Hello,
I need help choosing power supply and If you could explain to me why the manufactured recommended for me power supply with output 80vdc and 12A !! Why 12A ? As I understand from searching on the web it should be
Current*=*Amps*needed*per drive***Number*of*drives *0.7
I have :
4x LAM Technologies 2 phase stepper motors ( 7.1 Arms, 1.85 V, 0.26 Ohm, 2.2 mH (each phase))

4x LAM DS1078 driver rated 4.0-10.0A (RMS) respectively 5.6-14.1A (peak) each phase.
The manufacture suggest me to use a power supply with 80Vdc output voltage and 12A output current. Is 12A enough for the 4 axis?
Appreciate your help
