It is, it just needs up and down pulse trains on two inputs instead of the usual step/dir.
In the hal file you will have this
setp hm2_7i76e.0.stepgen.00.step_type 0
Change that to this, for the axis that that drive is wired to
setp hm2_7i76e.0.stepgen.00.step_type 1
Notice that the stpgen number might be 01 or 02 for that axis, like
setp hm2_7i76e.0.stepgen.01.step_type 1
or
setp hm2_7i76e.0.stepgen.02.step_type 1

No.Do you mean that the driver is not capable for position control?

You can get away with 3 but it is better with 4 as it is more immune to interference.So i go to the hal file for that

Change these to 5000
DIRSETUP = 1000
DIRHOLD = 1000
STEPLEN = 1000
STEPSPACE = 1000
Also have you connected the enable on the drive if so disconnect it to test
