and Maintenance

The table below lists typical symptoms and the corresponding solution(s).

The motor 

will not run.

The inverter 

outputs [U], [V], 

[W] are not 

supplying 

voltage.

Is the frequency command source 
A001 parameter setting correct?

Is the Run command source A002 
parameter setting correct?

Make sure the parameter 
setting A001 is correct.

Make sure the parameter 
setting A002 is correct.

Is power being supplied to termi-
nals [L1], [L2], and [L3/N]? If so, 
the POWER lamp should be ON.

Check terminals [L1], [L2], 
and [L3/N], then [U/T1],
[V/T2], and [W/T3].

Turn ON the power supply 
or check fuses.

Is there an error code 

E X X

 

displayed?

Press the Func. key and 
determine the error type. 
Eliminate the error cause, 
then clear the error (Reset).

Are the signals to the intelligent 
input terminals correct?

Is the Run Command active?

Is the [FW] terminal (or [RV]) 
connected to [PCS] (via switch, 
etc.)

Verify the terminal functions 
for C001 – C005 are correct.

Turn ON Run Command 
enable.

Supply 24V to [FW] or [RV] 
terminal, if configured.

Has the frequency setting for F001 
been set greater than zero?

Are the control circuit terminals 
[H], [O], and [L] connected to the 
potentiometer?

Set the parameter for F001 
to a safe, non-zero value.

If the potentiometer is the 
frequency setting source, 
verify voltage at [O] > 0V.

Is the RS (reset) function or FRS 
(free-run stop) function ON?

Turn OFF the command(s).

Inverter outputs 
[U], [V], [W] 
are supplying 
voltage.

Is the motor load too heavy?

Reduce load, and test the 
motor independently.

The optional 
remote operator 
is used (SRW).

Are the operational settings 
between the remote operator and 
the inverter unit correct?

Check the operator type 
setting.

The direction of the motor is 

reversed.

Are the connections of output 
terminals [U/T1], [V/T2], and
[W/T3] correct?

Is the phase sequence of the motor 
forward or reverse with respect to 
[U/T1], [V/T2], and [W/T3]?

Make connections according 
to the phase sequence of the 
motor. In general:
FWD = U-V-W, and 
REV=U-W-V.

Are the control terminals [FW] and 
[RV] wired correctly?

Is parameter F004 properly set?

Use terminal [FW] for 
forward, and [RV] for 
reverse.

Set motor direction in F004.
