Description
Displays the pre-rotation vane position as a value between 0 and 100%.
Indicates whether the digital output from the controls is commanding the motor to
run.
Displays the motor current as a percentage of the Full Load Amps (FLA) value.
Displays the current limit value in use. This value could come from a 0 mA to 20
mA, 0 VDC to 10 VDC, PWM signal, or SC-EQ communication interface, or a locally
programmed value.
Displays the output voltage measured to the motor.
Displays the present output frequency to the motor.
Displays the total kilowatts measured by the VSD or Harmonic Filter, if installed.
Displays the cumulative amount of kilowatts used over time as the VSD motor
controller operates.
Displays the phase current measured to the motor.
(L1, L2, L3) Displays the Total Harmonic Distortion (THD) for each of the voltage lines
as calculated by the filter (displayed if Harmonic Filter is present).
(L1, L2, L3) Displays the Total Dynamic Distortion (TDD) for each of the supply current
lines as calculated by the filter (displayed if Harmonic Filter is present).
