Each of these servo drives provides a control signal to its corresponding motor through a plurality of wires connected to plugs mounted on the motion panel. From the motion panel, cables connect to plugs mounted on an explosion-proof box on the paint sprayer still life oil paintings.
The length of these cables, up to 50 meters, will vary for each sprayer because each sprayer is a different distance from the motion portrait oil paintings panel. Similarly, feedback signals from the motor pass through the explosion-proof box to another set of plugs, where cables of varying length up to 50 meters carry the signals to the plugs mounted on the motion panel, where a plurality of wires carry the feedback signals to the servo drive.
For each axis of each paint sprayer landscape oil paintings, three limit switches are typically used to provide additional feedback to the computer. The limit switches indicate overtravel in each direction on each axis and indicate a "home" position on that axis. The signals from the limit switches are carried to a junction box mounted on each paint sprayer. Cables connect plugs on a junction box on each paint sprayer to plugs mounted on the motion panel. In the motion panel, intrinsic safety barriers are connected between the plugs on the motion panel and IDC connectors. Ribbon cables carry the feedback signal from the IDC connectors to the motion card.
