dampening problems (i think)
dampening problems (i think)
i have an amp3 from lobo and a g120. when i draw a picture (ilda test patern) then, the only thing i see are overshoots. if i adjust the dampening, then nothing happens. is there something broken or just "de tuned" ? if i messure the volt on the pin 8 and 13 ( Oscillator supply voltage) then i have 5 volt but if i messure on the possition feedback output ( of the g120) then i messure nothing. can somebodey please help me. please

Hi,
The Feedback is made by an Oszilator inside the G120. When you put an Osziloscope to the both Pos - Out you mus see something like an Sinus, amplitude depending on the position. At your driver there must be one OpAmp and on his output there is an Position-Depending DC. There also must be an adjustable Resistor for Offset.
The Oszilator inside the G120 needs +12V / <50mA and GND I think, but im not sure.
