Description
HCS01.1E-W0028-A-03-E-S3-EC-NN-L3-NN-FW is a Bosch Rexroth IndraDrive Cs compact converter for one servo axis.

The complete configuration combines the W0028 current class and 200–500 V three-phase mains class with Economy control, S3 Sercos III/EtherCAT, an EC multi-encoder interface and L3 Safe Torque Off. It is one of the HCS01 sizes documented for supplying a DC-bus group when the complete system is engineered accordingly.

Confirm the master protocol, STO circuit, motor and encoder, mains choke and protection, DC-bus duty, braking arrangement, switching frequency and firmware before operation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What does L3 change in HCS01.1E-W0028-A-03-E-S3-EC-NN-L3-NN-FW compared with an L4 version?
L3 provides Safe Torque Off. It does not add the Safe Brake Control function identified by L4. If the machine depends on safety-controlled brake actuation, the safety concept and hardware must be reviewed rather than copying an L4 project.
Can HCS01.1E-W0028-A-03-E-S3-EC-NN-L3-NN-FW supply other drives through a common DC bus?
The W0028 size is documented as suitable for an engineered DC-bus group, but capacity is not determined by the model name alone. Sum simultaneous motoring and regenerative power, select the assigned mains choke and protection, and verify charging and braking limits.
Can the S3 port on HCS01.1E-W0028-A-03-E-S3-EC-NN-L3-NN-FW switch between Sercos III and EtherCAT without modifying the master?
No. The master project, firmware, topology, device description and cyclic communication must match the selected protocol. Changing protocol is an engineering change, not an automatic network function.
Can a B-ET W0028 unit directly replace HCS01.1E-W0028-A-03-E-S3-EC-NN-L3-NN-FW?
No. Although the power size can match, the control-section class and master-communication architecture differ. The controller project, firmware, supported functions and safety validation must be migrated explicitly.
Why can HCS01.1E-W0028-A-03-E-S3-EC-NN-L3-NN-FW trip on overvoltage during deceleration?
Regenerative energy may exceed the available DC-bus absorption or braking-resistor duty. Check the deceleration ramp, moving inertia, DC-bus group state, resistor assignment and parameterization before repeating the stop.
What must be recommissioned after changing an encoder on HCS01.1E-W0028-A-03-E-S3-EC-NN-L3-NN-FW?
Confirm the EC-supported encoder type, cable and supply, then verify motor identity, encoder direction, commutation, position reference and safety-relevant motion behavior before full torque.
What is the practical limit when HCS01.1E-W0028-A-03-E-S3-EC-NN-L3-NN-FW is configured for 16 kHz?
The continuous and maximum output currents are lower than at 4 or 8 kHz. Recalculate the full torque-speed cycle and low-speed thermal load; do not qualify the axis from the W0028 current class alone.
