PARAMETERS
(3) Execution of tuning
1) In the PU operation mode, press on the operation panel. In the Network operation mode, turn ON the start
command via CC-Link communication. Tuning will start.
2) Monitor is displayed on the operation panel during tuning as below.
POINT
Before performing tuning, check the monitor display of the operation panel if the inverter is in the status for tuning.
(Refer to 2) below.) When the start command is turned ON under V/F control, the motor starts.
NOTE
 To end the tuning forcibly, input the MRS signal, command the inverter reset via CC-Link communication, or press
on the operation panel. (Turning the start signal (STF signal or STR signal) OFF also ends tuning.)
 During offline auto tuning, only the following I/O signals are valid: (initial value)
 Input signal MRS, STF, STR
 Output signal RUN, ALM
 Since the RUN signal turns ON when tuning is started, caution is required especially when a sequence which
releases a mechanical brake by the RUN signal has been designed.
 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.
 Do not perform ON/OFF switching of the second function selection signal (RT) during execution of offline auto
tuning. Auto tuning is not executed properly.

REMARKS
 Reference: Offline auto tuning time (when the initial value is set)
 The set frequency monitor displayed during the offline auto tuning is 0Hz.

Offline Auto Tuning Setting Time
Tune all motor constants (Pr. 96 = "1")
Approximately 25 to 75s
(Tuning time differs according to the inverter capacity and motor type.)
Tune motor constants (R1) only (Pr. 96 = "11") Approximately 9s
