 MOTOR PROTECTION THERMAL

The motor protection (thermal) settings are programmed as follows:

•

FULL LOAD CURRENT

: Usually the rated current on the motor nameplate is entered as 

the full load current value. A lower value effectively overprotects the motor. It is not 
advisable to enter a value higher than the motor nameplate rating. When the actual 
motor current exceeds this value, the thermal capacity starts to be used up and the 
motor will eventually trip according to the overload curve selected.

•

HIGH SPEED FULL LOAD CURRENT

: This setpoint functions the same way as 

FULL 

LOAD CURRENT

, but refers to the high speed full load current (FLC) of a two-speed 

motor, and is only in effect while contactor B is energized.

•

OVERLOAD PICKUP LEVEL

: This setpoint dictates where the overload curve begins as 

the motor enters an overload condition. This is useful for service factor motors as it 
allows the pickup level to be defined. The curve is effectively cut off at current values 
below this pickup.

•

OVERLOAD CURVE NUMBER

: Select 1 of 12 different 

I

2

t

 time-overcurrent overload 

curves. Consult the overload curve figures and tables below to match the curve 
number to a particular motor. If no motor curve data is available, select the curve 
which has a 6 times overload trip time equal to the motor nameplate stall time. The 
MM3 Motor Manager 3 also has four NEMA class curves which can be selected should 
these curves be suggested by the manufacturer.

•

HOT/COLD CURE RATIO

: Defines the ratio of motor “hot” thermal characteristic to the 

motor “cold” characteristic. It is used to thermally model the heating in the motor 
when running at or below full load current. This is often determined from motor 
thermal damage curves or locked rotor time hot and locked rotor time cold data. The 

HOT/COLD CURVE RATIO

 determines the thermal capacity used when a motor has run 

at its full load current long enough for the motor temperature to reach its steady state 
value, which is defined as the hot temperature. Note that the thermal capacity used is 
reduced according to the actual motor current.
