Product Description:

The DMA 04A 1301-D servo drive module is built by Bosch Rexroth Indramat and belongs to the DMA Servo Drive Modules series. This unit occupies a single slot in a multi-axis rack and acts as the power and control interface between the DC link supply and rotary or linear actuators. In an automation cell, the module governs torque, velocity, and position for synchronous and asynchronous motors, allowing coordinated axis motion through its integrated control electronics. Because the power stage and control functions are combined in one rack module, it supports closed-loop axis operation in compact multi-axis systems.

Heat is removed by backplane air cooling, so convective air drawn through the rear of the rack maintains semiconductor temperature without external fans on the module itself. Motor feedback is accepted through a resolver, allowing rotor angle detection across the full speed range. Command and diagnostics are exchanged over the SERCOS interface, so the drive can synchronize with other axes using deterministic timing. Cabinet space usage is predictable because the housing has a width of 50 mm, which allows multiple modules to share compact enclosures. That narrow width also helps maintain high axis density when several controlled motors are installed in the same rack. Within the control topology, the module is part of the Servodyn-D series and works with matching supply units and parameter sets.

The unit is described as a three-phase module for synchronous and asynchronous motors, so it can deliver balanced power to both permanent-magnet and induction designs without hardware changes. No optional expansion boards are fitted, and the drive has no additional functions. The hardware level is the standard variant, which matches the baseline configuration used for this model. Without add-on boards, the internal layout remains limited to the base drive functions and the standard control path.
