REGISTER Data description
EVENT1 • Phase currents L1, L2, L3 and the NPS current as a multiple of the rated
current, I , which corresponds to the FLC of the motor. The earth fault
n
current, I , as a percentage of the rated current of the CT used. When a
0
stage generates a start or an alarm signal, or when a motor start up ends,
the maximum currents during the pick-up period will be stored. When a stage
trips, the values at the time of the trip will be stored.
• Thermal stress value, I
2
I x t . If start-up supervision based on thermal stress calculation has been
s s
selected and the start criteria for the stage have been met, the maximum
calculated thermal stress value will be stored. The value 100% indicates that
the calculated thermal stress has exceeded the set reference value.
• Number of motor start ups. The number indicates the motor start up during
which the event was stored and provides history data since last
commissioning. Writing to parameter V53 will reset the number of motor start
ups.
• Thermal level, as a percentage of the maximum thermal level of the motor, at
activation of a start, alarm or motor start-up signal.
• The maximum thermal level during the time the start, alarm or motor start-up
signal was active, as a percentage of the maximum thermal level of the
motor, or in case of a trip, the thermal level, as a percentage of the maximum
thermal level of the motor, at activation of a trip signal.
• The temperatures from inputs RTD1...6 (optional) and the resistance values
of thermistors 1 and 2 (optional). When a stage generates a start or an alarm
signal, or when a motor start up ends, the maximum temperature(s) and
thermistor resistance value(s) during the pick-up period will be stored. When
a stage trips, the temperatures and resistance values at the time of trip will
be stored.
• Duration of the last starts of stages I
alarms and trips of stages ThA> (optional) and ThB> (optional), expressed
as a percentage of the set or calculated operate time. The timing will start
when a stage starts. The elapsed operate times of stages ThA> and ThB>
for the RTD input which has been activated the longest in their respective
groups. A value other than zero indicates that the corresponding stage has
started whereas the value 100% indicates that the operate time of the stage
has elapsed, i.e. the stage has tripped. If the operate time of a stage has
elapsed but the stage is blocked, the value will be 99% of the set or
calculated operate time.
• Time stamp for the event. The time when the collected data was stored. The
time stamp is displayed in two registers, one including the date expressed as
yy-mm-dd, and the other including the time expressed as HH.MM; SS.sss.
