2) The motor power line is shorted or grounded.
3) Mechanical load is added on axis.
4) Tension of the timing belt is not proper.
5) Arm is bound.
6) Axis #3 brake cannot be released.
7) Arm hit an obstacle.
8) Other than the above.
1) Eliminate external noise source and execute
VERINIT command. (Refer to the section 2.6
in the functions volume.)
If no external noise source exists, replace the MPU
board. (Refer to the section 7.3 in the mainte-
nance volume.)
2) Check disconnection of the motor power line in
manipulator and controller. (Refer to the ma-
nipulator manual and “2.3 Diagram of cable
connection” in the maintenance volume of this
manual.)
3) Check each axis motion moving by the hand.
Verify appropriate lubrication or replace the re-
