Indicates
Bus voltage has exceeded 130% of
the rated DC bus voltage —
— 537VDC for a 380VAC input.
— 650VDC for a 460VAC input.
Current has exceeded 198% of the
rated converter current.
Bus voltage has exceeded that set
by P16 - [BOV SW Trip].
1336 REGEN Converter input
current has exceeded that set by
P14 - [IOC SW Trip].
A phase locked loop error has
exceeded the software trip point set
by P22 - [PLLReg Err Trip]. This
can occur for several reasons.
1. The utility voltage is corrupted or
unbalanced.
2. One of the line voltage feedback
inputs is missing.
Current has exceeded 150% of
rated line current for (1) minute or
the equivalent IT value (current ×
time).
Action
1. Reduce the braking current limit
of the connected AC drive.
2. Reduce regeneration demand
on the connected AC drive by
reducing braking time.
3. Reset and re-enable the
Converter.
1. Reduce the current limit of the
connected AC drive.
2. Check AC line fuses.
3. Reset and re-enable the
Converter.
4. If problem persists, replace the
Converter Control Board. If
problem reoccurs, check
Converter IGBT devices.
1. Check the DC bus overvoltage
trip level set in P16.
2. Reduce regeneration demand
on the drive by reducing braking
time.
3. Ensure that the 1336 REGEN
Package is correctly sized for
the application.
1. Check the instantaneous
overcurrent trip level set by P14.
2. Reduce the Converter's current
limits.
3. Ensure that the 1336 REGEN
Package is correctly sized for
the application.
1. Ensure that P22 - [PLLReg Err
Trip] is set correctly.
2. Verify that the utility's voltage is
within the specifications listed in
Appendix B.
3. Check voltage feedback inputs
at the 1336 REGEN Precharge
Unit's input contactor.
Reduce Converter loading.
