(13)
Control card is
powered up,
but the power
stage is not, so
consequently it
is not seen by
control card.
The Power Unit Not Ready message may occur due to
the following conditions:
Control card powered up by external power supply, but
drive is not powered up by line. Since the drive is not
being powered by the line, the power stage cannot be
identified.
Connection issue between control card and power
stage.
For inverter housing sizes G, H, R, U, remove
then reconnect the ribbon cable connecting the
control card to the power stage at the control card
connection.
For inverter housing sizes D, E, remove the control
card then re-seat, ensuring pin connections.
Switching power supply.
If reseating the ribbon cable does not resolve the
issue, then there may be a failure of the switching
power supply and the drive would need to be
replaced or inspected and repaired by KEB.
