I recently purchased a nema 34 stepper motor and a DQ860MA stepper driver to use in a CNC router. I'm looking at purchasing a power supply, but I'm a little confused about the driver specs. The driver says it accepts an input current of less than 6 amps. I was under the impression that you're able to run an amperage higher or equal to as long as the voltage is within the rated range? The power supply I'm considering is 350W 60V 5.8A since this would fit within the driver specs.
My question is, why is the input amperage limited and would the power supply i'm considering work ok with the driver? Thank you very much.
Motor Specs Voltage: 3.6V, Current: 5.6A/phase, Resistance: 0.6 Ohm/phase, Inductance: 6.5 mH/phase
Driver Specs Input Voltage: 24-80VDC, Input current: < 6A, Output current: 2.8A～7.8A
