This version instruction set system contains 44 instructions in all. Letters are not case-sensitive. All
instructions, whether were sent or returned, there will be "carriage line breaks (\r\n)" as a
command ending character. All system parameters can be grouped into the Immediate variable
parameter and non-immediate parameters, these parameters will be saved (EEPROM). The rest will
be lost (RAM).
Immediate variable parameter is that user setting takes effect immediately (Note: need to perform
"EEPSAV" to saves all present configuration parameters in order to ensure those will not lost if
power off), including each motor’s acceleration/deceleration, PID parameters asynchronously and
synchronous speed (Note: asynchronous and synchronous speed are in detail below).
Non-Immediate variable parameter is that parameter which will work in next start. It will be stored in
the EEPROM first, after the system was reset, it can take effect.
To allows user to easily analyze the return directive package, Except the directives "read drive
configuration parameter", all configuration parameters will be singular form.
3.1 Query drive type (ID,PING\r\n)
The type of Veyron motor drive series can be accessed through this command, such as: send the
command to brush DC motor drive, it returns "BDC\r\n".
* Send: 1,PING\r\n
* Return: BDC\r\n
3.2 Read the drive configuration parameters (ID,RCONFIG\r\n)
Through this directive, you could get all the configuration parameters of the drive, after you set the
parameters, you can query parameter whether it has been changed according to the requirements with
this directive, if it has been changed, and it had to be saved in the EEPROM, it’s available to use
"save all current configuration parameter" command which will be mentioned bellow, then the
parameters can be saved.
* Send: 1,RCONFIG\r\n
* Returns: (drive all configuration parameters)
3.3 Restore factory settings (ID,FCONFIG\r\n)
All configuration parameters restore to factory settings with this command, drive will automatically
reset once receiving the instruction and allow the configure to factory parameters.
* Send: 1,FCONFIG\r\n
* Returns: none
3.4 Query Help (ID,HELP\r\n)
The instruction help you get the wiki address of DFRobot products, user can search the drive models
