Product Description:

The HCS01.1E-W0009-A-02-B-ET-EC-NN-L4-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat in the HCS IndraDrive Controllers series. It supervises power conversion and motion control for a single servo axis. The controller links the supervisory PLC to the motor's power stage, so industrial machines can position, index, or tension loads with closed-loop precision. The unit is intended for cabinet-mounted automation systems that require stable axis control during changing load conditions. Typical uses include indexing, synchronized feeding, and position-controlled motion where the drive must respond quickly to command changes.

This unit delivers a peak output of 9 A, giving the axis short-term current headroom during rapid accelerations and brief load changes. System networking is handled by the MultiEthernet port, which supports common industrial Ethernet protocols without add-on cards. Heat is removed by internal air cooling through an integrated blower, helping maintain component temperature inside the enclosure. The power stage accepts 3 × AC 110 to 230 V ±10%, allowing installation on common low-voltage mains. An IP20 enclosure helps prevent accidental contact with live parts after installation in a control cabinet. Integrated functional safety includes STO and SBC, so torque can be shut off and the mechanical brake can be commanded under stop conditions.

Feedback from the motor arrives through the IndraDyn Hiperface/EnDat 2.1/2.2 encoder interface, supporting digital encoder connection for precise position reporting. This feedback path allows the drive to monitor rotor position continuously for stable speed regulation and accurate axis positioning. Motion processing is handled by the control card in the BASIC design type, which supports standard axis functions for general servo tasks. DC-bus energy is exchanged through an infeeding and feeding power supply unit from the same line series, permitting regenerative power sharing between drives on multi-axis machines. This shared bus arrangement can reduce wasted braking energy and helps coordinate power flow when one axis decelerates while another axis accelerates.

Issue Troubleshooting Step
Drive does not power up Verify mains (1×110–230 VAC or 3×200–500 VAC) and 24 V control supply wiring; replace blown fuses or reset the circuit-breaker.
Low DC-bus voltage warning (F2026) Check incoming supply for voltage sag, confirm correct cable gauge, and tighten terminals; reduce simultaneous inrush loads if necessary.
Soft-start fault / DC-bus rise anomaly (F2816) Inspect the soft-start relay, mains contactor, and pre-charge resistor; power-cycle the drive after wiring corrections.
Encoder signal anomalies (F8022 / F2174) Examine motor feedback cable shielding, clean the connector contacts, and verify the encoder type in the parameter list.
+24 V control supply discrepancy (F8070) Measure the control voltage at X31; repair the supply module or wiring if it is outside the 22–28 V DC tolerance.
Interface loss (F4001 / F4002) Check fibre-optic or Ethernet cables, ensure the SERCOS phase has completed, and confirm the device-ID or IP-address settings.
Safety position limit exceeded (F7010) Reset class-1 diagnostics (S-0-0099), review safe-limit parameters, and re-teach the reference position.
Device overload – current limit active (E8057) Clean the cooling fan and cabinet filters, maintain ambient temperature below 40 °C, and consider derating or upsizing the drive.
Torque/force command value limit active (E8260) Reduce acceleration commands, check configured torque limits, and retune the drive control loop if required.
Ground fault indication Perform insulation testing on motor leads, correct any breakdown, and—on IT mains—use an isolating transformer per Rexroth guidelines.
