Hbs86 stepper timing

I have a hbs86 stepper driver. I try to figure out the timing. From the manual I get this timing diagram.
 



Am I correct that my values should be ?
Step time 2500ns
Space time 2500ns
Dir Setup 6000ns
Dir hold?
 

I would probably leave some margin since those are minimum timings:

Step time 5000 ns
Space time 5000 ns
Dir Setup 10000 ns
Dir hold  10000 ns

Note that the step time and step space
will limit the maximum step rate so you can reduce
these values if needed, but in general it's better to have
more margin.

The direction setup and hold times have no significant
effect on performance so there's no real reason to
not set them to quite large values for any drive.
