DM 4K 1301-D

The Bosch Rexroth Indramat DM 4K 1301-D from the DM Servo Drives series features a robust 670V input voltage supply configuration and is engineered for seamless integration with three-phase synchronous and asynchronous motors. This Servodyn-D inverter module delivers a DC link voltage of 670V at dual switching frequencies of 4 kHz and 8 kHz under ambient conditions up to +45 °C. Control accuracy is assured by a built-in 12-bit Resolver encoder delivering high-resolution feedback, while the native SERCOS interface provides deterministic, real-time communication between controllers, motion devices, and I/O modules. The modular architecture combines dedicated supply and axis modules in a compact 50 mm width.

Reliability is maximized by an air cooling system that efficiently dissipates 96.5 W of heat generated during continuous operation. The axis module sustains a rated current of 1.4 A rms and a peak current of 6.6 A rms, with a thermal derating coefficient of 0.15 A/K from +45 to +50 °C to protect semiconductor components. Auxiliary power requirements are modest, drawing just 0.89 A from the 24 VDC supply. Housed in an IP20 protection class enclosure and certified to climate category 3K3 per EN 60 721, the unit resists dust ingress and moderate humidity in industrial environments.

At a net weight of 6 kg, the DM 4K 1301-D balances lightweight design with a standard feature set, eliminating the need for additional functions or retrofits. Backed by a one-year warranty and global shipping support, this inverter module offers a dependable, scalable solution for mid- to high-performance automation tasks.
