Product Description:

The DM 15K 5111-D servo drive is manufactured by Bosch Rexroth Indramat as a member of the DM Servo Drives series. The unit functions as a positioning controller, translating motion commands from higher-level PLCs into regulated phase currents for synchronous servomotors used in automated handling, packaging, and assembly equipment. By integrating signal processing, power electronics, and feedback evaluation in one compact housing, the drive forms the core power stage that closes the velocity and position loops in industrial automation cells. It is intended for servo axes that require coordinated acceleration, deceleration, and repeatable positioning under continuous control.

The drive’s internal electronics draw 0.89 A from the 24 V auxiliary bus, supplying logic circuitry, gate drivers, and the encoder interface. In closed-loop operation at an 8 kHz switching frequency, it can source a steady phase current of 7.4 Arms, while transient overloads are supported up to 15 Arms for rapid acceleration events. Continuous current capability drops by 0.23 A/K as ambient temperature rises, so cabinet thermal planning must account for warmer operating conditions. An air-cooled construction moves heat away from the power stage without external liquid circuits, and the mechanical envelope remains only 50 mm wide for dense rack layouts. Touch-safe terminal covers provide a protection level of IP20, and the drive receives velocity or position setpoints from the supervisory controller through digital control signals.

The module has a mass of 6.0 kg, and its cast housing withstands assembly-line vibration and shocks up to 15 g. Under worst-case switching and conduction losses, the power stage dissipates 121 W, so the cabinet must remove that heat during continuous operation in the 3K3 climatic category. The optional MTG feedback channel delivers 32-bit position data, whereas the STG alternative supplies 20-bit resolution for applications with lower feedback requirements. These feedback options allow the control loop to match the accuracy needs of the connected axis. The drive is suitable for sealed control cabinets that use forced air to manage internal temperature.
