	J3 overcurrent
	An overcurrent error has occurred in the V-phase of the J3 motor.
	1. Check each joint (including hand and workpieces) for no interference with surrounding devices, piping or wiring. 2. If the joint interferes with any mechanical end so as to cause this error, change the software limit or check that the CALSET operation has been correctly performed. 3. Check that the hand specifications (including workpieces) do not exceed the robot capacity. 4. Check that the robot controller cable is securely connected to the robot unit and controller. 5. Check that the FG terminals of the robot unit and controller are grounded. 6. Decrease the speed and acceleration.
