3.2.8
Line undervoltage
Fundamentals
Fluctuations in the voltage supply can result in undervoltage. The test reveals whether the drive
switches off when the line synchronization voltage fails.
Test procedure
1. The auxiliary voltage is present.
2. The line synchronization voltage is switched off or reduced down to less than 82 % of the
3. If the line synchronization voltage does not connect again within 2 s or rise above 82 % of
Result
The test is passed if the drive responds as described.
3.2.9
Door limit switches
Fundamentals
Tests are performed in accordance with IEC 61800-5-1
The doors of the drive power section are monitored using limit switches. This monitoring
function ensures that when the doors are open, the drive cannot be switched on.
Test procedure
1. The auxiliary voltage is present. All drive doors are closed.
2. One door of the drive power section is opened.
Result
The test is passed if the appropriate message is displayed on the test station computer.
3.2.10
Overcurrent limit
Fundamentals
The test reveals whether the drive switches off when the overcurrent limit is reached.
