DISPLAY PARAMETERS
The Display parameters, described in the following tables, can be viewed in any access level from the
Display Menu. Use the arrow keys on the keypad display or programming terminal to scroll through this
parameter set. The following parameters can be viewed under Drive State in the Display Menu. They
are used for monitoring drive controller operation.
The following parameters can also be viewed from the Display Menu.
Parameter STATUS Description
Drive State RDY Drive controller is ready to run.
RUN Drive controller and motor are running in a steady state.
ACC Drive controller is accelerating the motor.
DEC Drive controller is decelerating the motor.
CLI Drive controller is in current limit.
DCB Drive controller is injecting DC current for braking the motor.
NST Drive controller has been commanded to freewheel stop.
OBR Drive controller is decelerating the motor as fast as possible.
Parameter Units Description
Reference Frequency Hz
Displays the frequency the drive controller is commanded to run. (If using the keypad to
control the drive, the speed reference can be entered at this screen.)
Output Frequency Hz Displays the output frequency being applied to the motor.
Motor Speed rpm Motor speed in RPM based on user specified motor RPM.
Motor Current A Current being drawn by the motor.
Machine Speed ---
Value displayed based on user specified scaling factor multiplied by the output
frequency. The scaling factor has a range of 0.01 to 100.
Output Power %
Displays the percent of power the being drawn by the motor.
100% corresponds to nominal current rating of the drive.
Line Voltage Volts Displays the voltage measured at the input of the drive.
Motor Thermal %
Displays the thermal state of the motor.
100% corresponds to nominal motor thermal state.
Drive Thermal %
Displays the thermal state of the drive controller.
100% corresponds to nominal drive controller thermal state.
Last Fault
The following faults can be displayed:
Input phase loss Undervoltage Overvoltage,
Drive overheating Motor overload Overbraking
Motor phase loss Loss of 4-20mA signal Overcurrent
Motor short circuit Pre-charge fault Loss of RS-485
Motor overheating Thermal senor fault EEPROM fault
Internal fault External fault Overspeed
