User Manual of EM730 Series Inverter If the tens place of F04.08 is 1, search will be performed first in the command direction after speed tracking is enabled and then in the opposite direction if no speed is found. is the time for the rated frequency to decrease to 0.00Hz. F04.10 : scanning speed for speed tracking from the predetermined frequency. The duration F04.11 : current tracking, ratio to the rated current of the inverter. The lower the current, the less the impact on the motor is, and the higher the tracking accuracy is. If the set value is too small, the tracking result may be inaccurate, causing failure in start. The higher the current, the less the motor speed drops.
This value should be increased during heavy-load tracking. F04.12 : tracking intensity, usually taking the default value. When the tracking speed is high and the overvoltage protection is enabled, you can try to increase this value.
