More Information

Overview Manuals Frequency Selection Mechanical Integration Protection Checks Application
  • Evaluate the 280 A maximum output separately from the 165 A continuous current at 4 kHz
  • Use the verified 98 A continuous-output limit when configured for 8 kHz switching
  • Check the 200 A mains fuse, mounting position and braking-resistor rating as one protection design

HCS03.1E-W0280-A-05-NNBV is a Bosch Rexroth IndraDrive C HCS03 converter with a 280 A maximum output.

It provides 165 A continuously at 4 kHz and 98 A at 8 kHz from a 400–500 V three-phase mains connection.

Before energizing the replacement, verify mains protection, DC-bus and braking connections, cabinet cooling, mounting orientation, control section and commissioned motor data.

Availability, condition, price, and shipping time for HCS03.1E-W0280-A-05-NNBV are confirmed during quotation.

Description
HCS03.1E-W0280-A-05-NNBV is a Bosch Rexroth IndraDrive C compact converter power section in the IndraDrive C HCS03 family.

Bosch Rexroth HCS03.1E-W0280-A-05-NNBV is an air-cooled IP20 HCS03 feeding compact converter power section for one axis, with a 400–500 V three-phase mains connection, an integrated braking transistor and internal/external 24 V control-power capability. The complete code identifies HCS03 series 03, design 1, feeding supply, internal-air cooling, 280 A maximum-current class, IP20, voltage code 05 and the NNBV option; the control section and any external braking resistor remain separate system items.

Before installation or replacement, confirm the complete HCS03.1E-W0280-A-05-NNBV type plate, separate control section, power and motor connections, cooling arrangement, firmware and commissioned parameters.

Technical notes
HCS03.1E-W0280-A-05-NNBV is the complete NNBV HCS03 power-section code; the control section and external braking resistor are separate. Match the full type plate, mains and DC-bus design, cooling, motor data and firmware before replacement.

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 must be verified before reusing an existing motor cable with HCS03.1E-W0280-A-05-NNBV?
Confirm conductor ampacity, temperature rating, length, insulation, shielding, protective-earth path, connector or lug suitability and routing away from feedback wiring. The cable must also satisfy the documented output and switching requirements of the W0280 power section.
What changes if HCS03.1E-W0280-A-05-NNBV is mounted in position G4?
The official cooling table permits G1 or G4 for the larger group, but the cabinet layout must still preserve the documented airflow, clearances, cable forces and accessibility. Confirm the project drawing before changing orientation.
Can any 200 A fuse be used to protect HCS03.1E-W0280-A-05-NNBV?
No. The fuse must match the Bosch Rexroth-specified type, voltage rating, interrupting capacity and semiconductor-protection characteristics, and it must coordinate with the mains choke, conductors and available short-circuit current.
Why can motor torque fall after HCS03.1E-W0280-A-05-NNBV is changed from 4 kHz to 8 kHz switching?
The permitted continuous output current is lower at 8 kHz, so the converter may reach its thermal or current limit earlier under load. Recheck the motor duty, torque limits, acceleration profile, cabinet cooling and configured switching frequency.
Can HCS03.1E-W0280-A-05-NNBV replace W0350 without changing the cabinet?
The housing envelope is shared, but the current ratings, mains protection, choke and DC-bus power differ. A mechanical fit does not establish electrical or parameter compatibility.
Which system identities must accompany HCS03.1E-W0280-A-05-NNBV in a replacement order?
Provide the complete power-section type plate, control-section type, firmware, motor type, assigned choke and fuse, braking resistor, DC-bus topology and cabinet cooling arrangement.
How should HCS03.1E-W0280-A-05-NNBV be commissioned?
Validate mains and precharge, 24 V control supply, DC-bus sharing, fan operation and configured switching frequency; then perform staged motor, brake and load tests while monitoring current and temperature.
