Capture Buffer

The Innovation Series ca pture buffer is used to collect coh erent data at a specified
rate in the drive. The capt ure buffer is circular, and will col lect a fixed number of
samples of each data chann el before overwriting the oldes t data. The capture buffer
can be triggered on any avai lable variable signal in the dri ve by using a Boolean
trigger mode or comparison to a value. The capture buffer will also trigger on a Tr ip
fault. It is u seful for capturi ng drive variabl es for troublesh ooting field pr oblems and
capturing specific dr ive events. The Trend Recorder can display the capture buffer
output.
