About the 0-56935-100
The 0-56935-100 is a Current Feedback Printed Circuit Board for the GV3000 AC Drive series. It was originally made by Reliance Electric but was also probably sold by ABB and Baldor Reliance at one point. It has since been discontinued by all of these manufacturers and might have become hard to find. AX Control does attempt to keep the 0-56935-100 in stock as a new surplus or refurbished part.
The 0–56935–100 is specifically a replacement board for a 7.5-10 HP drive on a GV3000 or GV3000/SE series system. The current feedback board is located just behind the regulator card and its bottom CON 2 connection can be seen behind the regulator. The regulator card sends PWM gate signals to the current feedback card which then transmits those signals to drivers that are isolated on the gate driver board.
The 0-56935-100 has two pin connectors labeled CON 1 and CON 2 that are located on the top right and bottom left corners of the card. On the top left corner, there is another connector labeled CON 3. There are a total of 5 resistors, a cylinder aluminum electrolytic capacitor, two large blue capacitors, a ceramic capacitor, a diode, an inductor coil, a Zener diode, two jumpers that are both labeled 7.5 HP and 10 HP. The board is 6.5” long and 2.5” wide. It weighs right around 0.3 lbs.
