ABB DC OVERVOLT fault code meaning
ABB / DC OVERVOLT
Series: ACS600
DC overvoltage
drive
Meaning: Intermediate circuit DC voltage is excessive. DC Ch overvoltage trip limit is 1.3 · U1max, where U1max is the maximum value of the mains voltage range. Ch For 400 V units, U1max is 415 V. For 500 V units, C U1max is 500 V. The actual voltage in the intermediate circuit corresponding to the mains Use voltage trip level is 728 V d.c. for 400 V units an 877 V d.c. for 500 V units.
