Product Description:

The HDS03.1-W100N-HA05-01-FW is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Within automated production cells, it supplies regulated power to multiple servo axes, translating motion commands from a central PLC into precise current and voltage profiles that keep motors synchronized with commanded speed and position. For axis commands, the controller uses an analog reference channel that matches earlier DIAX04 family drives, allowing retrofit in existing racks. Because the command path is analog, the unit fits installations that were designed around conventional setpoint wiring rather than digital fieldbus control. This operating role makes it suitable for coordinated servo applications that depend on stable current regulation during acceleration, speed control, and position holding.

Its continuous output capability reaches 100 A, so the unit can energize high-torque servomotors without clipping current loops. Heat generated by this load is removed by a built-in air blower that circulates cabinet air across the power stage. The housing meets IP10 protection, giving basic guarding against accidental finger contact while relying on the cabinet for additional ingress resistance. Because of that enclosure level, the controller is intended for protected installation inside a suitable cabinet rather than open mounting on the machine. Reliable electronic behavior is maintained when ambient temperature stays between +5 to +45 °C, which is the normal operating range for full current output.

When the surrounding air reaches +55 °C, derating is required, and operation above 1000 m follows the same current reduction curve because reduced air density limits convective cooling. At higher temperatures or elevations, the controller cannot maintain the same continuous current as it can under nominal conditions. Windings and bus bars are insulated to class C according to DIN VDE 0110, permitting higher internal temperatures before thermal breakdown. During storage or shipment, the electronics can withstand temperatures from -30 to +85 °C without performance loss, which supports transport and unpowered storage in varying climates. The product is part of Line 03 and is version 1.
