For details, see P.5-6 and 5-7.3) Turn on servo, and start the machine.Estimation of load characteristics starts.4) When the load characteristics are determined, Pr0.04 Inertia ratio is updated.In a specific mode, the following parameters are changed:Pr6.07 Torque command additional valuePr6.08 Positive direction torque compensation valuePr6.09 Negative direction torque compensation value5) When value of Pr0.03 Real-time auto-tuning stiffness setup is increased, the motor re-sponsiveness will be improved.Determine the most appropriate stiffness in relation to the positioning setup time andvibration condition.6) To save the result to memory, write the data to EEPROM.If power is turned off within 30 minutes after the end of tuning process, the result of thereal-time auto-tuning is not saved. If the result is not saved, manually write parameters toEEPROM and then turn off power.2.
