Product Description:

The HMD01.1N-W0020-A-07-NNNN-AA is a double-axis drive controller produced by Bosch Rexroth Indramat for coordinated servo applications. As a closed-loop power stage, it controls two servomotor axes in machinery that requires synchronized motion, such as handling gantries and packaging stations. The unit communicates with higher-level automation systems through the standard drive bus and converts DC bus energy into regulated phase currents for both axes. This dual-axis format supports coordinated motion in compact machine layouts where two related axes share one controller platform. That arrangement is suited to machines that need synchronized starts, stops, and speed changes between paired axes.

Thermal management uses internal air cooling with an integrated blower, so the built-in fan moves air across heat sink surfaces without external ducting. The controller operates on a nominal bus level of DC 700 V, which matches supply modules used in multi-axis cabinets. During acceleration peaks, each axis can draw up to 20 A of effective current, and the drive regulates this load when cabinet airflow is sufficient. The housing has IP 20 protection, so the unit must be installed inside a control enclosure to prevent contact with live parts and to limit dust exposure. The controller is Design Version 1.

The unit is Line Version 1, so its mechanical dimensions and connector layout follow the first HMD platform format. It has no additional design features, so no auxiliary encoder supply, I/O extension, or safety relay is included. It also has no integrated power supply, so a separate supply module provides the DC bus energy. This arrangement keeps the axis electronics separate from the supply section in multi-axis cabinets. The same cabinet can therefore use a common power source while supporting multiple coordinated drive modules.
