Hi to all, my name is Cosimo and I need help about stepper driver.
From an old printer I've get a bipolar stepper and now I'm trying to drive it with L298 and L297 configuration. Whitout the stepper the output of L298 are: 0V 12V 0V 12V. It's ok! But with the motor the output of L298 are: 6V 6V 6V 6V. Why this?
Testing the L297 output I've without the motor: pin 4 0V, pin 6 4.4V, pin 5 4.4V, pin 7 0V, pin 9 4.4V, pin 8 4.4V.
Testing the L297 output I've with the motor: pin 4 0V, pin 6 4.4V, pin 5 2.2V, pin 7 0V, pin 9 4.4V, pin 8 2.2V.

Thanks in advance.

Cosimo
