Return to normal operation
When offline auto tuning ends, press the STOP/RESET key of the operation panel during PU op-
eration. For external operation, turn off the start signal (STF signal or STR signal) once. This op-
eration resets the offline auto tuning and the PU's monitor display returns to the normal indica-
tion. (Without this operation, next operation cannot be started.)
If offline auto tuning ended in error (see the table below), motor constants are not set. Perform
an inverter reset and restart tuning.
When tuning is ended forcibly by pressing the STOP/RESET key or turning off the start signal
(STF or STR) during tuning, offline autotuning does not end normally. (The motor constants
have not been set.) Perform an inverter reset and restart tuning.
When using the motor corresponding to the following specifications and conditions, reset Pr. 9
"Electronic thermal O/L relay" as below after tuning is completed.
●
When the rated power specifications of the motor is 200/220V (400/440V) 60Hz, set 1.1
times rated motor current value in Pr. 9.
●
When performing motor protection from overheat using a PTC thermistor or motor with
temperature detector such as Klixon, set "0" (motor overheat protection by the inverter is
invalid) in Pr. 9.
When you know motor excitation current (no load current), set the value in Pr. 82.
Pr. 96 Setting
Error Cause
Remedy
8
Forced end
Set "11" in Pr. 96 and perform tuning again.
9
Inverter protective function operation
Make setting again.
91
Current limit (stall prevention) function was
activated.
Set "1" in Pr. 156.
92
Converter output voltage reached 75% of
rated value.
Check for fluctuation of power supply voltage.
93
– Calculation error
– A motor is not connected.
Check the motor wiring and make setting
again.
Set the rated current of the motor in Pr. 9.
