Mains low (under-) voltage (AC side). See also A111. The firing angle is forced to 150° and single firing pulses to suppress the DC current are given.
Check:
− The setting of 31.51.Mains loss mode, 31.52 Mains loss down time, 31.53 Mains loss low level 1 and 31.54 Mains loss low level 2.
− That the mains voltage scaling is correct. See 99.10 Nominal mains voltage.
− The cutting of the voltage coding resistors on the SDCS- PIN-H51.
− The condition of the mains (voltage, cabling, fuses, switchgear).
− That all 3 phases are present directly at the drive.
