Figure5.4.1.5 Auto tune center – auto tuning
After clicking the “Execute” button, the drive will drive the motor to vibrate at different frequencies
and the status light of “Auto tuned” will continue to flash. After the firing single is sent completely, the
drive will disable the motor and perform the gain tuning algorithm. When the light stops flashing and
the progress bar is full, it means that the process of auto gain tuning is finished (the execution time is
about 25 seconds). After that, if the light keeps green, it indicates that the auto gain tuning is
successful; while if the light keeps red, it indicates that the auto gain tuning is failed. The failed case
and troubleshooting refer to Section 5.4.3. If the auto gain tuning is failed, the gain tuning and filter
design will recover to the original setting.
5.4.2 Announcements
If the mechanical system meets following conditions, the auto gain tuning easily fails:
(1) The stroke is not sufficient (for example, the motor running range is less than one revolution).
(2) The weight or inertial of load changes too much during the tuning process.
(3) The mechanical system touches the hard stop at tuning.
(4) The dynamic friction of mechanical system is too large.
