If you do not set the driver for more amps than the motor is intended for, the only way to overheat the motor is to turn it too fast. Motor heat is a function of POWER. Power is torque times PRM times a constant (depending on units). Current determines the motor torque and Voltage determines how fast you can turn the motor.
So keep the current to the motor spec and moderate your rapid speed, you should be fine.
