Low voltage variable speed drive screen

Figure 28: Low voltage variable speed drive screen
This screen displays information about the Low Voltage Variable Speed Drive (VSD), if installed.
There are two similar screens available: one for VSD 1 and another for VSD 2.

Description
Indicates whether the digital output from the controls is commanding the motor to
RUN.
Indicates whether the digital output from the controls is commanding the optional
motor heater on. This LED is not displayed if the option is not installed.
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, 4
mA to 20 mA, 0 VDC to 10 VDC, or 2 VDC to 10 VDC input in Analog Remote mode, PWM
signal in Digital Remote mode, SC-EQ communications interface in ISN (BAS) mode, or
a locally programmed value.
Displays the Pre-rotation Vane position as a value between 0% and 100%.
Displays the time remaining in the programmed pulldown period if the value is
nonzero.
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.
Displays the Total Harmonic Distortion (THD) for each of the voltage lines as calculated
by the optional filter.
Displays the Total Dynamic Distortion (TDD) for each of the supply current lines as
calculated by the optional filter.
Displays the supply kVa measured by the optional filter.
Displays the relationship between the Input Power and the Supply kVA when the
optional filter is installed.
