Quick Guide
W A T
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 limit 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 converter.
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 minute.
X X The upper temperature limit has been exceeded.
X X Contact Danfoss.
X Either R value is outside permitted limits, or motor current is too low
S
on at least one phase, or the motor is too small for AMA.
X Inconsistency between registered motor data.
X AMA has detected a missing motor phase.
X Calculations are taking too long, probably caused by noise on motor
cables.
X Warning is given while AMA is performed.
X See parameter 018 Lock for data changes.
