Component Test Procedures
4. Measure the signal voltage at the control circuit board testpoints as
indicated in the following table.
For a flow chart version of the steps that follow, see Control Power
Supply Failure on page
5. If any of the signals in the table in step 4 are incorrect or missing, verify
that either 115V AC or 230V AC voltage is present at terminals U2 and
V2 (control circuit power input).
• If the voltage is present and correct, continue with step
.
• If the voltage is incorrect or missing, remove control power and verify
the wiring and power source to U2, V2, and correct any problems.
Test the voltage level again to verify that it is correct. If the voltage is
correct, but the drive is still inoperable, continue with step
6. Remove AC control power from terminals U2 and V2 and remove and
test the fuse (F1) at the top of the drive. See Switching Power Supply
Fuse Replacement on page
for fuse location.
• If the fuse is open, continue with step
.
• If the fuse is not open, replace the switching power supply board.
7. Replace the fuse on the switching power supply board (see page
).
8. Disconnect the cable at connector XA on the control board. See
9. Apply AC control power to the drive.
• If the fuse opens, continue with Test the Switching Power Supply and
Pulse Transformer Boards on page
• If the fuse does not open, continue with Test the Control and Field
Board Connections on page
