Product Description:

The HDS03.1-W075N-HS80-01-FW is a drive controller produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. It functions as the power and motion-control unit inside DIAX04 multi-axis systems, converting drive commands into regulated current for industrial servomotors and actuators. Within an automation cell, the unit coordinates torque, speed, and position loops, allowing tightly synchronized motion between linked machinery and downstream processes.

The controller exchanges real-time setpoints with the master PLC over the SERCOS fiber-optic bus, so parameter updates and status data travel deterministically even in electrically noisy environments. When operating, the power section can deliver a continuous output of 75 A, allowing it to supply sustained motor current without thermal derating. Cooling is handled by a built-in air blower. This fan draws cabinet air through the heat sink to maintain semiconductor temperatures within safe limits. The metal housing has an IP 10 rating, which helps block contact with fingers and large objects while leaving airflow open for the blower path. Reliable function is specified for ambient conditions from +5 to +45 °C, covering typical plant floor temperatures without additional enclosure conditioning.

An installation altitude of 1000 m above sea level is supported before output derating begins, accommodating most factory mezzanines and elevated sites. If surrounding air climbs toward the derated ceiling of +55 °C, the load must be reduced or ventilation improved to stay within permissible thermal limits. During storage or shipment, the electronics tolerate a broader range of -30 to +85 °C, ensuring survivability in unheated warehouses and transit containers. Insulating materials meet Class C requirements under DIN VDE 0110, providing high thermal endurance during continuous operation.
