4.3 Setting of Current Limiting Value at Pressing Operation
When having a pressing operation, set up the current limiting value which determines the pressing
force.
The graph below shows the current against the pressing force.
Take this as a reference for when making an adjustment to the pressing force.
There is no limit to the pressing duration. Continuous pressing can be performed.

Caution: • The pressing force is adjusted with the current limiting value, and the fluctuation of
pressing force gets big when the current limiting value is low. It is recommended to
use the product in the range from 60% to 80% if possible.
• There may be a difference in the pressing force due to the variation of each unit or a
difference in the pressing position.
• Setting from 71% to 80% for the current limiting value may not be performed for
some versions of the PC software and teaching pendant.
