Action
Install the axis-4 belt tension adjustment tool to
the motor.
Note
Just tighten the tool.
Use a handheld dynamometer hooking to the
screw and pull the dynamometer to make the
tension falling in the allowed force range.
Note
During the measurement, make sure that all inter-
ferences that may affect the force are removed.
Pay attention to the force application direction.
Tip
If the ball screw will interfere with the handheld
dynamometer, adjust the ball screw manually.
