I use ST L6470 with unipolar motor.
L6470 is biplar type dirver, so I unconnected com line of unipolar motor.
motor spec is below:
 MAKER: sanyo denki
 type : 103H5210-0480
because unconnected com line, resistor is 6.6Ohm.
I apply DC24V in the motor.

The problem  is that motor is not reached 1500PPS.  under 1000PPS, motor is well opeared.

Is it problem thar unipolar motor is used not bipolar?

I changed all variable factor(acc,dec,kval, etc...), but it reached 1500PPS.

what is wrong?
