help with stepinfo timmings

I have a servo drive (driven with differential signals & step dir) that gives a diagram with timings but i can not understand it
here is the manual at page 17 has the timings
www.vitalsystem.com/portal/cnc/motor_and..._AC_Servo_Driver.pdf
what values must insert in pncconf wizard ?






Can someone help me ?

Is possible to find someone without info from the manufacturer the optimal step on-time / step space / direction hold and direction setup ?
Is there any standard procedure of trial and error to find these timings ?
If i set to high values like 5000ns i have speed drop if i set to low motor does not work.

Your chart you posted has all the info you need
th = Step on time (1000ns)
tl = Step space (1000ns)
ts = Direction setup (1000ns)
Direction hold isn't expressly given, but I would assume 1000ns

If those don't work for you try doubling them, and if you still have trouble, check wiring for noise and voltage problems.

I have tested with 1000ns but losses steps.
1500ns is ok don't loose steps but i can't get speed 3000rpm (i get 1950rpm without errors) is any solution for this ?
Iam thinking electronic gearing or drive them by analog -10v +10v in speed mode with mesa 7i33TA
what is you opinion about analog driving is easy to tune the PID in linuxcnc ?

What mesa hardware do you have now?

What are your steps/rev?

i have mesa 5i24
steps/rev ?

500khz=500000z
T=1/f => 1/500000=2μs period
T=step on + step space
