5.4 Fault Indications
In the event of a fault condition arising, the inverter will stop and the display will indicate F, followed by a two–digit
code (see Figure 5 below) .
Fault Code Cause Corrective Action
Excessive load current Ensure rating plate on motor corresponds with
inverter rating
A low frequency voltage boost may be required
to start the motor
The characteristic voltage/frequency curve of
the inverter may not match that required by the
motor
The acceleration time for the motor may be too
short
Excessive link voltage Ensure line voltage is within the limits specified on
the inverter rating plate.
The deceleration time of the motor may be too
short
Low line voltage
(Models 6SE210*–3AA01 only)
Check that the voltage of all three input power
phases is within the limits specified on the inverter
rating plate.
Excessive heatsink temperature Check that the unit has been installed with at least
100 mm clear space above it for exhaust air and
that the air inlet at the bottom of the unit is not
obstructed.
Check that the ambient air temperature is below
Check that the steady motor current is not above
the limit specified on the rating plate.
Corruption of parameterisation
data in the non–volatile memory
Reset all parameters
Faulty operation of the
analogue–to–digital converter
Check that the analogue input voltage on terminal
X11.7 is less than +12 V and greater than –0.5 V.
If operating in current loop control, check that the
current entering control terminal X11.9 is less than
25 mA and greater than –1 mA.
or
or
The minimum frequency parameter Reset parameter P07 or P08.
(P07) has been set to a higher
value than the maximum frequency
parameter (P08).
The fixed frequency parameter Reset parameters P07, P08 or P09.
(P09) has been set outside the
minimum/maximum frequency
limits set by parameters P07 &
P08. Note that this fault indicator
will only be enabled if P04 is set
to 003.
Check whether the motor is stalled or overloaded.
Check for short–circuits or ground faults on the
output leads.

inverter, pressing all three parameterisation buttons
simultaneously while applying power to the inverter.
The display will indicate ‘CAL’ for several seconds
while it recalibrates the monitor circuit.
