Programmable Fault 31.21 Mains phase loss
One or several mains voltage phase(s) are missing. See also 3130. The firing angle is forced to 150° and single firing pulses to suppress the DC current are given.
Check:
− The condition of the mains (voltage, cabling, fuses, switch-gear).
− That all 3 phases are present directly at the drive.
− H1 ... H5: measure the fuses F100 ... F102 on the SDCS-PIN-H01.
− H6 ... H8: check and measure the connections XU1/XU2, XV1/XV2 and XW1/XW2 on the SDCS-PIN- H51.
− For mains supply imbalance.
− For loose mains cable connections.
− That the mains contactor closes and opens.
