#7 #6 #5 #4 #3 #2 #1 #0
REF PKD RCK
5205
REF NRV RCK
[Data type] Bit
RCK In rigid tapping, an excessive error during movement/at stop is:
0 : Checked regardless of whether mode is cutting (tapping) or rapid
traverse.
1 : Checked only in cutting (tapping) mode.
NRV For the rigid tapping function, the spindle returns back from the
bottom of a hole with:
0 : Rotating opposite to the drilling direction
1 : Rotating in the drilling direction (special purpose)
CAUTION
This parameter is intended for special uses only.
When rigid tapping is performed, therefore, this
parameter must not be set.
If rigid tapping is performed with this parameter set,
a tapping tool, workpiece, or machine may be
damaged.
PKD For rigid peck tapping, diagnostic number 457 (maximum rigid
tapping synchronization error) indicates:
0 : A value per tap operation.
1 : A total value until the hole bottom is reached.
REF Fine acceleration/deceleration during rigid tapping is:
0 : Disabled.
1 : Enabled.
To use the spindle fine acceleration/deceleration (FAD) function, set
1.
NOTE
When fine acceleration/deceleration is used, fine
acceleration/deceleration settings for the spindle
and servo system must be made in addition to the
setting of this parameter.
5210 Rigid tapping mode specification M code
[Data type] Byte
[Valid data range] 0 to 255
This parameter sets an M code that specifies the rigid tapping mode.
NOTE
1 A setting value of 0 is assumed to be 29 (M29).
2 To use an M code whose number is greater than
256, Specify the code number with parameter
No.5212.
