Product Description:

The DM 15K 9301-D servo drive is produced by Bosch Rexroth Indramat for the DM Servo Drives series. The module converts DC link energy into regulated three-phase output for industrial motors that require precise current control during automated production cycles. Command data enter the unit through a CAN bus setpoint interface that follows the CANopen/CANrho protocol, giving higher-level controllers deterministic access to drive parameters. Because the unit supplies only torque and velocity loops, any absolute position handling remains with the machine PLC or motion controller.

The electrical section is rated for a continuous armature current of 11 Arms at a 4 kHz control frequency. For short acceleration events, the permissible current rises to 15 Arms in closed-loop operation and to 18 Arms when the regulator operates open loop, providing headroom for momentary load peaks. Cooling air moves across the heat sink, and output capability drops by 0.32 A per kelvin as ambient temperature rises. The housing carries an ingress protection rating of IP20, so it must be mounted inside a control cabinet. During maximum thermal load, the converter dissipates 121 W of power, which helps when planning cabinet ventilation and heat removal.

The drive occupies only 50 mm of panel width, which helps simplify multi-axis lineups in compact cabinets. It weighs 6.0 kg, which keeps handling demands modest during DIN rail mounting. Control electronics are energized by a 24 V auxiliary supply that draws just 0.89 A, reducing the load on cabinet power supplies during drive enable sequencing. The resolver feedback channel processes rotor angle data with a resolution of 12 bits, which supports smooth velocity loops even though the unit does not provide positioning control.
