Product Description:

The HDC01.1-A040N-DN01-01-FW is a drive controller developed by Bosch Rexroth Indramat for the HDC DuraDrive Controllers series. It governs synchronous or induction motors and exchanges status data through a DeviceNet command interface, enabling coordinated motion in automated cells. The unit regulates acceleration, deceleration, and steady-state speed while managing regenerative energy through an integrated bleeder. This arrangement suits automated lines that keep drive electronics inside a protected cabinet rather than on the machine frame.

The controller delivers a continuous output of 40 A, which is the maximum steady current that the connected motor can draw without thermal overload. Its inverter section supports up to 400 Hz output frequency, so motors with high pole counts or spindle applications can run at elevated speeds. The DC bus can return as much as 0.65 kW of energy at 400 V during deceleration. A continuous bleeder capacity of 0.075 kW dissipates minor regenerative surges during routine stops. For rapid braking events, the bleeder handles peaks of up to 11.5 kW, helping protect bus capacitors and semiconductors. A control charging current of 6.0 A precharges the link through a 60 Ω soft-start resistor, reducing inrush stress on upstream fuses and contactors.

An energy store of 0.585 mF in DC-link capacitance smooths voltage ripple and absorbs short pulses during load changes. The electronics consume only 26 W of auxiliary power, which helps keep cabinet heat low. The unit is fed from a three-phase AC mains network and rejects heat to the environment by natural convection, eliminating forced-air fans. DeviceNet loading remains limited to 35 mA at 24 V, and the built-in 121 Ω termination simplifies bus wiring. Maximum recoverable kinetic energy is 5 kWs, giving tolerance for heavy axial loads, and the 12 kg mass supports stable mounting inside the enclosure.
