Multi-function Compact Inverter 3G3MX2-V1 User’s Manual (I585-E1)
The motor or
machine causes a
loud noise.
The carrier frequency is too
low.
Increase the Carrier Frequency (b083) value.
However, this may increase noise or leakage
current from the inverter. In addition, the out-
put current must be derated depending on the
model. For details, refer to
A-1 Derating
on
page A-2.
P. 7-31
P. A-2
The frequency of the motor in
rotation resonates with the
machine's natural frequency.
Change the frequency setting. If resonance
occurs during acceleration/deceleration, use
the frequency jump function settings (A063 to
A068) to avoid the resonance frequency.
P. 7-36
The motor is overexcited.
Set the 1st/2nd Base Frequency (A003/A203)
and the 1st/2nd Motor Rated Voltage Selec-
tion (A082/A282) according to the motor rat-
ings. If this does not improve the condition,
decrease the 1st Output Voltage Gain
(A045/A245) slightly. Or set the 1st/2nd Con-
trol Method (A044/A244) to 02 (Free V/f set-
ting) and perform tuning.
P. 5-9
P. 5-21
P. 7-41
The inverter trips
with an Overload
protection (E05).
The electronic thermal level is
inappropriate.
Set the 1st Electronic Thermal Level
(b012)/1st Electronic Thermal Characteristics
Selection (b013) to a correct value.
P. 5-16
P. 7-73
The inverter trips
with an Overvolt-
age protection
(E07) during decel-
eration.
The set deceleration time is too
short.
Increase the value set in the 1st/2nd Deceler-
ation Time 1/2 (F003/F203/A093/A293).
P. 5-33
P. 5-37
The Overvoltage Suppression
Function Selection During
Deceleration (b130) is set to 00
(Disabled).
Set the Overvoltage Suppression Function
Selection During Deceleration (b130) to 01 or
02 to enable the overvoltage suppression dur-
ing deceleration function. (However, when
this function is enabled, the actual decelera-
tion time may be longer than the set value.
For details, refer to
5-12-1 Overvoltage Sup-
pression Function during Deceleration
on
page 5-63.)
P. 5-63
If an overvoltage trip (E07) occurs during deceleration although Overvoltage
Suppression Function Selection During Deceleration (b130) is set to Enable:
The Overvoltage Suppression
Proportional Gain During
Deceleration (b133)/Overvolt-
age Suppression Integral Time
During Deceleration (b134)
value is inappropriate.
Change the set values. For details, refer to
5-12-1 Overvoltage Suppression Function
during Deceleration
on page 5-63.
P. 5-63
The Overvoltage Suppression
Level During Deceleration
(b131) value is too high.
Decrease the Overvoltage Suppression Level
During Deceleration (b131) value. Note, how-
ever, that setting an excessively small value
may disable deceleration. Consider that the
minimum value is: Incoming voltage
×
√
2
×
110%.
P. 5-63
The inverter trips
with a Thermistor
error (E35).
The Multi-function Input S5
Selection is set to 19 (TH: PTC
thermistor thermal protection)
and 24-VDC voltage is input to
the terminal TH.
Deallocate the external thermistor function
from the terminal TH.
