ABB ACS880 - Settings and Diagnostics; Voltage Control and Trip Limits

If the DC voltage is restored before the expiration of the period defined by parameter
21.18 and the start signal is still on, normal operation will continue. However, if the DC
voltage remains too low at that point, the drive trips on a fault, 3280.
Settings and diagnostics
Parameter: 21.18 Auto restart time (page 259).
Event: 3280 Standby timeout (page 544).
￭ Voltage control and trip limits
The control and trip limits of the intermediate DC voltage regulator are relative to the
supply voltage as well as drive/inverter type. The DC voltage is approximately 1.35
times the line-to-line supply voltage, and is displayed by parameter 1.11.
All levels are relative to the supply voltage range selected in parameter 95.1. The
following table shows the values of selected DC voltage levels in volts and in percent
of U
DCmax
(the DC voltage at the upper bound of the supply voltage range).
