10 ; 54 The ratio between the Encoder 1 pulses[416] and the number of motor pole pairs 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
that is too high.
- 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
that is too high.
- 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 500 VAC.
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 a continuous 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.
