RBL OVS RFF
[Data type] Bit
REF Feed forward during movement from the initial point to point R in
rigid tapping is:
0 : Disabled.
1 : Enabled.
When this parameter is set, the following function is also enabled:
• When rigid tapping is specified in advanced preview control
mode, the system automatically exits from advanced preview
control mode and executes rigid tapping. After termination of
rigid tapping, the system automatically returns to look-ahead
control mode.
RGS When bit 0 (MIF) of parameter No. 1403 is set to 1 and rigid tapping
is specified in feed-per-minute mode, the spindle speed becomes:
0 : 1/1000 of the specified speed.
1 : 1/1 of the specified speed.
OVS In rigid tapping, override by the feedrate override signal and
invalidation of override by the override cancel signal is:
0 : Disabled.
1 : Enabled.
Setting this parameter enables override by the feedrate override signal
<G012> to be applied for rigid tapping operation (cutting and
extraction) in rigid tapping.
The spindle speed override is fixed to 100%, but override is also
applied to the spindle speed in synchronization with the feedrate along
the tapping axis by feedrate override.
The override cancel signal OVC <bit 4 of G006> also becomes
available.
NOTE
1 When this parameter is set to override the feedrate,
override by parameters (see parameters Nos. 5211
(T/M) and 5381 (M)) is disabled.
2 Regardless of whether this parameter is set, when
feedrate override is disabled by the override cancel
signal OVC <bit 4 of G006>, override by
parameters (see parameters Nos. 5211 (T/M) and
5381 (M)) is enabled.
RBL As acceleration/deceleration for rigid tapping cutting feed:
0 : Linear acceleration/deceleration is used.
1 : Bell-shaped acceleration/deceleration is used.
NOTE
The bell-shaped acceleration/deceleration option
for rigid tapping is required.
