Product Description:

The HDS03.1-W100N-HA03-01-FW is a drive controller manufactured by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. It is used in automation systems to modulate power for servo axes, matching motor torque and speed with motion profiles from a PLC or CNC. By translating reference values into regulated current, the unit helps synchronize multiple axes in industrial machinery where coordinated positioning and velocity control are required. This type of control supports repeatable motion in equipment that must hold speed accurately while responding to changing load conditions.

This controller belongs to the DIAX04 family and is part of Line 03 with Version 1. Command signals reach the device over an analog interface, so ±10 V speed or torque references can be issued directly from standard motion cards. Because the command input is analog, the controller can work with motion hardware that sends direct voltage references instead of serial control commands. The power section is rated for 100 A continuous output, enabling it to drive large synchronous or induction motors without external amplification stages. Thermal management relies on a built-in air blower; the integral fan forces air across heat sink fins to control internal temperature. Electrical ingress protection is limited to IP10 per DIN 40 050, so the controller must be mounted inside a cabinet that provides added shielding from dust and accidental contact.

Continuous duty is permitted from +5 ... +45 °C. At higher ambient temperatures, output derating is required, and operation can continue up to +55 °C. Storage and transport can occur between -30 ... +85 °C without damaging electronic or magnetic components, provided condensation is avoided. Reliable dielectric spacing is maintained up to 1000 m above sea level, making the controller suitable for most factory elevations. Windings and insulation materials are classified as C under DIN VDE 0110, allowing high internal temperatures during heavy cyclic loads. Avoiding condensation during storage helps protect insulation distances and metal surfaces before the unit is installed. Cabinet ventilation must keep ambient conditions within the permitted range so the blower can remove heat effectively.
