diagnosis
function -
Friction
judgement
speed Set a (linear) servo motor speed that divides a friction estimation area into high and
low during the friction estimation process of the machine diagnosis.
Setting "0" will set a value half of the rated speed.
When your operation pattern is under the rated speed, we recommend that you set a
half value of the maximum speed.
