Yamaha YK250XGC Installation Manual page 37

Before using the robot (Be sure to read the following notes.)
Thank you for purchasing YAMAHA SCARA ROBOT YK-XGC(P) series.
This manual describes only the points that are different from the standard models.
For details about other explanations, see the Installation Manual and Maintenance Manual for YK-XG series
standard models.
1. If the Z-axis spline vibrates.
The Z-axis spline of the YK250XGC(P), YK350XGC(P), YK400XGC(P), YK500XGLC(P), and YK600XGLC(P) tends to
vibrate in a Z-axis operation speed range of 20% to 40%. If the Z-axis spline vibrates, operate it beyond this operation
speed range.
2. If the machine harness projects toward the base rear side.
In the YK250XGC(P), YK350XGC(P), YK400XGC(P), YK500XGLC(P), and YK600XGLC(P), the machine harness may
project toward the base rear side according to the arm position.
The maximum projection amount is described in "1.2 External view and dimensions" in Chapter 5. So, refer to this
section for further information.
