High Power Service Manual for VLT
Adjustable Frequency Drives
WARNING/ALARM 35, Out of frequency range:
This warning is active if the output frequency has reached the high limit (set in parameter 4-53)
or low limit (set in parameter 4-52). In
Mode
, this warning is displayed.
WARNING/ALARM 36, Mains failure
This warning/alarm is only active if the supply voltage to the adjustable frequency drive is lost
and par. 14-10

ALARM 39, Heatsink sensor
No feedback from the heatsink temperature sensor.
The signal from the IGBT thermal sensor is not available on the power card. The problem could
be on the power card, on the gate drive card, or the ribbon cable between the power card and
gate drive card.
