Internal Product Review
The DM 30K 9301-D is a Bosch Rexroth Indramat servo drive with compact mechanics and air cooling. CANopen and CANrho communication pairs well with the resolver interface for accurate, stable control in integrated motion systems. Rated current up to 14 Arms at 4 kHz stands out as a strong performance point.

Product Description:
The DM 30K 9301-D servo drive is manufactured by Bosch Rexroth Indramat and belongs to the DM Servo Drives series. It provides the regulated current, position, and velocity control needed for precise industrial motion. Acting as the intermediary between a motion controller and a servomotor, the unit converts setpoint data into pulse-width-modulated power and monitors feedback to keep machinery synchronized during assembly, packaging, and material-handling tasks.
Its control electronics draw a 24 V auxiliary supply of 1.03 A, which powers internal logic and relay circuits even when the main bus is de-energized. Command data and diagnostics are exchanged over the dual-stack bus protocol CANopen and CANrho, while motion setpoints reach the power stage through the dedicated CAN Bus interface. Under closed-loop regulation at 4 kHz, the converter delivers 14 Arms. When an open-loop override is required, it can supply up to 29 Arms at the same switching frequency or 22 Arms at 8 kHz. A resolver interface with 12-bit resolution feeds rotor position information to the control ASIC, and the design omits additional application functions while supporting standard torque, velocity, and position modes.
Heat produced by the IGBT stage is removed through air cooling. At rated loading, the module dissipates a maximum of 156 W, so cabinet airflow must be sized for that heat loss. The housing follows the compact mechanics option and occupies only 50 mm of rack width, allowing dense multi-axis installations. Despite its small footprint, the drive weighs 6.0 kg, which adds thermal buffering and vibration stability. When clocked at 8 kHz in closed-loop operation, the continuous current capability falls to 9.7 Arms, and resolver signals are conditioned on board to avoid the need for external interpolation hardware.
