Product Description:

The HDS02.1-W040N-HA04-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Acting as an axis module in DIAX04 multi-axis platforms, it manages current and velocity loops for servo motors used in machining centers, printing lines, and material-handling cells. By translating analog reference signals from a higher-level motion controller, it adjusts output power to the connected motor and maintains synchronized closed-loop operation within the automation cell. This operating role makes it suitable for systems that separate motion control functions from the power stage while still requiring accurate axis response.

The unit uses an analog command interface, so velocity or torque references arrive as ±10 V signals rather than through a digital network. Its power section can deliver 40 A continuously, providing adequate headroom for mid-range axes that require frequent acceleration and deceleration. Thermal energy is extracted by a built-in air blower, which supports stable cooling inside the housing during sustained load. Full-load performance is available in ambient temperatures from +5 to +45 °C, and operation above that range follows a controlled derating curve. The enclosure has an IP 10 rating, so it should be mounted inside a protected electrical cabinet away from conductive dust and accidental contact.

When cabinet temperature reaches +55 °C, the controller can still operate at reduced current instead of shutting down immediately. Windings and power components use Class C insulation, which supports higher internal temperatures during operation. Installation is permitted up to 1000 m above sea level without a change to rated current or switching frequency, covering most industrial locations. The controller is part of the DIAX04 family and is identified as Line 02 and Version 1. It also tolerates storage or transport temperatures from -30 to +85 °C when moisture is controlled, helping protect electrical components during non-operating periods.
