Also note that the keypad fault LED blinks whenever M10B07 (IxT
ALARM) is set to “1”
See Figure 10-3a. for graphical definition of the M05P54 (IxT BREAK
FREQ) and M05P55 (IxT ZER FRQ THLD) parameters. These two
parameters define the continuous operation zone of the motor.
The M05P18 (OVERLOAD TIME) parameter determines how long the
motor can run outside the continuous operation zone before it will
thermally trip.
General purpose (TEFC) motors
cannot run at high torque
levels while at low speed continuously.
This is because the
cooling for the motor is supplied by a fan that is driven by the motor
shaft. As the speed of the motor decreases, the flow of air supplied by
the fan decreases and the less cooling there is. For this type of motor,
the proper motor thermal overload protection curve can be matched to
the motor thermal time constant by setting the M05P55 (IxT ZERO FRQ
THLD) parameter to 60.0% and the M05P54 (IxT BREAK FREQ)
parameter to the M05P09 (BASE MOTOR FREQ) value. This means at
zero speed the motor can safely draw 60.0% rated motor current
indefinitely without overheating. At base speed, the motor can safely
draw its full load rated current due to full cooling capability. See Figure
10-3c.
For Blower-Cooled (TENV) motors, running at high torque
levels at low speed can be tolerated.
This is because the cooling
for the motor is supplied by a separately powered blower that provides
the same volume of cooling air, regardless of the motor speed. For this
type of motor, the proper motor thermal overload protection curve can
be matched to the motor thermal time constant by setting the M05P55
(IxT ZERO FRQ THLD) parameter to 100.0% and the M05P54 (IxT
BREAK FREQ) parameter to the M05P09 (BASE MOTOR FREQ) value.
This means at zero speed, the motor can safely draw 100% rated
motor current indefinitely without overheating. Also, at base speed,
the motor can safely draw its full load rated current due to full cooling
capability. See Figure 10-3b.
