*1 This is the J1, J2 and J4 axes' maximum speed with a control point on a flat X-Y surface. (The control point is a position 30mm from the center of the J4 axis' rotation.)
*2 Value when bearing a 2kg load. Cycle time may increase when precision workpiece positioning is necessary or due to the robot's operating position(s).
*3 Repeatability is not a guarantee of absolute precision.
*4 These are the dimensions when the J1 and J2 axes are positioned at 0°.
*5 The downwards pressing force at the tip of the load when the robot is bearing its maximum load and the J1, J2 and J4 axes are at rest. An excess load error may occur if a pressing force is applied for an extended period of time.
*6 Data is made up of job data, additional function data and PLC program data in a shared data storage area. As these data increase, the point memory capacity reduces, and the maximum number of points may become unreachable.
