18.5. Troubleshooting for
Warning-function Related Errors
18.5.1
Checking the warning display
Indication (A) Main Operating status display
No. Indication Description
A1
Icon shown during normal rotation
operation. Some parameters cannot be
changed while the inverter is running.
A2
Icon shown during reverse rotation
operation. Some parameters cannot be
changed while the inverter is running.
A3
Icon shown during outputting under a
zero-Hz command. It is also shown while
DB, FOC, SON function is working. Some
parameters cannot be changed while the
inverter is running.
A4
Icon shown when an error occurred and
the inverter is in trip state. Releasable
errors can be released by a reset
operation.
18.3.1 Checking trip information
A5
Icon shown when a setting inconsistency
exists.
Eliminate the inconsistency.
18.5.2 Checking setting
inconsistencies
A6
Icon shown while the inverter is forced
stop by the following functions although
operation command is entered.
• An operation command was entered
under 0Hz frequency command.
• Operation command was entered from
a source other than the operation
keypad and the operation was stopped
with STOP key on the operation
keypad.
• The inverter stops by instantaneous
power failure non-stop function.
RUN lamp flashes during this.
A7
Inverter is stopped because no operation
command is given.
The inverter cannot be operated if the stop
terminal functions such as [RS] and [FRS]
or the STO function is ON.
(Notes)
• When A6: STOP (in red) is indicated...
If the value shown in the indication (F): frequency
command is 0.00Hz, the frequency command is 0Hz.
Check whether a frequency command is entered or not.
For example, if the operation was stopped with STOP
key while the inverter had been operated with [FW]
terminal, turn OFF the [FW] terminal and then ON again
to restart the operation.
Indication (B) Warning status display
No. Indication Description
B1
Icon shown while the following functions
are working. [dC-37]
• Under overload limit.
• Under torque limit.
• Under overcurrent suppression.
• Under overvoltage suppression.
• Under upper/lower limit operation.
• Under jump frequency operation.
• Under minimum frequency limit.
B2
Icon shown while the following functions
are working. [dC-38]
• Overload advance notice
• Motor thermal advance notice
• Inverter thermal advance notice
• Motor overheat advance notice
B3
Icon shown during retry standby or restart
standby. [dC-39]
B4
The inverter cannot be operated even
when the operation command is entered.
[dC-40]
• The main power is under insufficient
voltage supply.
• The inverter is operating only with 24V
power supply.
• Under reset operation.
• The inverter is OFF as the [REN]
terminal function is enabled.
B5
Icon shown in fan life advance notice
state.
B6
Icon shown in on-board capacitor life
advance notice state.
B7
Icon shown in fan life advance notice and
on-board capacitor life advance notice
state.
B8
(None)
A state other than those above.
(Notes)
• B1:LIM and B2:ALT are indicated when the current or
internal voltage has increased. If an error is generated,
re-examination of load or other factors is required.
• The above-mentioned indications are shown when the
cooling fan or capacitor on the board is determined to
have reached its product life.
• You can see the detailed warning by pressing UP key
