LEARNED DATA
7–6
LEARNED AVERAGE kW
Range: 0.0 to 100000.0 kW in steps of 0.1 x kw
Learned average kW is the average motor real power when the motor status is Running.
The period of data window is t
AVERAGE CALC. PERIOD. If the run time of a start/stop sequence is less than t
Learned Average kW averages all available samples. The calculation is ignored during
motor starting. The data will be updated every t
Running.
LEARNED AVERAGE kvar
Range: 0.0 to 100000.0 kvar in steps of 0.1 x kvar
Learned average kvar is the average motor reactive power when the motor status is
Running. The mechanism is the same as the Learned Average kW.
LEARNED AVERAGE PF
Range: -0.99 to 1.00 in steps of 0.01
Learned average PF is the average motor power factor when the motor status is
Running. The mechanism is the same as the Learned Average kW.
AVERAGE RUN TIME (DAYS/HR/MIN)
Range: 0 to 100000 Days; 0 to 23 Hours; 0 to 59 Minutes
The average Run Time of the last N starts at the time the record was saved. If the
amount of minutes exceeds 59, the Average Run Time (Hours) is increased by one, and
this value rolls over to zero and continues. If the amount of hours exceeds 23, the
Average Run Time (Days) is increased by one, and this value rolls over to zero and
continues. N is defined by the setting in SETPOINTS > SYSTEM > MOTOR > NUMBER OF
STARTS TO LEARN.
SPEED – MAX
Range: 0 to 8200 RPM
The maximum speed is recorded. If the measured speed is greater than the maximum
value already stored, the maximum value is set to this latest value. The maximum value
is maintained in non-volatile memory to carry over a relay power interruption. The Speed
element is configured accordingly.
ANALOG INPUT 1(4) – MIN/MAX
Range: -500000 to 500000 units
The maximum/minimum analog input values are recorded. If the analog input value is
greater than the maximum value already stored, the maximum value is set to this latest
value. The maximum value is maintained in non-volatile memory to carry over a relay
power interruption. Analog Inputs elements are configured accordingly.
RTD 1(13) MAX TEMPERATURE
Range: -40 to 250°C
The maximum temperature experienced by each of the RTDs.Once a second each of the
RTD temperature values is captured. For each RTD, if the captured RTD temperature
value is greater than the RTD maximum temperature already stored, the RTD maximum
temperature is set to the latest captured RTD temperature value. The RTD maximum
temperature values are maintained in non-volatile memory to carry over a relay power
interruption. RTD elements are configured accordingly.
