Select Program➔ Set Speed Instruction to add a new instruction that changes the speed and/or the acceleration. It is possible to specify speed and accelerations in the joint space and in the cartesian space.
Activate the corresponding cases to impose a specific speed and/or acceleration in the program. The robot speed is applied from the moment this instruction is executed.
The robot speed can also be changed in the robot parameters menu: Double click the robot, then, select parameters.
