I am having a hard time really understanding what all this means. Please correct me if I am completely off here. Torque is proportional to current (amps).Does this mean that although we would be limiting the performance because of the lower volts, the xPRO would provide higher torque/performance than the BB using the same motors? It is my understanding that. The above snippit mentions that you can use up to 4.2a motors on the xPRO and 2.8a on the Blackbox. Was hoping you guys can help shed some light on this for me (and others in my same situation). I have tried to find torque specs for the different nema 23s at 24v but have been unable to. To know if you'll get higher torque out of your stepper motor with the xPRO v5 compared to BlackBox, you need to see how much torque the high torque stepper motor can generate at 24V, which is the maximum recommended power for the xPRO v5. Powering it at 24V is fine but it will limit the torque you get.įor knowing how much torque you can extract out of a stepper motor at each voltage and RPM, you need to refer to the torque vs RPM chart of the motor. High torque NEMA 23 motors such as this 425 oz.in NEMA 23 motor requires 36V of power to deliver the high torque you need at high RPMs. However, even with the xPRO v5, the power that you can supply is limited to 24 volts. Using this thumb rule, you can use a 4.2A stepper motor (NEMA 23 and some NEMA 34 stepper motors) with the xPRO v5.Īnd you can use up to a 2.8A stepper motor with the BlackBox controller such as this highly popular 269 oz.in NEMA 23 stepper motor.
#Siemens step 7 anyway to save one network driver#
The peak current of 6A for the driver implies that the xPRO v5 can run stepper motors with up to a 6A rating (theoretically).īut since you need to extract the full output (torque at high speeds) of the stepper motor, ideally the peak current of the driver should be 1.4 times that of the stepper motor.
