MAINS MONITOR MENU
3.6.1.
O
VERVIEW
The Mains Monitor menu includes the parameters defining the max. variation thresholds of the mains ratings if
compared to the rated values (Rated Mains Voltage, C500; Rated Mains Frequency, C501) during the
equipment operation.
The mains frequency/voltage values are monitored, which must not exceed or drop below the ranges set in the
parameters of the Mains Monitor menu. Alarm trip can be disabled by setting C502 = NO (C502 is factory
set to YES); in that case, when the mains is out of range, the regenerative drive is temporarily disabled but no
alarm trips (the motor drive enable depends on C503). Parameters P570 to P574 set the
activation/deactivation of each control (factory setting: all controls are activated).
