First, thank you for buying our drives. Second, don't even think of using a 72VDC power supply with the motor you selected!!!
Your motor specs-out a 1.18 mH winding inductance. The maximum power supply voltage equation is VDC = 32 times square-root mH. That works out to 34.7 VDC (32 * SQRT 1.18 = 34.7).
Your motor temperature will reach 85C or 185F (motor's rated max temperature) with a 35VDC power supply. Your motor will glow red-hot with a 72VDC power supply. Try it at 24VDC and you may find that is plenty and your motor will stay below 70C.
