Maintenance Operations
The motor/machine
is loud.
Carrier frequency is low. Increase the Carrier Frequency (b083).
However, this may increase noise or
leakage current from the Inverter. Also
note that the output current must be
derated depending on the model. For
details, refer to Appendix-1 Derating Table.
5-51
A-1
The motor rotation
frequency and machine's
natural frequency are
resonating.
Change the set frequency. If resonance
occurs during acceleration/deceleration,
avoid the resonance frequency using
Frequency Jump Function (A063 to A068).
5-61
The motor is over-excited. Adjust Base Frequency (A003/A203) and
Motor Incoming Voltage Selection (A082/
A282) to the motor ratings. If the situation
does not improve, slightly lower the setting
of Output Voltage Gain (A045/A245). Or,
set Control Method (A044/A244) to "02:
Free V/f setting" and perform tuning.

An Overload Trip
(E05) occurs.
The electronic thermal
level is not appropriate.
Set Electronic Thermal Level (b012/b013)
correctly.
5-110
An Overvoltage
Trip (E07) occurs
during
deceleration.
The deceleration time is short. Extend the Deceleration Time Setting (F003/
F203/A093/A293).

Overvoltage Suppression
Function During
Deceleration (b130) is set
to "00: Disabled".
Enable Overvoltage Suppression Function
During Deceleration (b130). (Note that
when this function is enabled, the actual
deceleration time may become longer than
the set value). For details, refer to
"Overvoltage Suppression Function During
Deceleration" on page 5-117).
5-117
[An Overvoltage Trip (E07) occurs during deceleration even though
Overvoltage Suppression Function During Deceleration (b130) is
enabled]
The value of Overvoltage
Suppression Proportional
Gain Setting During
Deceleration (b133) or
Overvoltage Suppression
Integral Time Setting (b134)
is not appropriate.
Change each set value. For details, refer to
"Overvoltage Suppression Function During
Deceleration" on page 5-117.
5-117
The value of Overvoltage
Suppression Level During
Deceleration (b131) is
high.
Lower the value of Overvoltage
Suppression Level During Deceleration
(b131). (Note, however, that deceleration
may be disabled if this value is set too low.
As a guide, the set value should be at least
"Incoming voltage × × 110%").
5-117
A Thermistor Error
Trip (E35) occurs.
"19: TH (PTC thermistor
thermal protection)" is
allocated to the multi-
function input terminal S5/
TH and 24 VDC is input.
Cancel the TH allocation.
