OVERVIEW
This screen displays information pertaining to a Variable
Speed Drive (VSD).
DISPLAY ONLY
Motor Run (LED)
Indicates whether the digital output from the controls is
commanding the motor to RUN.
Motor Current % Full Load Amps
Displays the motor current as a percentage of the Full
Load Amps (FLA) value.
Current Limit Setpoint
Displays the current limit value in use. This value could
come from a 0-20mA, 4-20mA, 0-10VDC or 2-10VDC
input in Analog Remote mode, PWM signal in Digital
Remote mode, MicroGateway interface in ISN mode or
a locally programmed value.
Pulldown Demand Time Left
Displays the time remaining in the programmed pull-
down period if the value is non-zero.
Output Voltage
Displays the output voltage measured to the motor.
46
VARIABLE SPEED DRIVE SCREEN
Output Frequency
Displays the present output frequency to the motor.
Output Current - Phase A, B, C
Displays the phase current measured to the motor.
Input Power
Displays the total Kilowatts measured by the VSD or
Harmonic Filter, if installed.
kW Hours
Displays the cumulative amount of kilowatts used over
time as the VSD motor controller operates.
Pre-Rotation Vane Position
Displays the pre-rotation vane position as a value be-
tween 0 and 100%.
Harmonic Filter Data (Harmonic Filter
installed only)
Supply kVA
Displays the supply kva measured by the filter.
Total Power Factor
Displays the relationship between the Input Power and
the Supply kVA.
Voltage Total Harmonic Distortion - L1, L2, L3
Displays the Total Harmonic Distortion (THD) for each
of the voltage lines as calculated by the filter.
