Blank
Displays no data in the selected area, allowing long messages to be
shown without overlapping.
Starter State
The starter's operating state (starting, running, stopping or tripped).
Only available for top left and bottom left positions on the screen.
Motor Current
The average current measured on three phases.
Motor pf
The motor's power factor, measured by the soft starter.
Mains Frequency
The average frequency measured on three phases.
Motor kW
The motor's running power in kilowatts.
Motor HP
The motor's running power in horsepower.
Motor Temp
The motor's temperature, calculated by the thermal model.
kWh
The number of kilowatt hours the motor has run via the soft starter.
Hours Run
The number of hours the motor has run via the soft starter.
Analog Input
The level of analog input A (see Pr 8A~8C). This setting is only
available if the input/output expansion option is installed.
Motor kVA

9F – Graph Data
The Digistart D3 has a real-time performance graph to report the behaviour of critical operating parameters.
Options:
Current (% FLC) (default)
Current as a percentage of motor full load current.
Motor Temp (%)
Motor temperature as a percentage of the motor's thermal capacity.
Motor kW (%)
Measured motor kilowatts, as a percentage of maximum kW.
Motor kVA (%)
Measured motor kilovolt amperes, as a percentage of maximum kVA.
Motor pf
Motor power factor, measured by the soft starter.
Measured motor kW:
√
3 x average current x mains reference voltage x measured power
factor
Maximum motor kW:
√
3 x motor FLC x mains reference voltage. Power factor is assumed
to be 1
Measured motor kVA:
√
3 x average current x mains reference voltage
Maximum motor kVA:
