I installed a Mesa 5i25 with 7i77 to drive a Minibravo 60 Brushed DC motor drive. It drives a Brushed DC motor (ESA 3M 8019) from Motor Power Company. There is a encoder fitted to the motor. Also an ESA 3Mxx? There is a 10:1 planetary gearbox fitted to the shaft.
The Minibravo's are designed to work with a tacho and has a tunable PID interface when using the tacho. These drives are fitted with an encoder interface board that turns the pulses into an analog voltage that is supposed to be representative of the rpm of the motor. When the encoder option is used it seems that the PID is not in circuit. The problem is that I get a constant severe oscillation when the motor is in rest as well as when it is driven. When I scope it with Halscope, I see the constant ripple on the feedback count as well. If I remove the analog input signal to the drive, I still get the oscillation. Has anyone have any experience with this kind of setup. Your assistance will be appreciated :) -- Regards /Groete Marius D.
