LED display Description
Cause Possible solutions
Operator
Writing Error
Operator cannot write the
information into the inverter.
 Data control mode in
operator is not consistent
with that in the inverter.
 Data models in operator
are not consistent with that
in the inverter.
 Data firmware version in
operator is not consistent
with that in the inverter.
 Check the inverter’s
firmware version/ control
mode/ models
WRE*
Operator
Verifying Error
After operator reads or writes
data in the inverter, user can
verify it. If the data are not
consistent, the inverter
displays the signal of verifying
error.
 The data in the operator
and the inverter is not
consistent.
 Check if the inverter is
normally connected to
the operator.
VRYE*
Repeat Run
Command
The inverter is only allowed
unidirectional operation and
cannot operate in reverse
direction simultaneously.
 Check if the external
terminal is given a run
command in reverse
direction.
 Cancel the run command
in reverse direction from
the external terminal.
Operator Read
Prohibit
Selection of allowing reading
(16-08) is set to 0 (Do not
allow to read inverter
parameters and save it to the
operator).
 Set parameter 16-08 to 0.
 Set parameter 16-08 to 1
(Allow to read inverter
parameters and save it to
the operator).
RDP*
External
Emergency
Stop
Function of external
emergency stop starts.
 Parameter 03-00~03-08 is
set to 14 (Function of
emergency stop is
enabled.)
 Remove & shutdown the
run command of external
emergency stop and
reset it to multi-function
digital input.
Zero Speed
Stop Warning
The operation signal is
enabled but frequency
command is lower than the
minimum output frequency
(01-08) and DC brake is
disabled.
 The frequency command
is not set up.
 Set up the frequency
command.
Overload of Air
Compressor
If the inverter’s output current
reaches OL4 current level
(23-69), OL4 Delay Time
(23-70) passed. When the
count is reached, the inverter
will automatically decelerate
to stop and displays a warning
signal.
 Since the current level (23-
69) is set to be over low,
the inverter’s output
current is higher than the
standard one or
compressor’s current is
used to be over high.
 Check if the compressor
load used is higher than
the standard one.
PID feedback
signal loss
When 23-19 > 0, the inverter
will according to feedback
pressure is less than
(pressure transmitter
maximum pressure (23-03) x
proportion of loss pressure
detection (23-19)) value, if the
pressure loss detection time
(23-18) passed and 23-78 = 1
(loss of pressure detection
function) will jump warning
si
g
nal
 23-19 proportion of loss
pressure detection is too
big
 Feedback sensor install
failure or not work normal.。
 Check 23-19 setting.
 Make sure correct
installation and PID
feedback signal.
* RDE、WRE、VRYE、RDP warning signals are only displayed in LCD keypad.
