Product Description:

The HDS02.2-W040N-HT20-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for axis control tasks in automated machinery. It belongs to the HDS Drive Controllers series and functions as the power and regulation stage between a DIAX04 master and the connected servo motors. Within an automation cell, the unit converts incoming DC bus energy into precisely metered phase currents, enabling coordinated speed, torque, and position loops for packaging lines, handling gantries, and similar motion applications.

The controller communicates with higher-level motion CPUs through SERCOS, allowing synchronous setpoint updates and real-time diagnostic feedback across a single fiber-optic ring. Its output stage is rated at 40 A, providing continuous current for medium-power Indramat servo motors while still permitting short overload peaks during acceleration. Thermal management is handled by a built-in air blower, and the integrated fan pulls cabinet air across the heat sink so external ductwork is unnecessary. Windings and power devices are insulated to Class C per DIN VDE 0110, permitting higher junction temperatures before dielectric stress becomes critical. For steady operation, the electronics must remain within an ambient range of +5 to +45 °C, which helps maintain specified current linearity.

The housing is specified for use up to 1000 m above sea level, ensuring adequate air density for the internal blower at typical factory elevations. If panel temperature exceeds the standard band, the unit can still operate with reduced current until cabinet air reaches +55 °C. During storage or shipment, the electronics tolerate a wider span of -30 to +85 °C, which helps protect components during seasonal temperature changes. The enclosure has an IP10 rating according to DIN 40 050, which blocks accidental finger contact with live parts while relying on the control cabinet for broader dust or fluid protection.
