[Alarm information]
Each message in the table is displayed to give a warning but does not cause the inverter to trip.
Error code
Name
Description
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
.
Deceleration stop function during
power failure activated.
The slowdown stop prohibition function
set with
(momentary power
failure ride-through operation) is
activated.
To restart operation, reset power supply 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).
