Variable speed drive screen
Figure 22: Variable speed drive screen
This screen displays information pertaining to the Variable Speed Drive (VSD).
Table 37: Display only fields
Field/LED name Description
Motor Run (LED)
Indicates whether the digital output from the controls is commanding
the motor to RUN.
VSD Fault (LED)
Indicates the VSD is reporting a fault over the communications link or by
logic low at the hardwired digital input.
Input % Full Load Amps
Displays the input current as a percentage of the job Full Load Amps
(FLA) value, based on the highest phase.
Input Current Limit
Setpoint
Displays the input 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, SC-Equip Gateway interface in BAS
(ISN) mode, or a locally programmed value.
Pulldown Demand
Time Left
Displays the time remaining in the programmed pulldown period if the
value is nonzero.
VSD Output Voltage Displays the output voltage measured to the motor.
VSD Output Frequency Displays the present output frequency to the motor.
Max Chiller Frequency
Displays the maximum value that the Output frequency is limited to for
the chiller, based on configuration.
Input Power Displays the total input Kilowatts measured by the VSD.
Input kW Hours
Displays the cumulative amount of kilowatts used over time as the VSD
motor controller operates.
