Product Description:

The model HCS03.1E-W0070-A-05-NNNV is a robust and efficient drive controller developed by Bosch Rexroth. It is designed for industrial automation applications requiring precision motor control and reliable performance. This device is suitable for use in manufacturing, material handling, and automation systems. It features easy integration into complex systems and provides efficient energy management for continuous operation.

This HCS03.1E-W0070-A-05-NNNV drive controller supports a three-phase mains input voltage range of 400 V to 500 V with a maximum current rating of 70 A. This makes it suitable for medium to heavy-duty applications. The input frequency is 50 - 60 Hz that ensures compatibility with common industrial power supplies. Its rated control voltage input is 24 V and the device has an IP20 protection rating, which means it is protected against small solid objects but is not water-resistant. The model weighing approximately 13 kg. This drive controller also features an internal cooling mode, which helps regulate temperature during operation. The model's short circuit current rating is 42,000 A.

In terms of power factor and efficiency, the HCS03.1E-W0070-A-05-NNNV drive controller achieves a total power factor (TPF) of 0.85 when connected with the mains choke, which drops to 0.57 without it. The power factor of the fundamental component DPF is 0.95 with the choke and 0.64 without it, which indicates its efficient energy management capabilities. The mains input continuous current is 50 A, and the device is capable of handling a maximum inrush current of 2.8 A at its highest input voltage. For power capacity, the connection power is rated at 35 kVA with a mains choke and 22.6 kVA without it. This makes Indramat HCS drive controller a reliable and high-performance option for managing motor control in industrial settings.

Fault / code What it means Corrective action (first-line)
F218 – Amplifier over-temperature Drive heat-sink above shut-down limit Clean/replace blower, improve cabinet airflow, keep ambient ≤ 45 °C 
F219 – Motor over-temperature Stator thermistor tripped Check mechanical load & motor fan path, allow cool-down, verify torque limits
F220 – Bleeder overload Internal brake resistor overheated by regen energy Lengthen decel ramps or add external resistor / regenerative infeed
F226 – DC-bus undervoltage Link < ≈300 V while drive is enabled Find mains sag or blown fuse, verify HCS mains terminals, reset after supply is stable
F228 – Excessive following-error Cmd vs. actual position gap > S-0-0159 Inspect mechanics for jams/slip, reduce accel/velocity, retune position loop
F229 – Encoder-1 quadrant error SinCos / EnDat signals corrupt or missing Reseat X4, inspect shield & 5 V, replace encoder or feedback PCB if required
F230 – Encoder-1 frequency too high Motor speed beyond interface bandwidth Check gearing / max speed; fit high-speed encoder if intentional
F207 – Un-initialised operating mode PLC commanded a mode not parameterised in S-0-0032…35 Enter valid mode or load good parameter set, then Reset Class-1 Diag. ()
F236 – Dual-encoder mismatch Encoder-1 vs. Encoder-2 difference > window Check secondary encoder wiring, realign, repeat commutation
F381 – Mains failure One or more AC phases lost (with HMV/HVR supply) Replace blown fuses, tighten L1-L3 terminals, power-up after all phases OK

Code What it means / likely trigger
F218 Amplifier heatsink over-temperature – internal fan/climate or load too high. 
F219 Motor over-temperature – stator sensor trips under continuous overload or failed cooling.
F220 Bleeder overload shutdown – internal brake-resistor exceeded thermal limit during regen. 
F226 DC-bus undervoltage – mains sag, blown fuse or loose supply terminal while drive enabled.
F228 Excessive deviation – commanded vs. actual position error beyond window S-0-0159.
F229 Encoder-1 failure / quadrant error – corrupted motor-feedback signals or cabling. 
F230 Max. signal frequency of encoder 1 exceeded – motor running faster than interface permits. 
F236 Excessive position-feedback difference – dual encoders disagree beyond tolerance.
F207 Switching to un-initialised operating mode – at least one mode parameter is “0”.
F381 Mains failure (with HVR supply) – one or more AC phases missing.
