Put timer during Z-axis operation. 3.
If the tip load attached to the spline tip of the YK250XGC(P), YK350XGC(P), YK400XGC(P), YK500XGLC(P), or
YK600XGLC(P) exceeds 2kg, the Z-axis may be overloaded depending on the operation pattern.
In this case, put a timer during operation as shown in the Fig. below to prevent overload of the Z-axis. The reference
timer values are shown below. Furthermore, the maximum payload is 4kg. If the tip load exceeds this maximum payload,
the Z-axis may be overloaded easily. So, do not operate the robot with a tip load exceeding 4kg.
