Double click the program to start the program simulation.
Alternatively:
1.Right click the program
2.Select Run
A simulation bar will appear at the bottom if the program is double clicked. It is possible to slide the simulation to move the simulation forward or backwards using the simulation bar.
RoboDK simulates 5 times faster than real time by default. That means that if a program takes 30 seconds to execute it will be simulated in 30/5=6 seconds. Speeding up the simulation increases this ratio to 100. Normal and fast simulation speeds can be changed in the Tools➔Options➔Motion menu.
