It is shown in Figure 4-3.
In running state, there are 24 parameters that can be selected for display, including
running frequency, set frequency, bus voltage, output voltage, output current, running
speed, output power, output torque, PID reference value, PID feedback value, input
terminal status, output terminal status, torque setting, length value, PLC and the current
step of multi-step speed, AI1, AI2, AI3, high-speed pulse HDI frequency, motor overload
percentage, VFD overload percentage, ramp reference value, linear speed, and AC input
current. P07.05 and P07.06 can select the parameter to be displayed or not by bit, and
you can press 》 /SHIFT to shift selected parameters from left to right or press
QUICK/JOG to shift selected parameters from right to left.

4.2.3 Displaying fault information

After detecting a fault signal, the VFD enters the fault alarm state immediately, the fault
code blinks on the keypad, and the TRIP indicator is on. You can perform fault reset by
using the STOP/RST key, control terminals, or communication commands.
If the fault persists, the fault code is continuously displayed.

4.2.4 Editing function codes

You can press the PRG/ESC key to enter the editing mode in stopped, running, or fault
alarm state (if a user password is used, see the description of P07.00). The editing mode
contains two levels of menus in the following sequence: Function code group or
function code number → Function code setting. You can press the DATA/ENT key to
enter the function parameter display interface. On the function parameter display
interface, you can press the DATA/ENT key to save parameter settings or press the
PRG/ESC key to exit the parameter display interface.
