Communication
Error
 Replace the control board
CF01
Operator
Communication
Error 2
 Disconnect the operator and
then reconnect.
 Replace the control board
CT Fault
 Check input voltage signal
and the voltage on the
control board.
Double
Communication
Error
 Check only one
communication mechanism
is used.
PTC Signal
Loss
 Check if MT terminal and
GND terminal are connected.
OPR
Disconnection
 Check if the operator is
disconnected or removed.
FBLSS
PID Feedback
Signal Loss
 Check if the proportion of
loss pressure (23-19) is set
correctly.
 Make sure the feedback
sensor is installed correctly
and PID feedback signal
operates normally.
SC
Short Circuit
 Check if the load is at correct
wiring.
PF
Protection Fault
 Remove run command in
multi-function digital input
terminals.
TOL
External
Overload
 Check external overload.
 Reset external overload of
digital input.
4.3 Warning / Self-diagnosis
Detection Function
When the inverter detects a warning, the
keypad displays a warning code (flash).
Note: The fault contact output does not
energize on a warning and the inverter
continues operation. When the warning is no
longer active the keypad will return to its
original state.
When the inverter detected a programming
error (for example two parameters contradict
each other of are set to an invalid setting),
the keypad displays a self-diagnostics code.
Note: The fault contact output does not
energize on a self-diagnostics error. While a
self-diagnostics code is active the inverter
does not accept a run command until the
programming error is corrected.
Note: When a warning or self- diagnostic
error is active the warning or error code will
flash on the keypad.
Refer to Table 4.2 for and overview, cause
and corrective action for inverter warnings
and self-diagnostic errors.

corrective actions

OV
(flash)
Over voltage
 Increase deceleration time
 Reduce input voltage to
comply with the input
voltage requirements or
install an AC line reactor
to lower the input voltage.
 Remove the power factor
correction capacitor.
 Use dynamic braking unit.
 Replace braking transistor
or resistor.
 Adjust speed search
parameters.
UV
(flash)
under voltage
 Check the input voltage.
 Check input wiring.
 Check power source
 Replace magnetic
contactor
 Replace control board or
complete inverter.
OH1
Heat sink
overheating
 Check the ambient
temperature of the
inverter.
 Check the fan or dust and
dirt in the heat sink.
 Check the carrier
frequency setting.
OH2
(flash)
Inverter over
heating warning
 Multi-function input
function set incorrectly.
 Check wiring
OT
(flash)
over torque
detection
 Check over torque
detection parameters (08-
15 / 08-16).
 Check and reduce motor
load, check and operation
duty cycle.
