Product Description:
The 8I76S200037.0P-000 inverter module is manufactured by B & R Automation within the 8I7 ACOPOS Inverters series. Mounted inside a control cabinet, it converts DC bus energy into regulated three-phase output for fractional-kilowatt AC motors used in packaging lines, material handling stations, and similar automated cells. Communication to the machine network is provided through a Powerlink interface of Type 3, and the housing carries an IP20 rating, so the unit is intended for installation in protected electrical enclosures.
It delivers an apparent power of 1 kVA, which is the maximum volt-ampere load the internal inverter stage can supply without derating. Six digital inputs accept position or sensor signals up to a switching frequency of 20 kHz, while three analog inputs with 10-bit resolution support proportional setpoint or feedback processing. The internal control loop samples at a nominal clock frequency of 4 kHz, giving the drive a fast response to command changes. A continuous motor phase current of 3.3 A can be supplied at the output terminals, matching fractional-kilowatt motors commonly used on secondary axes.
During normal operation, the electronics dissipate 38 W of heat, and they draw only 6 W when idle, which helps reduce cabinet cooling demand between cycles. The inverter is intended for motors up to 0.37 kW; during acceleration, it can deliver transient phase current peaks of 5 A and tolerates an inrush of 9.6 A at power-up without tripping upstream breakers. When dynamic stopping is required, the internal brake chopper interfaces with external resistors no smaller than 40 Ω to keep regeneration within safe limits. The two-channel STO circuitry has an input impedance of 1.5 kΩ, allowing direct connection to standard safety relays while maintaining the stated response time.
