Performing tuning
POINT POINT
• Before performing tuning, check the monitor display of the operation panel or parameter unit if the inverter is in the state
ready for tuning. Turning ON the start command while tuning is unavailable starts the motor.
• In the PU operation mode, press the FWD or REV key on the operation panel.
For External operation, turn ON the start command (STF signal or STR signal). Tuning will start.
NOTE
• Satisfy the required inverter start conditions to start offline auto tuning. For example, stop input of the MRS signal.
• To force tuning to end, use the MRS or RES signal or press the STOP/RESET key 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 terminals <effective signals>: STP (STOP), OH, MRS, RT, RES, STF, STR, S1, and S2
Output terminals: RUN, OL, IPF, FM/CA, AM, A1B1C1, and SO
• When the rotation speed and the output frequency are selected for terminals FM/CA and AM, the progress status of offline
auto tuning is output in fifteen steps from FM/CA and AM.
• Do not perform ON/OFF switching of the Second function selection (RT) signal during offline auto tuning. Auto tuning will not
be performed properly.
• Setting offline auto tuning (Pr.96 Auto tuning setting/status = "1 or 101") will make pre-excitation invalid.
• When the offline auto tuning is selected (Pr.96 Auto tuning setting/status = "101"), the motor rotates. Take caution and
ensure the safety.
• Since the Inverter running (RUN) signal turns ON when tuning is started, pay close attention especially when a sequence
which releases a mechanical brake by the RUN signal has been designed.
• When executing offline auto tuning, input the operation command after switching ON the main circuit power (R/L1, S/L2, T/
L3) of the inverter.
• While Pr.79 Operation mode selection = "7", turn the PU operation external interlock (X12) signal ON to tune in the PU
operation mode.
• During tuning, the monitor is displayed on the operation panel as follows.
