The motor does not run.
Is the 7-segment LED
extinguished?
Is  displayed?
Is any failure message
displayed?
(Refer to section 13.1)
Are  and a failure
message displayed alternately?
Is the LED of the RUN/STOP
key lighted?

key off?
 displayed?
Determine the cause, using the parameter display function and the status monitoring function.
Refer to chapter 11 for the parameter display function or chapter 8 for the status motoring function.
YES:
NO :
Check the power supply and the MCCB.
Is power being supplied normally?
Check the terminal P0 and PA/+.
Is the shorting-bar being connected ?
 The ST-CC circuit is opened. Close the circuit between CC and the terminal to which
the ST (standby) function on the control circuit terminal is assigned.
 The FRR and CC circuit is closed. Open across CC and the terminal that is assigned
the FRR (coast) on the control terminal block.
 Check the always active functions selection parameter () setting. (Refer to
section 6.3.2)
Track down and eliminate the cause of the failure and then reset the inverter.
Refer to section 13.2 for the way to reset.
The inverter is in the process of retrying. The retry function can be disabled by normal or

(Refer to section 3.2.2)
 Check the settings of frequency setting signal points 1 and 2. (Refer to section 6.5.2)
 Check the operation start frequency setting to see if it is larger than the operation
frequency. (Refer to section 6.6.2)
