Apply the PID with this configuration without adding a sensor

@cbenson it’s very good it works well, thank you very much.
Now I will work with arduino and I want to understand this code where it will display and read positions, currents, voltages, temperatures.

#include <LSS.h>    
// ID set to default LSS ID = 0
    #define LSS_ID		(0)
    #define LSS_BAUD	(LSS_DefaultBaud)

    // Create one LSS object
    LSS myLSS = LSS(LSS_ID);

    void setup()
    {
    	// Initialize the LSS bus
    	LSS::initBus(Serial, LSS_BAUD);
    }

    void loop()
    {
    	// Header 1
    	Serial.println("\r\nQuerying servo...");

    	// Get LSS position, speed, current, voltage, temperature
    	int32_t pos = myLSS.getPosition();
    	uint8_t rpm = myLSS.getSpeedRPM();
    	uint16_t current = myLSS.getCurrent();
    	uint16_t voltage = myLSS.getVoltage();
    	uint16_t temp = myLSS.getTemperature();

    	// Header 2
