karimia Posted March 14, 2018 Share Posted March 14, 2018 Hi, I use a ARTY board to control Motor servoamp. Generates a PWM signal and sends it to the I / O port. When no load is applied, the output voltage swings from 0 to 3.3V. However, when the amp and port are connected, the voltage changes to 1 ~ 2V. Anyone know what the problem is?

zygot Posted March 14, 2018 Share Posted March 14, 2018 @karimia, It's hard to provide an answer with so little information, though I suspect that you can figure this one out on your own. What pins on the Arty-Z7 are you using for the interface? What servo amplifier are you using? Where are you probing? Where is your ground reference point? What IOSTANDARD are you using for the FPGA output pins? What IO current have you set for those output pins? What is the problem (with the servo)?

Hi,
I use a ARTY board to control Motor servoamp.
Generates a PWM signal and sends it to the I / O port.

However, when the amp and port are connected, the voltage changes to 1 ~ 2V.
Anyone know what the problem is?
