MOTOR DATA
MOTOR
STATUS:
This message indicates the name and status of the motor. The top line
of the display (20 characters) can be programmed to a user defined
alphanumeric name. The second line indicates motor status. The fol-
lowing list shows the possible motor status indications:
•
Unavailable
: There is at least one condition present that is prevent-
ing start commands from operating. Possible conditions are: a trip is
present, the STOP key is being pressed, the Stop Switch input is
open, one of the Process Interlock switches is open, an undervolt-
age delayed restart is in progress, an Autotransformer Start Inhibit
is in progress, or the STARTER TYPE setpoint is OFF.
•
Available-Auto
: Start commands from the serial port or the Auto
Start A / Auto Start B interlock switch inputs will be performed. Start
commands from the Start A / Start B switch inputs and the START
A/ START B keys will be ignored.
•
Available-Manual
: Start commands from the Start A / Start B switch
inputs and/or the START A/ START B keys will be performed. Start
commands from the serial port and Auto Start A / Auto Start B
switch inputs will be ignored.
•
Running
: At least one contactor output relay is closed.
A= 74 B= 74
C= 74 AMPS
This message displays the actual RMS current in each phase in amps.

50 A.
GROUND CURRENT =
2.4 AMPS
This message displays the ground fault leakage current flowing from
any phase to ground in amps.
MOTOR LOAD =
74% FULL LOAD
This message displays the motor load as a percentage of full load cur-
rent (FLC). The motor load is calculated as the average of the three
motor phase currents. When the value exceeds 100%, an overload con-
dition exists. The MM2 eventually trips if the current is not reduced
below 100% of FLC
