FLA Full load current (amperes). Set to maximum stator
continuous RMS current primary (actual motor winding)
amperes in each phase. Use motor nameplate or
manufacturers data. Note that the ratio FLA/CT prim
must lie between 0.25 and 1.5 in order to have reliable
motor protection.
10 - 6000A 10A [System Para]
LRC Set to the locked-rotor current (the current the motor
draws when stalled), in times of FLA. Use motor
nameplate or manufacturers data.
3.00 - 12.00FLA 3.00FLA [System Para]
LRTC Specifies how long a locked-rotor or stall condition can
be maintained before the motor is damaged, in seconds,
for a cold start. Use motor nameplate or manufacturers
data.
1 - 120s 1s [System Para]
UTC Ultimate trip threshold. Sets the current level above
which a trip will eventually occur when no RTD stator
temperature data is available, in multiple of FLA. For
normal use, set UTC to the service factor times 100%.
The service factor is found on the motor nameplate or in
manufacturers data.
0.85 - 1.50 0.85 [System Para]
STPC Stop current threshold, in multiple of FLA, if the actual
current is below the threshold for at least 300
milliseconds. If a stop state occurs, the jogging functions
Starts per Hour Allowed (SPH), Time Between Starts
(TBS) and Anti-Backspin (ABK) are enforced. All phases
of the current must be below this level before a stop will
be declared.
