Product Description:

The 8I74S200055.010-1 is an inverter drive from B & R Automation’s 8I7 ACOPOS Inverters series. By rectifying and pulse-width modulating a single-phase mains line, it delivers a variable AC output that lets the system match motor speed and torque to the instantaneous load in packaging, material-handling, and general-purpose automation cells. With a 45 mm width, the inverter conserves panel space when distributed motion axes are added in compact cabinets.

This model is rated for an apparent power of 1.6 kVA, indicating the maximum volt-amp load it can present to the supply without overload. Internal switching operates across a carrier range of 2–16 kHz, allowing adjustment between lower acoustic noise and switching losses. The output section can sweep from 0.1–599 Hz, so both low-speed torque tests and overspeed cleaning cycles can be executed from the same unit. During power-up, the drive draws an inrush of 9.6 A, so input fusing and contactors must be sized for this short-duration surge. Normal operation is fed from a single line rated at 1× 200–240 VAC with the stated tolerance, and an integrated brake chopper and EMC filter are included to dissipate regenerative energy and limit conducted emissions.

The continuous motor circuit is limited to 3.7 A, matching the thermal design of the power stage to typical 0.55 kW machines. That power ceiling of 0.55 kW suits small induction or permanent-magnet motors used for indexing tables or auxiliary pumps. Reliable service is maintained between -10 to 50 °C, and altitude can reach 2000 m before derating rules apply. The housing carries an ingress rating of IP20, so it must be installed in a protected enclosure yet offers straightforward cabinet ventilation. The single-phase supply requirement also simplifies wiring in installations that do not use a POWERLINK network interface.
