Selection and protection of a motor
(3) Execution of tuning
POINT
Before performing tuning, check the monitor display of the operation panel if the inverter is in the status for tuning.
(Refer to 3) below.) When the start command is turned ON under V/F control, the motor starts.
1) Set "1" in the X12 signal (Bit11), which gives a control input command through FL remote communication. Then,
change the operation mode to the PU operation mode using
2) Press on the operation panel. Tuning starts.
(When the Network operation mode is selected and "1" is set in the X12 signal (Bit 11), which gives a control input
command through FL remote communication, the inverter output is shutoff. Therefore, inputting a start signal through
FL remote communication does not start tuning in this condition.)
NOTE
To force tuning to end, press
X12 signal is the only valid input/output signal during the offline auto tuning.
Setting "0" in the X12 signal while tuning is being set or performed forces the operation mode to change to Network
operation mode.
Use the X12 signal after setting "0" (stop command) in the forward/reverse rotation command (STF/STR signal) to set
and perform tuning.
When executing offline auto tuning, input the run command after switching on the main circuit power (R/L1, S/L2, T/
L3) of the inverter.
3) Monitor is displayed on the operation panel during tuning as below.
