Product Description:
The DM 15K 1301-D is a DM Servo Drives series module manufactured by Bosch Rexroth Indramat. It conditions power and communication between motion controllers and servo motors used in industrial automation cells for precise speed and torque regulation. In operation, it links incoming command data with motor feedback so the drive can regulate acceleration, holding torque, and speed changes during repetitive machine cycles. The unit is suitable for medium-power linear axes, indexing tables, and packaging stations that require tight current regulation and minimal panel space.
This module draws a control supply of 0.89 A at 24 V to power its internal logic and gating circuits. It can deliver a peak phase current of 15 Arms when operated at a 4 kHz carrier frequency under closed-loop control, while the permissible peak falls to 11 Arms at 8 kHz because of switching losses. Thermal headroom above 45 °C is expressed by derating slopes of 0.32 A/K for 4 kHz operation and 0.23 A/K for 8 kHz operation, so usable output current decreases linearly within the 45 to 55 °C cabinet range. At full output, the converter generates up to 121 W of internal power loss that must be removed by cabinet airflow. The drive accepts velocity commands through a SERCOS interface and closes the current loop with feedback from a resolver that offers 12-bit resolution.
Heat is removed by forced air cooling, a scheme compatible with the drive’s compact mechanics that measure 50 mm in width and 430 mm in height for dense multi-axis racks. This format also supports differential encoder channels up to 1 MHz for incremental encoders, along with 50 kHz for sine encoders and 800 kHz for sine/cosine evaluation. The resolver interface coexists with these digital channels, giving the controller flexibility in retrofit installations and mixed-feedback systems. The 50 mm face simplifies side-by-side mounting without additional spacing.
