Product Description:

The HDD02.1-W040N-HD is a dual-axis drive controller produced by Bosch Rexroth Indramat within the HDD Drive Controllers series. In multi-axis machining centers and material-handling gantries, this unit supplies regulated current to two servo motors so that position and velocity commands transmitted over a SERCOS fiber-optic ring can be executed without latency. Its primary role in an automation cell is to translate digital motion commands into precisely modulated output currents for torque generation, while internal monitoring handles thermal limits and fault signaling to the higher-level PLC.

This controller has an analog monitor port with a range of DC ±10 V; the port is intended for real-time observation of following error or motor velocity, and it can drive up to 4 mA into a diagnostic meter. For sustained operation at a switching frequency of 4 kHz, each axis can deliver 15 A per axis, while continuous loading at 8 kHz is limited to 10 A per axis; the higher frequency minimizes motor ripple but raises internal dissipation. Short bursts such as acceleration or impact correction are accommodated by a peak envelope of 40 A per axis. When both axes run at their nominal continuous rating, internal conduction and switching elements dissipate 95 W per axis, a value that guides cabinet airflow sizing.

A housing classified at IP10 prevents accidental contact with live parts but requires installation in a closed cabinet. The ready relay can switch loads up to DC 24 V, 1 A, so downstream controllers can detect when the drive is energized; it still responds reliably at 10 mA minimum wetting current. During initialization, the start-lockout circuitry consumes only 1.5 W, reducing UPS load in emergency power schemes. Total unit mass is 8 kg, which supports panel mounting with standard DIN rail or screw hardware.
