Introduction
The ET-7083 is a 3-axis high speed encoder/counter module. Each axis can be individually configured for Quadrant, Pulse/Direction, or CW/CCW counting modes. The maximum input rate for Quadrant counting mode is 1 MHz, and for Pulse/Direction, CW/CCW counting modes is 4 MHz. The encoder/counter module is equipped with a FRAM to retain the counter value after it is powered off. FRAM is a nonvolatile memory that can hold written data even after it is powered off. The data retention can be 10 years. And the feature can be configured as enabled or disabled.
