خطای 30002 درایو‌ G120c

راهکار های زیمنس برای این مسئله:

-increase the ramp-down time (p1121).
– set the rounding times (p1130, p1136). This is particularly recommended in U/f operation to relieve the DC link
voltage controller with rapid ramp-down times of the ramp-function generator.
– Activate the DC link voltage controller (p1240, p1280).
– adapt the dynamic response of the DC-link voltage controller (p1243, p1247, p1283, p1287).
– check the line supply voltage and setting in p0210.
– check and correct the phase assignment at the power unit.
– check the line supply phases.

control))
