W A T Cause of Problem
X X X Voltage or current signal on terminals 53 or 60
is below 50% of preset value.
X X X No phase on mains supply side.
X The intermediate circuit voltage exceeds the lim-
it set.
X The intermediate circuit voltage is lower the limit
set.
X X X The intermediate voltage exceeds the limit set.
X X X The intermediate voltage is lower than the limit
set.
X X The frequency converter is close to tripping due
to overload.
X X The motor is too hot due to overload.
X X Either the motor is too hot or the thermistor has
been disconnected.
X X Output current is higher than set in par. 221.
X X X The peak current limit has been exceeded.
X X Discharge from output phases to earth.
X X Fault in switch mode power supply.
X X Short-circuit on the motor terminals or in the
motor.
X X No serial communication to the frequency con-
verter.
X X No serial communication to the communication
option card.
X Output frequency has reached the limit set in
either par. 201 or par. 202.
X X Fault only occurs in fieldbus versions. Please see
par. 953 in fieldbus literature.
X X Connected to mains too many times within 1 mi-
nute.
X X The upper temperature limit has been exceeded.
X X Please contact Danfoss.
