- 230 -
#7 #6 #5 #4 #3 #2 #1 #0
1749 (FS15i)
FADL
2209 (FS30i, 16i)
FADL 0: FAD bell-shaped
1: FAD linear type
* Set 1 (linear type) usually .
NOTE
To enable this bit setting, the power must be turned
off then back on.
1702 (FS15i)
Fine acc./dec. time constant (ms)
2109 (FS30i, 16i)
[Valid data range] 8 to 64 (Standard setting: 24)
A value exceeding the valid data range is clamped to the upper or
lower limit of the range.
When the fine acc./dec. and feed-forward functions are used together,
set the coefficient in the following parameter.
(The parameter No. is the same as that used for advanced preview
control.)
1985 (FS15i)
Position feed-forward coefficient (in units of 0.01%)
2092 (FS30i, 16i)
[Valid data range] 100 to 10000
NOTE
1 Feed-forward control is enabled by setting bit 1 of
No. 1883 (Series 15i) or No. 2005 (Series 16i and
so on) to 1.
2 The velocity feed-forward coefficient is set in
parameter No. 1962 (Series 15i) or No. 2069
(Series 16i and so on) which is the same
parameter as that used for normal operation.
3 Generally, the fine acc./dec. function is enabled in
cutting mode only.
4 If No. 1800 #3 = 1, the FAD function is enabled
both for cutting and rapid traverse mode.
(5) Setting parameters for the fine acc./dec. function, used separately for
cutting and rapid traverse
As mentioned above, set the fine acc./dec. function bit and the bit for
selecting the bell-shaped or linear type.
Then, set the following:
#7 #6 #5 #4 #3 #2 #1 #0
1800 (FS15i)
FFR
1800 (FS30i, 16i)
FFR 1: Enables feed-forward in rapid traverse also.
