3.6 Description of Displays
The WFC HT Series Inverter has been designed to provide the
greatest level of information possible to the operator through an
easily readable 2x16 character Back Lit LCD alpha-numeric
display, including data on drive and motor status, fault
information and parameter values. This section will give a brief
description of the various display formats that may be seen
during startup, operation and programming.
The restart display is present whenever
power is applied to the inverter or a fault
condition is reset. It will be displayed for
about one second during which time the
computer is checking various functions within
the inverter.
During normal operation, the operating
display will provide important information
about the inverter and load.
CONTROL
The first three characters of the top line denote the source of control for the inverter:
LOC Local control via the Keypad
REM Remote control from the terminal strip
SIO Remote control via the RS485 Serial SIO Link
SEQx Control via the Program Sequencer
ADJ Auto-tune mode for Parameter 5B-IMAG
STATUS
Twelve characters are dedicated to the current status of the inverter output. This includes normal operating
conditions and warning messages:
STOP The inverter is in the STOP mode.
ACCELERATE The motor is increasing in speed.
DECELERATE The motor is decreasing in speed.
AT SPEED
Motor speed is at the desired set point.
ZERO SPEED The inverter is in the RUN mode, but the motor is not turning.
JOG
Motor runs only while the FWD or REV keys are pressed. (Displayed only while
JOGGING).
TORQ LIMIT The output torque of the inverter has reached its programmed limit level.
DYN BRAKE The Dynamic Braking circuit is helping to decelerate the motor and load.
HI TEMP The temperature of the drive is near the maximum limit point.
HI CURRENT The output current is near the overcurrent cutoff point.
HI VOLTAGE The voltage on the DC bus is near the high voltage cutoff point.
LO VOLTAGE The voltage on the DC bus is near the low voltage cutoff point.
SPD SEARCH Autostart has been programmed to 82-START, and the inverter is attempting to
synchronize its output with the motor speed.
IDLE#xx SIO mode of operation only. The drive is programmed to SIO address (92-SIOA) = xx.
It is awaiting either a program or run command.
LS LOCKOUT Line Start Lockout. A run command was detected when power was applied.
MODE
The first three characters on the second line denote the present operating mode of the inverter:
FWD A Forward run command has been given.
REV A Reverse run command has been given.
SET The inverter is waiting to have, or is having, the running frequency set.
FREQUENCY
The standard display shows the inverter operating frequency in Hertz. This can be custom tailored to any
engineering or machine units by the setting of parameters 84-DISP and 85-UNITS.
LOAD
The last four characters in line 2 display the percentage of maximum continuous inverter output current that is
being delivered. If a custom display is programmed on this line, this information is not displayed but is still
viewable at parameter 15-LOAD.
