To adjust the R-axis reference value,
loosen the bolts at 3 locations.
To adjust the Z-axis reference value,
loosen the bolts at 3 locations.

Step10
Shift the engagement between the motor pulley and belt tooth.
Shifting the belt engagement one tooth will change the machine reference value approximately 25%.
When shifting the pulley clockwise with the belt teeth left as they are, the reference value will increase.
Conversely, when shifting the pulley counterclockwise, the reference value will decrease.
Shift the engagement between the pulley and belt so that the Z-axis machine reference value enters a
range of 25 to 75% when compared to that confirmed in Step 4.
Step11
Tighten the plate mounting bolts.
At this time, tighten the bolts while applying an appropriate tension to the belt.
The appropriate tension can be checked as the vibration frequency is measured when the belt is
stretched. (Appropriate frequency: 50 to 53 Hz)

frequency)
308 to 398Hz
286 to 366Hz
