I have the “Pololu Jrk 21v3 USB Motor Controller with Feedback (Fully Assembled)” wired up and drivers and Jrk Configuration Utility software installed and can successfully run the Pololu (item #: 1442) motor but with only the “Analog Voltage” feedback option. i read the “Pololu jrk’s Motor Controller User’s Guide” [many times] but there is little information on how to actually setup the “Frequency (digital)” feedback option. [I beilieve i have it wired correctly: Yellow wire from motor encoder (A output) connected to controller’s “FB” input pin; and green wire from motor encoder (“GND”) to “GND” input pin on controller (two pins from FB pin) - is this wiring correct for “Frequency (digital)” feedback option?] Are there examples or other documentation somewhere showing the use of the frequency (digital) feedback option as applied to the motor i am using (item #: 1442), or similar, and associated/typical settings for the “Feedback”, “PID”, and “Motor” tabs in the config utility program? Currently, i have only set the Proportional coeff = 1, other 2 coeffs are = 0. Have other customers been successful with applying the Frequency (Digital) feedback option with this motor and controller combo ? Am i missing something? Help !
thanks for any additional guidance and assistance,
