Product Description:

The HCS02.1E-W0028-A-03-NNNN is a drive controller manufactured by Bosch Rexroth Indramat within the HCS IndraDrive Controllers series. It regulates three-phase motors in automated cells, coordinating torque, speed, and position with feedback from the connected motor and encoder system. By combining power electronics and control logic in a single chassis, it simplifies cabinet layouts and supports modular machine designs used in material handling, packaging, and general-purpose motion tasks. This arrangement allows one compact unit to serve as both the power stage and the motion control interface for a machine axis.

The controller employs internal air cooling through an integrated blower, so it can remove heat from the power section without relying on an external fan assembly. Its mains input accepts 3 × AC 200–500 V with a ±10% tolerance, allowing operation on a wide range of plant voltages without a separate transformer. A device peak output of 28 A peak current supplies short-term acceleration energy to synchronous or induction motors during rapid indexing, speed changes, and other transient load conditions. The unit uses design version 1 and has an enclosure rating of IP20 for protected installation inside an electrical cabinet.

Within the HCS02 line, the controller supports applications across a continuous mechanical power range of 1.5–11 kW, which suits small and mid-range axes in coordinated automation systems. The integrated power section supports an infeeding / fed supply arrangement, so regenerative energy from decelerating axes can be returned to the DC bus or dissipated through external resistors when required by the installation.

Fault / code	What it means	First corrective action(s)
F218 – Heatsink over-temperature	Internal heatsink has exceeded the shutdown limit.	Lower continuous load, clean or replace the axial blower, keep cabinet ≤ 45 °C.
F219 – Motor over-temperature	Stator thermistor (or KTY/NTC) in the connected servo has tripped.	Check mechanical load, verify motor-fan airflow, allow cool-down, check torque limits.
F220 – Bleeder overload	Regenerated energy overheated the internal brake resistor.	Soften decel/stop ramps, add an external resistor or upgrade to a regenerative (R-type) supply.
F226 – DC-bus undervoltage	Link voltage dropped below the minimum while the drive was enabled.	Find and correct mains sag, blown fuse or loose terminal; disable drive before removing mains power.
F228 – Excessive deviation	Following-error beyond parameter S-0-0159.	Look for axis jams/slip, reduce acceleration, retune position loop gains.
F229 – Encoder-1 failure (quadrant error)	Motor-encoder signals corrupt or missing.	Reseat feedback plug X4, inspect shield & +5 V, replace encoder or interface if required.
F230 – Encoder-1 signal frequency too high	Motor is spinning faster than the interface bandwidth.	Check gear ratio/command velocities; fit higher-speed encoder if operation is intentional.
F207 – Switch to un-initialised operating mode	PLC requested a mode whose parameter is still “0”.	Enter a valid mode in S-0-0032 … 35 or load a known-good parameter set, then reset the drive.
F236 – Position-feedback difference	Dual encoders disagree beyond monitoring window.	Check secondary encoder wiring/mounting, realign encoders, repeat commutation.
F381 – Mains failure (with HVR supply)	At least one mains phase is missing.	Replace blown fuses, tighten terminals, verify all three phases before restart.
