we have an old Nachi Robot with a E0072(H ) Current in drive unit exceeded limit error
it is erroring out frequently and in different locations each time (not hitting an obstruction)
we tried to follow the troubleshooting flow in the manual and it basically says to check if the wires are loose... they aren't.
any ideas what can cause this or how to troubleshoot further?
does the (H ) in the error code signify a certain axis?
thanks for the help
