history and chosen overload curve. A thermal capacity value
equal to 100% causes an Overload Trip.
PHASE CURRENT
UNBALANCE = 1 %
Displays the percentage unbalance in the motor phase currents. The
unbalance is calculated as shown in Section 1.2.1: MM2 SPECIFICA-
TIONS on page 1–4.
ACCELERATION TIME =
0.0 s
This message displays the motor acceleration time from the last motor
start. This value is determined by the amount of time required for the
average phase current to go below 1.0

FULL LOAD CURRENT
after a
motor start.
LAST STARTING
CURRENT = 340 AMPS
This message displays the maximum current measured during the last
motor start. This value is saved until the next start or until power is
cycled on the MM2.
O/L TIME TO TRIP =
---- s
This message displays the estimated time to trip based on the present
overload level and thermal capacity used. This message is only used in
conjunction with overload trips.
POWER = +1000 kW This message displays the three phase power, calculated using phase

. This message will appear only if the
VT PRIMARY VOLTAGE setpoint is programmed.
ENERGY USED =
10600 kWhr
This message displays the total accumulated energy used since last
cleared. This value is updated once every minute. This message will
appear only if the VT PRIMARY VOLTAGE setpoint is programmed.
VT VOLTAGE =
480 V
This message displays the voltage present at the primary of the VT.
This message will appear only if the VT PRIMARY VOLTAGE setpoint is pro-
grammed.
ANALOG INPUT=
142 UNITS
This message displays the 4 to 20 mA analog input value scaled to the
minimum and maximum values as specified in setpoints. The analog
input name and units are user definable in the setpoints area of the
MM2 messages.
PROGRAMMABLE MESSAGE
SAMPLE TEXT
This message displays the 4 to 20 mA analog input value scaled to the
minimum and maximum values as specified in setpoints. The analog
input name and units are user definable in the setpoints area of the
MM2 messages.
