The Bosch Rexroth Indramat DM 4K 9301-D is a servo drive from the DM Servo Drives series with a mass of 6.0 kg and a module width of 50 mm. It operates with a DC link voltage of 670 VDC regulated or 715 VDC non-regulated, and supports a maximum current of 6.6 Arms at both 4 kHz and 8 kHz open loop frequencies. The drive uses a resolver encoder interface and communicates via CANopen or CANrho protocols.
Internal Product Review
The DM 4K 9301-D is a Bosch Rexroth Indramat servo drive with CANopen / CANrho communication and a CAN Bus setpoint interface. Resolver feedback with 12-bit resolution supports dependable motion tuning and clean signal processing in demanding axis control. A 6.6 Arms maximum current at the 8 kHz factory switching frequency gives the drive a capable performance envelope.

Product Description:
The DM 4K 9301-D is a single-axis servo drive produced by Bosch Rexroth Indramat for the DM Servo Drives series. Within an automation cell it translates bus-level motion commands into three-phase output that governs a matched servomotor, supporting coordinated positioning, speed regulation, and torque control in packaging, assembly, and material-handling equipment. This role allows the axis to respond smoothly to changing loads while staying synchronized with the rest of the machine. Motion commands arrive through a CAN Bus setpoint channel, and network services conform to CANopen or CANrho for direct integration with higher-level controls. Position feedback comes from a resolver, whose 12-bit angle resolution supports the accuracy needed for general machine axes.
The internal DC link runs at 670 VDC when the upstream supply is regulated and 715 VDC when supply regulation is absent; these voltages energize the IGBT bridge that switches at 8 kHz. Closed-loop operation permits phase currents up to 4.0 Arms with one current-controller bandwidth or 2.5 Arms with the higher bandwidth setting. This lets the drive match different motor inductance and noise requirements without changing the main operating mode. The current settings support either faster electrical response or quieter operation, depending on the motor and application. The drive has no integrated safety or braking hardware.
The open-loop current ceiling is 6.6 Arms, enabling short torque bursts during transient overload or recovery. Thermal models place worst-case dissipation at 96.5 W, which can be removed with standard cabinet airflow. The module has a width of 50 mm, and the control electronics draw only 0.89 A from the 24 V auxiliary supply, leaving capacity on shared logic rails. Its mass of 6.0 kg supports multi-axis mounting where several drives share the same cabinet structure. With no optional boards fitted, all power, feedback, and bus connectors remain in the standard DM layout.
