Product Description:

The HDD02.2-W040N-HD12-01-FW is a dual-axis drive controller manufactured by Bosch Rexroth Indramat within the HDD Drive Controllers series. It is intended to regulate two servo axes in coordinated motion sequences, supplying controlled power to connected motors and relaying feedback to the higher-level automation system. By integrating power electronics and digital communication, the unit helps simplify cabinet layouts and supports precise positioning tasks on packaging lines, material-handling cells, and similar automated equipment.

This controller exchanges motion commands over the SERCOS fiber-optic interface, allowing deterministic cycle times and uniform parameter handling across a multi-drive network. For each axis, it can sustain a continuous output of 15 A/Axis when the pulse-width modulation frequency is 4 kHz, or 10 A (per axis) when the switching frequency is raised to 8 kHz; the lower current at the higher frequency limits thermal stress on the output stage. During rapid accelerations, the power stage delivers up to 40 A/Axis as peak current for brief intervals, giving additional torque without oversizing the motors. Internally, heat is removed by an internal air blower, so no external cooling ducts are required. The shared DC bus is rated at 40 A, and the logic section draws 40 W from the ±26 V auxiliary supply for control and feedback processing.

The housing has an IP10 protection category and is intended for installation inside a closed control cabinet free from falling objects. Operation is permitted up to 1000 m above sea level without derating. Ambient temperature can reach 55 °C when the output currents are reduced according to the derating curve. Each axis dissipates 110 W of power loss at continuous load, so cabinet ventilation must remove this heat along with losses from the signal-processing electronics. The unit contains two independent current sensors, one for each axis, to help maintain balanced performance across the drive pair.
