Please clarify the following. If the PS can be as many amps as you want, how is it limited to the motor max, say 2.5A? |
Basically, you set up the xylotex for the current your motor needs through the onboard pot. With the board powered up with the 5V, but NOT the motor power yet, you use a Voltmeter to measure the voltage at the reference pin on the board (actually not a pin, but a small hole) you turn the pot until the voltage is (motor max current x 1.44), for example, a 2A/phase motor would be set to 2.88V. All this is in the data sheet on the Xylotex site. Once this is set, then the Xylotex will only draw this much current from the power supply. Hope this was clear enough.
