- 196 -
NOTE
Note that the two-stage backlash acceleration
cannot be used together with the backlash stop
function.
Second stage acceleration is not completed by nature until a distance
specified by "Second stage end scale factor" is moved. For example, if
only several microns are moved after the direction is reversed, second
stage acceleration continues. To prevent such continued acceleration
from occurring, set a maximum allowable duration of time with the
parameter below.
1769 (FS15i)
Two-stage backlash acceleration end timer
2146 (FS30i, 16i)
[Unit of data] ms
[Typical setting] 50
<9> Second stage acceleration adjustment
The two-stage backlash acceleration function has effect even if
only first stage is used. However, a protrusion may linger
because of machine friction. In such a case second stage is
useful.
Adjust the second stage acceleration so that it falls in a range
where no cut occurs.
1724 (FS15i)
Second stage acceleration amount for two-stage backlash acceleration
2039 (FS30i, 16i)
[Typical setting] 100 (Too large a value could cause a cut at low feedrate.)
NOTE
When second stage acceleration is not used, set
second stage acceleration amount = 0. The setting
of second stage start position = 0 alone cannot
disable second stage acceleration.
