Panel composition

The panel composition of the VD2 series servo drive is shown in Figure 5-1 (take VD2A servo drive as an example).

The panel of the VD2 series servo drive consists of a display (5-digit LED nixie tube) and keys, which can be used for the execution of various displays, parameter settings and other functions of the servo drive. Taking parameter setting as an example, the general functions of the keys are shown in Table 5-1.

Icon	Name	Function
	Mode	Mode switching Return to the previous menu
	Increase	Increase the value of the LED flashing bit
	Decrease	Decrease the value of the LED flashing bit
	SHIFT key	Change the LED flashing bit View the high-bit value of data with a length greater than 4-bit
	Enter (OK)	Enter the next menu Execute commands such as storing parameter setting values

Table 5-1 key functions

Panel display

When servo drive is in operation, the panel could be used for status display, parameter display, fault display and monitoring display of the servo.

• Status display: Display the current operating status of servo drive.
• Parameter display: Display the function codes corresponding to different functions and the set values of the function codes.
• Fault display: Display the fault code of servo drive.
• Monitor display: Display the current operating parameter values of servo drive.

Display switching

Illustrate:

1. The power is turned on, and the panel display of the servo drive enters “Status Display Mode”.
2. After an operation failure occurs, the panel immediately switches to the bit failure display mode. At this time, all the nixie tubes flash synchronously. Press the "mode" key to switch to the parameter display mode.
3. Press the "Mode" key to switch between different display modes, and the switching conditions are shown in Figure 5-2.

Status display

Display	Display occasion	Meaning
	Servo drive is powered on within 1 second	Servo drive is in initialization status
	Very short time after displaying "88888"	Initialization is complete
	1 second after servo drive is powered on, servo is ready	The servo is ready, waiting for the enable signal given by servo drive
	Servo enable signal is valid	The servo drive is in an operational status, waiting for the instructions from host computer
	Servo drive is in jog operation	Jog operation settings

Table 5-2 Status display example

Parameter display

VD2 series servo drives are divided into 13 groups of function codes according to different parameter functions, which could quickly locate the position of function codes according to the function code groups. For the specific parameters refer to “9 Parameters".

Parameter group display

The parameter display is the display of different function codes. The format of the function code is “PXX.YY”. “PXX” indicates the group number of function code, and “YY” indicates the number within the function code group.

For example: The function code P00.01 is displayed as follows.

Display	Name	Content
	Function code P00.01	00: Function code group number 01: Number in the function code group

Display of different length data

Display Data with four bits and below

• Using single page display, if it is a signed number, the highest bit of the data is "-".
• For example: The monitoring volume U0-02 is displayed as follows.

Display	Name	Content
	Monitoring volume U0-02	Servo motor speed

Display Data more than five bits

• Display in pages from low to high bits, and each 4 bits is a page. Display method: current page + current value.as shown in Figure 5-3 and Figure 5-4, switch current page by pressing the "Shift" key.
• For example: 2147483646 is displayed as follows:

For example: -2147483647 is displayed as follows:

Decimal point display

The "." of the one-digit indicates the decimal point, and it does not flash. The example is as follows.

Display	Name	Content
	Decimal point	302.4

Parameter setting display

Display	Name	Display occasion	Meaning
	Done Parameter setting completed	Parameter reset factory	The servo drive is in the process of parameter factory reset
	P.Init Parameter reset factory	Parameter reset factory	The servo drive is in the process of parameter factory reset
	Error Parameter error	Parameter setting exceeds the limit (or not allowed to exceed the limit)	Prompt that the parameter setting exceeds the limit

Table 5-3 Parameter setting display

Fault display

The panel can display current or historical fault and warning codes. For analysis and troubleshooting of faults and warnings, please refer to "10 Malfuctions" .

When a single fault or warning occurs, the panel immediately displays the current fault or warning code;

when multiple faults or warnings occur, the highest fault code is displayed. When a fault occurs, when switching from the auxiliary function to the parameter display function, the corresponding fault or warning code will be displayed. You can view the current fault and warning codes and the past five fault and warning codes through the monitor display on the panel.

Display	Name	Content
	Parameter modification that needs to be powered on again	Modified the parameters that need to be re-powered to take effect

Table 5-4 Warning display example

Display	Name	Content
	Motor overload protection	Motor overload protection

Table 5-5 Fault display example

Monitor display

After the servo drive is powered on or the servo enable is ON, you can press the "Mode" key to enter the monitor display mode.

Display	Monitoring volume	Name	Unit	Meaning
	U0-02	Servo motor speed	rpm	Indicates the actual operating speed of servo motor, expressed in decimal.
	U0-31	Bus voltage	V	Indicates the voltage value between P+ and - of the drive, the DC bus voltage
	U0-17	Input signal status	-	Indicates the level status corresponding to the 8 DI terminals. The upper half of the LED light indicates high level, and the lower half light indicates low level. (The VD2F model has only 4 DI ports)
	U0-19	Output signal status	-	Indicates the level status corresponding to the 4 DO terminals. The upper half of the LED light indicates high level, and the lower half light indicates low level.

Panel operation

Parameter setting

Use the servo drive panel to set the parameters. For details about the parameters, please refer to " 9 Parameters". Take P00.01 as an example to set the parameters to change the control mode of the servo drive from position control mode to speed control mode. The setting steps are shown in Figure 5-5.

Illustrate:

• The power supply is in Rdy state after power on.
• Press "Mode" key to enter the function code parameter interface.
• Press "Confirm" key to enter the function code value modification interface after completing the function code selection.
• Press the "Up" and "Down" keys to modify the parameter value.
• Press the "Confirm" key twice to complete the value modification.

Jog operation

In order to test run the servo motor and the servo drive, you can use the jog running function. The operation steps are shown in Figure 5-6.

Illustrate:

• Adjust the function code to P10.01 after power on.
• Press the "Enter" key to enter the next menu to set the JOG jog speed.
• After the “JOG jog speed” setting is completed, press the "Enter" key, the panel displays “JOG” in a flashing state, press the "Enter" key again to enter the JOG mode.
• Long press the "Up" key and "Down" key to realize the forward and reverse rotation of the motor.
• Press the "Mode" key to exit the JOG mode.
• Reason for displaying Error: Please refer to “10 Malfunctions" according to the corresponding fault codes.

Factory reset

The factory settings can be restored through the servo drive panel. The specific operation steps are shown in Figure 5-7.

Illustrate:

• After power on, modify the function code to P10.02.
• Press the "Enter" key to enter the next menu to set the parameters.
• Press the "Confirm" button after the parameter setting is finished, and the setting value will flash.
• Press "Confirm" again, the panel digital tube will light up gradually from left to right until 8.8.8.8.8 is displayed.
• Finally it displays “Done”, the servo drive will be re-powered and the operation of factory reset is finished.
