
Motor power (P0307) exceeds invert-
er power capability (r0206).

Motor power (P0307) must match invert-
er power (r0206)
Note : F5 cannot be cleared until the inverter
overload utilization (r0036) is lower than the
inverter I

t warning (P0294).
F6
Chip temperature
rise exceeds criti-
cal levels

Load at start-up is too high

Load step is too high

Ramp-up rate is too fast
Check the following:

Load or load step too high?

Increase ramp-up time (P1120).

Motor power (P0307) must match invert-
er power (r0206).

Use setting P0290 = 0 or 2 for preventing
F6.
F41
Motor data identi-
fication failure
Motor data identification failed.

r0949 = 0: No load applied

r0949 = 1: Current limit level reached
during identification.

r0949 = 2: Identified stator resistance
less than 0.1% or greater than 100%.

r0949 = 30: Current controller at volt-
age limit

r0949 = 40: Inconsistency of identi-
fied dataset, at least one identifica-
tion failed
Percentage values based on the imped-
ance Zb = Vmot,nom / sqrt(3) / Imot,nom
Check the following:

r0949 = 0: is the motor connected to the
inverter?

r0949 = 1 - 49: are the motor data in
P0304 - P0311 correct?

Check what type of motor wiring is re-
quired (star, delta).
F80
AI lost input sig-
nal

Broken wire

Signal out of limits

ALERT CODES
If an alarm is activated the alarm icon shows immediately and then the display shows the alarm code
proceeded by "A". Note that alarms cannot be acknowledged. They are cleared automatically once the
warning has been rectified.

Code Cause Remedy
A501
Current limit

Motor power does not corre-
spond to the inverter power

Motor leads are too long

Earth faults
See F1
Small motors (120 W) under FCC
and light load may cause a high
current Use V/f operation for very small motors
A502
Overvoltage limit
Overvoltage limit is reached. This
warning can occur during ramp
down, if the Vdc controller is disa-
bled (P1240 = 0). If this warning is displayed permanently,
check inverter input voltage.
A503
Undervoltage limit

Main supply failed.

Main supply and consequently
DC link voltage (r0026) below
specified limit.
Check main supply voltage.
A504
Warning level of inverter heat sink
temperature, warning level of chip Note :
r0037 = 0: Heat sink temperature
