It's not because your drive can provide some power rating that it is the best choice for the motor.

You need to ensure that you are not driving the motor winding into magnetic saturation for a sustained period at low revs or on on hold. Look at the current rating of the motor and the static coil resistance. Over stepping the current rating will just heat up the iron core in the motor without producing an ounce more effort. They will stand it for a short time but it is doing nothing but heating the motor.

The coil windings should be able to stand the rated current indefinitely and hopefully the motor will have been designed to produce max. magnetic field ( ie magnetic saturation ) at that current.

don't stick 80V across a 1 ohm coil rated at 3A , just because you can !
