Operation and Display
Parameters used to program the fundamental functions of the adjustable frequency drive and
the LCP including:
•
Selection of language.
•
Selection of which variables are displayed at each position in the display. As an example,
static duct pressure or condenser water return temperature can be displayed with the
setpoint in small digits in the top row and feedback in large digits in the center of the
display).
•
Enabling/disabling of the LCP keys.
•
Passwords for the LCP.
•
Upload and download of commissioned parameters to/from the LCP.
•
Setting the built-in clock.

Load/Motor
Parameters used to configure the adjustable frequency drive for the specific application and
motor including:
•
Open or closed-loop operation.
•
Type of application such as:
-
Compressor
-
Fan
-
Centrifugal pump
•
Motor nameplate data.
•
Auto-tuning of the adjustable frequency drive to the motor for optimum performance.
•
Flying start (typically used in fan applications).
•
Thermal motor protection.
2-**
Brakes
Parameters used to configure brake functions of the adjustable frequency drive, which, although
not common in many HVAC applications, can be useful in special fan applications. Parameters
include:
•
DC brake.
•
Dynamic/resistor brake.
•
Overvoltage control (which provides automatic adjustment of the deceleration rate
(auto-ramping) to avoid tripping when decelerating large inertia fans).
