Looking to set up a linear actuator like the one linked below:


What would be the best way of connecting it up? it comes with analog positional feedback. was looking into connecting it into a h bridge

    I made a quick check of the datasheet of the liniar actuator.

    It looks like the best will be to use this actuator in combination with a control board:

    You can also contact the support of Actuonix.

    It is probably better to use this controller than making your own control solution.

    That is the board in intend to use after a bit of research. I was just looking to know the way to wire it the the UR

    Looks like there are different type of control possible.

    4–20 mA Interface Mode: This mode is compatible with PLC devices typically used in industrial control applications. The desired actuator position (set-point) is input to the LAC on connector X6 pin 4 as a current between 4 mA and 20 mA. The set-point current must be held on pin 4 to reach and maintain the desired actuator stroke position.  

    4-20 mA Interface Mode looks good.
    • Connect the actuator on X2
    • Connect controller digital output to X6 pin4
    • Connect controller ground on X6 pin 1
    • Connect controller 24V on X6 pin 2
    On UR you have the possibility to control a digital output in mA (14-20mA).

    I hope it helps

     X6 pin 4 is connected to D04 which is fine. is the power and ground from an external power source or can it be done with the robot for X6 pin 1 and 2. Could you give more info on controlling digital output in mA.

    Looks like supply voltage of the control board must match actuator’s rated voltage. So I was wrong with the connection on controller 24V. Probably the best is to use and external 12V power supply.

    I hope it helps,

    I you want to confirm information the best is to contact the supplier of this actuator.

    If using an external power supply for the DO, it is just a case of putting 12V to the 24V and 0V on the Power block
