The application of Delta VE series inverter in CNC machining center (3)

Run using the panel. First, F=550, after running, it is found that regardless of the starting process or the stopping process, when the output frequency reaches about 450HZ, it does not change according to the acceleration/deceleration time, and the change is very slow. When the above phenomenon occurs, it can be solved by adjusting parameter 11-05 (M1IdsRef Limit). After 11-05 is changed from factory value 90 to 110, the acceleration/deceleration process is normal.
Figure 2 (F = 590, 11-05 = 180) acceleration curve
(4) Inertia estimation and ASR automatic adjustment. The parameters 11-00=2, F=200HZ, 01-12=01-13=1, the inertia parameter measured after positive and negative reversal is 49, then 11-01=1, observe the rigidity of the motor, and make the corresponding parameters modify.
(5) Setting of external I/O function:
Referring to Figure 1, MI1 is a single point positioning, MI2 is the first/second acceleration/deceleration time switching, and MI3 is the pulse position command input enabling single point positioning. FWD/MI1 is closed and the inverter performs positioning operation. The following parameters are related to the sensitivity of the positioning and the stop position during positioning. When adjusting the position, the spindle can be stopped at the position to be positioned and the G state value on the panel is observed. After determining the position is correct, the observed G value is filled in. 10-19; the sensitivity of the positioning process is changed by adjusting 10-21/10-22, the larger the 10-21, the smaller the 10-22, the faster the reflection, the shorter the positioning process; the smaller the 10-21, 10 The larger the -22, the slower the reflection and the longer the positioning process.
