IRB6400 M94A
50042: System error
Check: Increase the distance between close points and/or decrease speed and/or change
acceleration value.
50050: Position outside reach
Position for IRB joint %.f is outside working area. Check: Check the work object. Check
the joint working range. Move the joint in joint coordinates.
50052: Joint speed error
The speed of joint %s is too high relative the ordered speed. Check:
1. Check the tune parameters, external forces on the joint and hardware
2. Reduce programmed speed
50053: Revolution counter error.....................Chapter 9
Too big difference between the counter in the serial measurement board and the expected
value in the robot computer for joint %s. Check: Update the revolution counter. Replace
serial measurement board.
50055: Joint load error.............................Chapter 9
Actual torque on joint %s is higher than ordered. Check: May be caused by incorrect load
data, hardware error or to high acceleration.
1. Check load data
2. Check hardware
3. Reduce acceleration
50056: Joint collision error........................Chapter 9
Actual torque on joint %s is higher than ordered while at low or zero speed. Check: May
be caused by jam error (the arm has got stuck) or hardware error.
50057: Joint sync. error............................Chapter 9
The position of joint %s after power failure is too far away from the position before the
power failure. Check: Make a new update of the revolution counter.
50058: Tool coord. sys. error
The z-direction of the tool coordinate system is almost parallel with the path direction.
Check: Change the tool coordinate system to achieve at least 3 degrees deviation between
z-direction and path direction.
