CODE CAUSES
10 ; 54 The ratio between the Encoder 1 pulses[416] and the number of motor poles pair must be
higher than 128
3 ; 4 The Stator resistance [436] value is too high. The motor is not compatible with the drive
size used.
5 ; 8 ; 9 ; 15 The Leakage inductance [437] value is too high. The motor is not compatible with the
drive size used.
16 ; 24 The Rotor resistance [166] value is too high. The motor is not compatible with the drive
size used.
17 The Nominal voltage [161] and Nom frequency [163] values produce motor nominal flux
(out of range) that is too high.
- Verify these values: the Nominal voltage value is too high and/or the Nom Frequency
value is too small.
18 The Base voltage [167] and Base frequency [168] values produce motor nominal flux (out of
range) that is too high.
- Verify these values: the Base voltage value is too high and/or the Base frequency value
is too small
23 The ratio between nominal flux (Nominal voltage, Nom frequency) and working flux (Base
voltage , base frequency) is too high.
- Verify the above parameters value.
The Magnetizing current [165] value is too high.
- Verify that this value is lower than Full load curr.
27 The Base voltage value is too high. The maximum value is 500V.
28 The Base frequency value is too high. This value must be lower than 500Hz
59 The Magnetizing working curr [726] is too high.
- Verify that the nominal flux value (Nominal voltage and Nom frequency) is lower than
the working flux value (Base voltage and Base frequency). Check the parameters value.
The Magnetizing current value is too high.
- Verify that this value is lower than Full load curr.
64 The Motor cont curr [656] value, of the motor thermal protection function (menu Ovld
mot contr), produces continuative current that is too low in comparison to the used inverter
size. This error can also be due to a too low setting of the Nominal current [164] parameter
(0.3 x I
2N
).
66 The Nominal speed [162] value is wrong.
The set value produces too small (or too high) slip value.
