Product Description:
The 8BVI0880HCS0.008-1 servo controller is produced by B & R Automation and belongs to the 8BVI Servo Controllers series. As a multi-kilowatt drive module, it regulates three-phase servo motors in automated machinery, supplying torque, velocity, and position control through pulse-width-modulated outputs. Within a motion system, it forms the link between the machine control CPU and the motor windings, processing command data, monitoring feedback, and switching its IGBT bridge so that axes follow programmed profiles accurately during continuous or cyclic production.
At the power stage, the unit can deliver a continuous motor current of 88 Aeff, which supports a continuous mechanical output of 64 kW while drawing 65 kW from the DC link. The internal bus is held at 750 VDC by 1980 µF of capacitance, and a 0.44 µF discharge network accelerates energy bleed-off during shutdown. Maximum output frequency reaches 598 Hz, and the IGBTs switch at 5 kHz to balance acoustic noise with thermal load. For rapid acceleration, the controller supplies a peak of 176 Aeff for short intervals. Timing features include a PWM off delay of 20.5 ms and a trigger rising delay of 52 µs ±0.5 µs, ensuring predictable gating.
Service connections run on a control-logic line rated at 25 VDC ±1.6 %, matching the 24 V supply architecture common to B & R systems. The integrated brake output supplies 4.2 A at 24 VDC (+5.8 % / -0 %) for controlling spring-applied holding brakes. Environmental protection is limited to IP20, so the module is intended for mounting inside a closed electrical cabinet where the ambient does not exceed 55 °C. Under those conditions, the thermal design helps maintain safe junction temperatures during normal operation, and the discharge network supports controlled energy bleed-off during shutdown.
