Every now and then the question comes up as the inductance range the 6410 requires for stepper motor operation.   The answer is none.  The 6410 is not limited to a range of inductances.

The 6410 stepper drive has a patented 4-Phase PWM chopping which electronically controls the motor winding currents at 20 kHz frequency.  The combination of recirculating and non-recirculating current regulation eliminates high back emf with low ripple, which means that the circuit is independent of motor inductance.
