Home > Robotiq Products > I can't connect to gripper.(Hand-E)
SamLee

I am using the UR5e by connecting the Hand E. However, the gripper is not connected.
So, I connected the gripper to the PC and tried to check the gripper's status with the Robotiq User Interface.
Even using the RUI, there was no connection to the gripper. So I checked "with any Slave ID" and connected it, and it was connected.
How can I solve this problem?

Hi @SamLee,

If you could connect by checking the "with any Slave ID" box, it means that the RTU Slave ID of your gripper is not at its default value (which is 9).

Once connected to the RUI, you may go to the Modbus RTU tab to change its slave ID to 9 (9 is equal to ID 1 in the UR interface). the URCap supports ID9, 2, 3, and 4 if it is to be used with other grippers at the same time. 

Hope this helps,
SamLee

I changed the slave id to 9 with RUI as you said. (default button) However, if "with any slave id" is not checked, the connection is not made.
