Cause/Solution/Troubleshoot
Low speed overload has cleared and can be reset.
Motor overheat sensor reset and Error Motor Overheat
can be reset.
Overload counter has reached 0%, allowing motor to
cool and the error overload error may be reset.
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 connec-
tion.
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 re-
placed or inspected and repaired by KEB.
