User Manual of EM730/EM730E Series Inverter If the units place of F04.08 is 2, tracking will be performed from the power frequency. This mode can be applied during switching from the power frequency. If the tens place of F04.08 is 0, search will be performed only in the command direction after speed tracking is enabled. In case that the corresponding speed is not found, the inverter will start running from the zero speed. 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. F04.10 : scanning speed for speed tracking from the predetermined frequency.
The duration is the time for the rated frequency to decrease to 0.00Hz. 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. and the overvoltage protection is enabled, you can try to increase this value. F04.12: tracking intensity, usually taking the default value.
