Hi waross, There is custom loom cable which boundless all the motor power cables and encoder cables, which trails the robot and where each motor's power and encoder cable are connected to its respective servo drive housed in an electrical cabinet. If I check continuity on a meter between the...

Dear Eng-Tips Community, We require a collision detection system for our robot with the plan to electrically isolate the rig from the adjacent structures and putting it at 24 VDC with a 100ohm resistor. Then when the rig contacts any of the adjacent structures the voltage will change as the...

Thanks waross for your response and your suggestions. Splitting the loads is a practical option. We'd need to rewire the junction box to accommodate the additional equipment but that shouldn't be a problem. Least we will maintain the 30mA protection. I will also evaluate the drives as you...
