- 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.
