BPU-P2

Designed to interface directly with the Delta Tau PMAC2 Motion Controller, the BPU-P2 is a high power brushless PWM servo amplifier in a Eurocard 6U form factor. This unit utilizes state of the art advancements in servo control technology.

The BPU-P2 output power transistors are directly controlled by PWM signals from the PMAC2. The PMAC2 then receives motor phase current feedback from the amplifier digitally via the serial A/D converters. This allows the PMAC2 to close the current loop itself for exceptional servo performance and reduced system cost. An optional backplane accepts connections from the PMAC2 and allows quick and easy hookup of motor, power, control and other I/O signals. This greatly simplifies implementing the BPU-P2 in a motion control system.
