More Information

Overview Manuals Braking Design Power Integration Control Restore Application
  • Confirm material R911308421 and the complete NNBV power-section identity
  • Size the axis from the documented 95 A continuous output at 4 kHz, not the 150 A maximum alone
  • Match the assigned mains choke, braking resistor, control section and firmware to the original installation

HCS03.1E-W0150-A-05-NNBV, material R911308421, is an IndraDrive C converter for a three-phase 400–500 VAC supply.

At 4 kHz, its documented output is 150 A maximum and 95 A continuous. DC-bus continuous/maximum power is 34/54 kW without the assigned choke and 56/89 kW with the choke.

The NNBV configuration incorporates the control-voltage supply and brake chopper. Verify the separate control section and firmware, HNL01.1E-0240-N0106-A-500-NNNN mains choke, HLR01.1N-0470-N11R7 braking resistor and machine braking cycle before replacement.

Availability, condition, price, and shipping time for HCS03.1E-W0150-A-05-NNBV are confirmed during quotation.

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.
Can HCS03.1E-W0150-A-05-NNBV feed an axis without a separate HMV supply unit?
Yes, when the machine is engineered around the HCS03 converter architecture. This model combines the mains-fed converter role with the motor inverter; verify the 400–500 V grounded supply, assigned mains choke, DC-bus arrangement and braking duty rather than treating it as an HMS inverter that requires a separate supply unit.
When can HCS03.1E-W0150-A-05-NNBV use its integrated 24 V supply instead of an external control-voltage source?
The NNBV design supports the documented integrated 24 V arrangement only under the specified HCS03 conditions, including the applicable control-section configuration and no motor holding-brake load. If the installed control section, safety option or brake requires more control power, size and connect the external 24 V supply specified for the system.
Which braking resistor is assigned to HCS03.1E-W0150-A-05-NNBV?
Bosch Rexroth assigns the HLR01.1N-0470-N11R7 resistor, with 11.7 Ω resistance, to the W0150 size in the technical-data table. Confirm the machine’s regenerative energy and the drive parameter for the external resistor before ordering or wiring it.
Why does HCS03.1E-W0150-A-05-NNBV deliver less current when the switching frequency is raised?
The official table derates both maximum and continuous output current as switching frequency rises. Maximum current falls from 150 A at 4 kHz to 86 A at 16 kHz, while continuous current falls from 95 A to 37 A, so a quieter or higher-frequency setting can invalidate the original torque and thermal margin.
Can HCS03.1E-W0150-A-05-NNBV be connected directly to an IT or corner-grounded delta mains system?
No. The official mains guidance requires a grounded TN-S, TN-C or TT system for direct 400–500 V operation. An IT system or corner-grounded delta arrangement needs the manufacturer-documented isolation or transformer solution before the converter is connected.
Why can HCS03.1E-W0150-A-05-NNBV overheat while the displayed current is below 95 A?
The 95 A value is the 4 kHz continuous output rating, not the standstill limit. At motor standstill the documented continuous current is 60.9 A at 4 kHz and falls further at higher switching frequencies; also check fan airflow, ambient temperature and motor duty.
Which mains choke should be ordered for HCS03.1E-W0150-A-05-NNBV?
The official assignment table lists HNL01.1E-0240-N0106-A-500-NNNN for the W0150 size. Confirm whether the project uses that standard choke or the documented combined filter/choke arrangement, because the DC-bus power figures differ with and without the assigned choke.
