Troubleshooting Tips
The table below lists typical symptoms and the corresponding solution(s).
1. Inverter does not power up.
Possible Cause(s)
Corrective Action
Power cable is incorrectly wired.
Check input wiring
Short bar or DCL between [P] and [PD]
is disconnected.
Install short bar or DCL between [P] and [PD] terminal.
Power cable is breaking.
Check input wiring.
2. Motor does not start.
Possible Cause(s)
Corrective Action
Incorrect RUN command source is
selected.
Check RUN command source (A002) for correct source.
Ex. Terminal (digital input) : 01
Operator (RUN key) : 02
Incorrect frequency source is selected.
Check frequency source (A001) for correct source.
Ex. Terminal (analog input) : 01
Operator (F001) : 02
Frequency setting is 0Hz.
If frequency source is terminal (A001=01), check analog
voltage or current signal at [O] or [OI] terminals.
If frequency source is operator (A001=02), set frequency in
F001.
Depending on frequency source, input proper frequency
reference.
If frequency source is multi-speed operation, set frequency
in A020 to A035 and A220.
RUN command is not set to input
terminal.
If RUN command source is terminal (A002=01), set
"forward" (00:FW) or "reverse" (01:RV) to any input
terminals. In case of 3-wire control, set "3-wire start"
(20:STA), "3-wire stop" (21:STP) and "3-wire FW/RV"
(22:F/R) to any input terminals.
“Multi-speed input(s) (02 to 05:CF1 to
CF4)” is (are) set to input terminal(s)
and active.
Deactivate the input(s).
Both FWD and REV input are active.
If RUN command source is FWD/REV input, activate
either FWD or REV input.
Rotation direction restriction (b035) is
enabled.
Check b035.
Incorrect input wiring or short bar
position
Wire inputs correctly and/or install short bar. (ON/OFF
status of inputs are monitored in d005.)
Incorrect analog input or variable
resistor wiring
Wire correctly.
In case of analog voltage or variable resistor input, check
voltage between [O] and [L] terminal.
In case of analog current, check current between current
source and [OI] terminal.
RUN command source is operator, but
input terminal is set to "Force terminal"
and active.
Deactivate the input.
RUN command source is terminal, but
input terminal is set to "Force operator"
and active.
Deactivate the input.
Inverter is in trip status.
(With ALARM LED and "Exxx"
indication)
Reset inverter by STOP/RESET key and check error code.
