4.12.3 Execution of offline auto tuning

The following applies to the first motor.
CAUTION
Note the following when "101" (offline auto tuning performed with motor running) is set in Pr. 96 (Pr. 463).
•Ensure safety when the motor starts running.
•Torque is not enough during tuning.
•The motor may be run at nearly its rated frequency (Pr. 84 (Pr. 457) setting) without any problem.
•The brake is open.
•When over current alarm (E.OC1, OC2, OC3) occurs, set acceleration time longer using Pr. 7.
•No external force is applied to rotate the motor.
If "1" (tuning performed without motor running) is set in Pr. 96 (Pr. 463), the motor may run slightly
(However, torque is not enough). Therefore, fix the motor securely with a mechanical brake, or before
tuning, make sure that there will be no problem in safety if the motor runs.
*This instruction must be followed especially in vertical lift applications.
Note that if the motor runs slightly, tuning performance is unaffected.
•During offline auto tuning, only the following I/O signals are valid:
Input signals (STOP, OH, MRS, RT, RES, STF, STR)
Output signals (RUN, OL, IPF, DA1, DA2, A, B, C)
Take extra precaution when designing a sequence where a mechanical brake is opened by the RUN
signal.
