Mains Monitor Menu
5.6.1. Overview
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: in that case,
when the mains is out of range, the regenerative drive is temporarily disabled but no alarm trips. Parameters
P570
to
P575
set the activation/deactivation of each control.
The default values of certain parameters may be automatically assigned to the values imposed by the
regulations in force concerning mains voltage and frequency variations. By setting
P576
to a value other
than zero, the parameters affected by the selected regulations as well as their access rights will be
automatically updated. Parameter
P576
may be changed within
12 hours
from the latest modification.
Afterwards, the setting in
P576
becomes permanent.
