10-lead stepper sanyo, bipolar?

[Peter]

hi!
does someone know if i can run an bipolar stepper (10-lead, always 3
ohms between 2) also in "normal" unipolar mode without polarity-changing?
and if, how?

stepper type:
103-8571-5062
1.25 A
0.72 °/step

a datasheet would also be a great help.

thanks
peter
