PWM measurement with PCI 6602

[sa428]

Hello ,

I am new to PCI 6602 . Can someone please explain me the connections to be made to the gate and source to be made.

I am RC servo so the PWM signal should go to the source , then what should i provide to the Gate.

Any help would be appreciated. 

Thanks in advance.

 Hi Sweety,

What type of measurement do you want to make with the servo motor (edge count, frequency, pulse width, etc.)?  What wires are output from the servo motor?  Depending on the answers to these questions it will give more information into whether you need to use the gate terminal or just the source. 

I would recommend to review the User manual for the PCI-6602 (referenced below) because it has information on the pinouts (pg 31) and different application considerations.  Also, the M series user manual discusses some of the different measurements (in the counter section) and how to make the proper connections.
