Microstep (for 1.8°motor) 6. Power Supply Selection 1,600 The stepper drive PSR8078 can match medium and large stepping motors (from NEMA size 3,200 34 to 42). To achieve good driving performances, it is important to select supply voltage and 6,400 output current properly. -
Page 7: Wiring Notes
ON means standstill current is set to be the same as the selected dynamic current. The standstill current of the stepper drive PSR8078 will automatically be reduced to 50% of the selected dynamic current setting one second after the last pulse. Theoretically, this will reduce motor heating to 25% (due to P=I *R) of the original value. -
