Issue:
Perform a Static Test on an Altivar 320
Product Line:
ATV320
Environment:
ATV320 all series
Cause:
Test needed to check for short.
Resolution:
Checking The Input and Output Diode Bridges
This test is done using a digital multi-meter in diode test mode to check that the transistors and diodes are not short-circuited.
ALL TESTS ARE TO BE PERFORMED WITH ALL SOURCES OF POWER REMOVED FROM THE DRIVE
Drive uses all diodes on the Input and Output Diode Bridge.
To confirm the terminals check the ATV320 Installation Manual (link below), from page 97 to 114

ALL TESTS ARE TO BE PERFORMED WITH ALL SOURCES OF POWER REMOVED FROM THE DRIVE
Drive uses all diodes on the Input and Output Diode Bridge.
- Instrument
- Use Digit-Meter with a diode scale
- Measurement
- Locate PA+ and PC- input on drive power terminals (should be close to your power connection terminals)
- Set meter to diode scale
- To measure Input diodes
- Place black on positive bus (PA+) and red on L1
- Get readings and then move to L2, and then L3
- When done swap red and black probes, and measure again between (PA+) to L1...L3
- Readings should be OL in one direction and a low voltage reading the other way (Example 0.3v)
- To measure Output diodes
- Place black on positive bus (PA+) and red on T1
- Get readings and then move to T,2 and then T3
- When done swap red and black probes , and measure again between (PA+) to T1...T3
- Readings should be OL in one direction and a low voltage reading the other way (Example 0.3v)
