core functionality
8-channel high-speed encoder/pulse acquisition
Support incremental encoder A/B/Z phase, orthogonal decoding, and 4x counting; It can collect flow pulses, speed pulses, and position pulses, and upload real-time count values to the VME bus to the CPU.
Hardware comparison, latch, interrupt
The onboard hardware comparison register generates a hardware interrupt when the set count value is reached; External trigger signal locks the current count value, reducing the computational load on the main CPU.
Channel fault diagnosis
The board comes with hardware self-test, encoder disconnection and signal abnormality detection, panel LED status indication, and fault reporting to the VME system.
Application Scenarios
Steel rolling, papermaking, lifting, collecting encoder position and speed; Cumulative counting of flow meter pulses.
