1. Product Introduction
The LED keyboard consists of two rows of digital tubes, nine indicator lights, six button
and one number knob; the first row is used for monitoring parameters and auxiliary
display, and the second row is used for parameter setting, operatiol control and
monitoring.
The appearance of the LED keyboard is shown in Figure 1-1:

2. Hierarchical display and menu mode
The display of the VFD500 dual-line display LED keyboard is divided into two lines, the
first line is used for monitoring and auxiliary display, and the second line is used for
switching monitoring, menu mode, function code selection, parameter editing and
viewing.
The menu is divided into four types: standard mode, user-defined mode, calibration
mode, LED setting mode.
◆Standard Mode（-bSC-）
If the access authority (P00.01) is the standard, all function codes mentioned in the
VFD500 user manual can be accessed.
If the access authority (P00.01) is the end user (in the state where the user password is

5
locked), Then only individual function codes can be accessed.
◆User-defined mode（-USr-）
In this menu mode, only 20 groups of user-defined parameters are displayed.
◆calibration mode（-vrF-）
In this menu mode, only the parameters that differ from the factory values are
displayed.
Note: The forward rotation of the knob will display the next function code, the reverse
rotation will not respond.
◆ LED setting mode（-LEd-）
In this mode, PAr.00-PAr.03 can be set and viewed. This parameter belongs to the
keyboard's own parameters and will be automatically stored in the keyboard's eeprom
before power off.

3. Operation example
The three switchable interfaces after power-on, the respective operations are as
follows:
The interface can be switched by the [ESC] button.

(1) Monitoring status interface
When the monitoring status interface is stopped, the default monitoring parameters are
determined by function code P21.12, and the default monitoring parameters are
determined by P21.11 during operation. At this time, you can switch and view the set
monitoring parameters through the [SHFIT] butt

Note:
1)Dual-line monitoring cannot monitor "32-bit data" and "binary data".
2)In the monitoring state of the second line, rotate “UP and DOWN” to set the
frequency or torque in real time. For details, see function code P21.13 (the default
factory setting is P00.07, and the rotary knob will take effect immediately after the
change).
4. digital tube display
◆Display of decimal data
16 digits:
The display range for unsigned numbers is 0 to 65535 (excluding the decimal point),
the display range for signed numbers is -9999 to 32767 (excluding the decimal point),
and negative numbers less than -9999 will be displayed as -9999.

9
32 digits:
Dot1 is used to distinguish between the upper and below screens, Light up means the
up screen displayed (high 5 digits)，Off means down screen displayed (lower 5 digits).
The display range of 32-bit unsigned numbers is 0 ~ 4294967295.
As shown 4294967295:
Dot1
◆Binary data display
Binary numbers currently only support 16 digits, which are displayed on the up and
down screen.
The leftmost digital tube is used to distinguish the up and down screens: the top
segment lights up to indicate the up screen, and the bottom segment lights up to
indicate the down screen.
Excluding the leftmost digital tube, from top to bottom are Bit15 ~ Bit0. The upper
segment is lit to indicate 1, and the lower segment is lit to indicate 0.

10
Lower screen, lower 8
digits
Upper screen, high 8

bit1=1
bit0=0
bit15=0
◆Parameter attribute identification
The leftmost digital tube of the editable parameter displays "P"; The leftmost digital
tube of the read-only parameter displays "r", Show as the picture:
“P”means can be edit
“r”means read only
◆Specific symbol
In some states, the digital tube will display a specific symbol. The meaning of specific
symbols is shown in the table below:
Symbol
Significance
tUnE
Motor parameter self-learning
bUSY
Processing parameter read and write requests

Er.xxx
-Fault code, "XXX" is the fault type, For details,
please refer to "VFD500 User Manual
Troubleshooting"
Cr.xxx
Communication failure code, "XXX" is the failure
type, Cr.001-Cr005 represents the data error, Cr.006
is the communication timeout, and Cr.007 is the CRC
check error.
PAr.xxx
The LED's own parameters can be set in the "LEd"
menu mode, see "LED Setting Mode (-LEd-)" for
details.
