Product Description:
The 8I74T401100.010-1 is produced by B&R Automation and belongs to the 8I7 ACOPOS Inverters series. It converts a fixed three-phase mains supply into variable-voltage, variable-frequency output power so production lines can regulate motor speed without mechanical throttling. Designed for cabinet installation, the inverter communicates over the manufacturer’s system bus and supports 10-bit analog command signals. It also integrates an internal brake chopper to meet the dynamic requirements of conveyors, pick-and-place units, and material-handling stations operating at installation altitudes up to 2,000 m.
The drive supports a motor output of up to 11 kW. Its nominal phase current is 27.7 A for continuous operation, while a short-term current rating of 41.6 A for 60 seconds accommodates acceleration peaks before protective derating begins. When supplied by a 500 Vac network, the apparent power reaches 22.2 kVA, providing capacity for demanding motor loads. The standard switching frequency is 4 kHz, and the pulse-width modulation stage regulates the output delivered to the motor. A minimum brake resistance of 16 Ω protects the internal DC link by dissipating regenerated energy during deceleration.
Mains current is limited to 36.6 A at 380 Vac, allowing suitable feeder protection to be selected. The power stage permits a maximum switching frequency of 16 kHz, which can reduce audible motor noise when required. Power losses produce up to 403 W of heat, so the cabinet must provide sufficient airflow and heat dissipation. The housing has an IP20 protection rating and is intended for installation inside a suitable electrical cabinet. It can withstand prospective short-circuit currents up to 22 kA without enclosure rupture. Analog outputs use 10-bit internal resolution for feedback and monitoring tasks.
