Name
Description
Possible Causes & Corrective Action
Undervolt Flt
[F47]
This fault is generated during a run
condition if the DC bus voltage falls
below the level that is specified by UV
Fault Level (A4).
Fault is declared when:

Low Input Voltage
Check INPUT L-L VOLTS (A4) and UV
FAULT LEVEL (A4) parameters
Disconnect Dynamic Braking resistor
and re-try.
Verify proper input voltage and increase,
if necessary, the input AC voltage within
the proper range
Check for a missing input phase
Check power line disturbances due to
starting of other equipment
Drive Accurately Reading the Dc Bus
Measure the dc bus with a meter across
terminals B1 and
–
Compare that with the value on the
digital operator, DC BUS VOLTAGE
(D2)
Hardware Problem
The drive may need to be replaced.
Uv Alarm
(alarm)

This alarm is generated during a run
condition if the DC bus voltage falls
