Product Description:

The HDS03.1-W075N-HS76-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Integrated in a DIAX04 multi-axis system it supplies regulated power to a single servo axis and exchanges real-time status with the master control. The module’s function in industrial automation is to deliver closed-loop current and velocity control so that connected motors track programmed motion profiles under varying mechanical loads.

The controller communicates with higher-level motion CPUs through the optical SERCOS interface, allowing deterministic parameter exchange over a noise-immune link. It fits the DIAX04 rack format designated as line 03 and is released as version 1; no other versions are listed for this code. Continuous motor demand is handled with a rated output of 75 A, and excess heat is removed by a Built-in Internal Air Blower that circulates cabinet air across the heatsink. For enclosure integrity the unit carries a protection rating of IP 10 according to DIN 40 050, meaning it is guarded against large solid objects but requires installation in a closed cabinet. Reliable operation is specified between +5 °C and +45 °C ambient temperature.

When mounted up to 1000 m above sea level the controller retains full electrical performance; at higher elevations its current capability must be lowered to account for reduced air density. Insulation systems are built to class C per DIN VDE 0110, supporting elevated winding temperatures while the cabinet temperature may rise to +55 °C before the output must be de-rated. During storage or shipment the electronics tolerate a broad thermal window of -30 to +85 °C without damage to capacitors or solder joints, enabling spare units to be kept in unconditioned warehouses. These environmental margins, combined with the internal blower, give the axis controller the flexibility to serve machines that cycle through warm production floors and cooler maintenance areas.
