Control Power Fuse
for models 18kw through 160kW
All Yaskawa GPD 506/P5 and GPD 515/G5 inverters have a control
power fuse. The fuse is located on either the gate drive board (2PCB)
or the power supply board (3PCB). If the fuse is located on the gate
drive board (2PCB), it will be soldered to the board. If the control
power fuse is open, then the gate drive board may be defective. On
the larger inverter models, the fuse is a “plug in” type.
The fuse can easily be checked using an ohmmeter set to the R X 1
scale. Place one lead of the ohmmeter on one side of the fuse, and
place the other lead of the ohmmeter on the other side of the fuse. If
the fuse is bad, the measured value will be infinite ohms.
