Product Description:

The HDS03.1-W075N-HS59-01-FW is an axis drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed within DIAX04 modular drive cabinets, it supplies regulated power and closed-loop control to servo motors used in tooling machines, printing lines, and factory conveyors. By combining control electronics and power conversion in one housing, the unit simplifies cabinet layouts and lets machine systems coordinate multi-axis motion over fiber-optic command links. In typical automation systems, it serves as the power stage between the DC bus and the motor while the control section manages torque during acceleration, steady running, and braking.

This controller exchanges real-time setpoints through a SERCOS interface, enabling synchronized positioning with neighboring drives on the ring. A continuous output capability of 75 A supports medium-to-high torque servo axes without external boosters. Thermal energy is removed by a built-in air blower, which forces cooling air across the heat sink and helps the power section maintain stable thermal behavior during continuous duty. The housing is rated IP 10 per DIN 40 050, giving basic finger protection for indoor switchgear cells. Reliable operation is specified within an ambient range of +5 to +45 °C; outside this range, temperature-related derating or cabinet conditioning is necessary to maintain current limits.

An installation altitude of up to 1000 m above sea level is allowed before further derating tables apply, which suits many industrial sites. For short-term peaks, the electronics can withstand cabinet air reaching +55 °C when the output current is reduced according to the manufacturer’s chart. During non-operational periods, components tolerate a storage or transport window of -30 to +85 °C, which helps protect the unit during shipment and warehouse storage. These operating limits are important in enclosed cabinets where internal heat can rise above room temperature during sustained multi-axis operation. Windings and insulation materials fall under class C per DIN VDE 0110, allowing higher internal temperatures during demanding motion profiles.
