Product Description:

The HMD01.1N-W0012-A-07-NNNN is a double-axis drive controller from Bosch Rexroth Indramat in the HMD Double Axis Drive Controllers series. It governs two servo channels through shared DC-bus energy so coordinated positioning, speed, and torque loops can be executed in machine tools, packaging stations, or material-handling cells. The unit converts stored DC power into regulated three-phase outputs while reading motor feedback to maintain commanded motion. Its compact format supports cabinet installation without increasing the automation footprint. By handling two axes in one housing, it helps reduce the number of separate drive modules in compact cabinets.

The thermal design relies on internal air cooling generated by an integrated blower, eliminating external ducting and keeping components within their allowable temperature range. During acceleration events, the power section can deliver an effective peak phase current of 12 A, giving each axis short-term torque headroom without overstressing semiconductor devices. The housing carries an IP20 protection rating, so live parts are finger-safe but the controller must be installed inside an enclosure for dust and liquid protection. A common DC link operates at a nominal potential of DC 700 V, which matches compatible supply modules and reduces copper losses across the intermediate circuit. The shared bus arrangement supports both channels from the same intermediate circuit, which helps keep the power stage layout compact.

The controller is Design Version 1 and Line Version 1. It has no additional design features, so it omits extras such as safety relays or encoder emulation ports. It also has no integrated power supply, so a separate HMV or HCS module must furnish the DC-bus voltage. This arrangement allows the supply section to be selected independently for the connected axis load.
