Component Test Procedures
Chapter 2
Visual Component Inspection
Visually inspect the circuit boards and power components before energizing
the drive for any of the component test procedures.
1. Read the General Safety Precautions on page
2. Remove power from the drive (see page
3. Remove the protective covers (see page
) and lower the control EMI
) when necessary.
4. Check components for burn marks, breakage or foil delamination on all
circuit boards.
Replace any of these components without further testing if they show evidence
of burn marks, breakage, or foil delamination.
Troubleshoot a Control
Power Supply Failure
If a drive Power Failure fault (F3) has occurred and the drive is inoperable via
the HIM or other means of control, compete the steps below to determine
where the control power failure has occurred.
1. Read the General Safety Precautions on page
2. Remove power from the drive (see page
3. Measure the signal voltage at the testpoints on the control board as
indicated in the following table.
Note: For a flow chart version of the steps that follow, see Control Power
Supply Failure on page
.
4. If any of the signals in the table above is 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 5 below.
• 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 5 below.
