DVP-ES2 HIGH SPEED COUNTER

[limcm 6]

HI,

I need guidance on HSC, I injected 4khz to X0 the D506 show about 4000hz and D1030 continue increases in numeric.
But when inject 5khz, D506/C243 SHOWN ZERO BUT D1030 continue increases in numeric.

Looking at spec, X0/X2 can read up to 100khz on pulse up.

Also when use Y0 PTO pulse to X0 same as above when 5khz output.

Why the pulse cannot count at 4000hz above? Software or hardware high speed counter same result.

Try out on original Delta dvp-sx2 working perfectly to 100khz.

This dvp-es2 is China built compatible of original Delta dvp-es2.
Thanks for viewing.
