Recommended operation areas

Relevant for 2 phases ON only. On PWM drivers or chopper (current mode), the current is set to the nominal value and the supply voltage is typically 2.5 to 5x higher than the nominal voltage.

Curves measured with a load inertia of 6·10^-9 kgm², in half-step mode for the “1 x nominal voltage” curve, in 1/4 microstepping mode for the other curves.
