0047 Auto-tuning error
(PM motor)
When auto-tuning (relating parameters
are pt=6, f400=2), the current of
the permanent magnet motor exceeded
the threshold level.
The inductance of permanent magnet
motor is too small.
Auto tuning for permanent magnet motor
is not allowed for this motor, please
measure inductance with the LCR meter
etc.
[Alarm information] Each message in the table is displayed to give a warning but does not cause the inverter to trip.
Error code Problem Possible causes Remedies
ST (assigned
standby function)
terminal OFF
The ST-CC (or P24) circuit is opened. Close the ST-CC (or P24) circuit.
Undervoltage in main
circuit
The supply voltage between R, S and T is
under voltage.
Internal communication fault.
Measure the main circuit supply voltage.
If the voltage is at a normal level, the inverter
requires repairing for fault.
Retry in process
The inverter is in process of retry.
A momentary stop occurred.
The motor speed is being detected.
The inverter restarts automatically. Be careful
of the machine because it may suddenly
restart.
Frequency point
setting error alarm
The frequency setting signals at points 1
and 2 are set too close to each other.
Set the frequency setting signals at points 1
and 2 apart from each other.
Clear command
acceptable
This message is displayed when pressing
the STOP key while an error code is
displayed.
Press the STOP key again to clear the trip.
Emergency stop
command acceptable
The operation panel is used to stop the
operation in automatic control or remote
control mode.
Press the STOP key for an emergency stop.
To cancel the emergency stop, press any
other key.
/
Setting error alarm /
An error code and
data are displayed
alternately twice
each.
An error is found in a setting when data is
reading or writing.
Check whether the setting is made correctly.
/
Display of first/last
data items
The first and last data item in the
data group is displayed.
Press MODE key to exit the data group.
DC braking
DC braking in process The message goes off in several tens of
seconds if no problem occurs. Note 1)
Flowing out of
excess number of
digits
The number of digits such as frequencies
is more than 4.
(The upper digits have a priority.)
Lower the frequency free unit magnification
.
Momentary power
failure deceleration
stop prohibition
function activated.
The slowdown stop prohibition function
set with (momentary power
failure ride-through operation) is
activated.
To restart operation, reset the inverter or input
an operation signal again.
Auto-stop because of
continuous operation
at the lower-limit
frequency
The automatic stop function selected with
was activated.
This function is cancelled, when frequency
reference reaches LL+0.2Hz or operation
command is OFF.
Parameters in the
process of
initialization
Parameters are being initialized to default
values.
Normal if the message disappears after a
while (several seconds to several tens of
seconds).
Points setting alarm 1
In case of pt=7, there are same setting
value at least two on parameter vl,
f190, f192, f194, f196, or
f198 except 0.0Hz.
Set the points to different values.
Points setting alarm 2
In case of pt=7, the inclination of V/f is
too high.
Set the inclination of V/f to be flat.
Note 1) When the DC braking (DB) function is assigned by using the input terminal function 22 or 23,
it is normal if “” disappears when opening the circuit between the terminal and CC (or P24).
