports secure mounting when the enclosure structure is properly rated. The module does not include additional functions or an encoder port, which keeps the connection layout straightforward and leaves those features to other system components.
