More Information

Overview Manuals Axis Selection DC Bus Integration Cable & Cooling Application
  • Match the 20 A maximum-current class to the verified 12.1 A continuous value at 4 kHz
  • Apply the 8.3 A continuous-current limit when the motor is operated with 8 kHz switching
  • Provide a compatible IndraDrive M DC-bus source, separate control section and adequate 27 m³/h cooling airflow

HMS01.1N-W0020-A-07-NNNN is a Bosch Rexroth IndraDrive M HMS01 inverter power section with a 20 A maximum output.

Its 254–750 V DC-bus input supplies a three-phase motor output, with continuous current limited to 12.1 A at 4 kHz and 8.3 A at 8 kHz.

Before replacement, verify the complete type plate, DC-bus source, control section, firmware, motor and brake wiring, cooling path and saved axis parameters.

Availability, condition, price, and shipping time for HMS01.1N-W0020-A-07-NNNN are confirmed during quotation.

Description
HMS01.1N-W0020-A-07-NNNN is a Bosch Rexroth single-axis inverter power section in the IndraDrive M HMS01 family.

Bosch Rexroth HMS01.1N-W0020-A-07-NNNN is an air-cooled IP20 IndraDrive M HMS01 inverter power section for one axis, using a 254–750 V DC bus and delivering three-phase motor output. The complete code identifies the IndraDrive M HMS01 power section, air cooling, current class and A-07-NNNN design. It is not a complete drive controller by itself: the control section, firmware and required system components are separate identities.

Before installation or replacement, confirm the complete HMS01.1N-W0020-A-07-NNNN type plate, separate control section, power and motor connections, cooling arrangement, firmware and commissioned parameters.

Technical notes
HMS01.1N-W0020-A-07-NNNN is an inverter power section, not a complete drive controller; the control section and firmware remain separate. Match the full type plate, DC-bus supply, motor data, cooling and commissioned parameters 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.
Is HMS01.1N-W0020-A-07-NNNN a complete servo drive ready to connect to a motor?
No. It is the power section. A supported control section, firmware and DC-bus supply are separate, and the motor/feedback combination must be engineered for the application.
When should HMS01.1N-W0020-A-07-NNNN be chosen instead of HMS02.1N-W0028-A-07-NNNN?
Choose by the existing IndraDrive M mechanical platform, control-section compatibility, current duty, switching frequency, DC-bus design and cabinet layout. The compact HMS02 is not automatically interchangeable with HMS01.
Why can HMS01.1N-W0020-A-07-NNNN report DC-bus undervoltage while neighboring axes remain healthy?
Check the local DC-bus links, terminal tightness, polarity, connector condition and voltage at this power section during acceleration. A high-resistance joint, damaged bus connection or incorrect group wiring can affect one axis even when the upstream supply and other axes remain operational.
Why can HMS01.1N-W0020-A-07-NNNN fault at low motor speed?
The official data applies reduced continuous current below the standstill threshold. Check load torque, motor tuning, brake release, switching frequency, current limits and cooling rather than assuming the high-speed continuous value.
Why might the motor holding brake fail to release after replacing HMS01.1N-W0020-A-07-NNNN?
The brake command comes through the compatible control section and its configured sequence, not from the power section alone. Verify brake voltage, wiring, relay or output assignment, release delay, motor data, drive-enable state and any active safety interlock.
What cable-space checks apply to HMS01.1N-W0020-A-07-NNNN?
Preserve the documented top and bottom airflow space plus extra room for the motor cable and any HAS02 routing accessory; do not force the cable into the terminal or block the fan path.
How should HMS01.1N-W0020-A-07-NNNN be commissioned?
Verify DC-bus polarity and discharge, 24 V supply, control-section identity, motor and brake wiring, then restore approved parameters and perform rotation, brake, current-limit and low-speed load tests.
