B-63950EN/02 4.DESCRIPTION OF PARAMETERS
- 273 -
In interpolation type rigid tapping, linear/bell-shaped acceleration/
deceleration of constant acceleration time type is used. So, set a time
constant directly for the spindle and tapping axis for each gear.
NOTE
These parameters are enabled when the parameter
TDR (bit 2 of parameter No.5201) is set to 1.
5280
Position control loop gain for the spindle and tapping axis in rigid tapping
(common to gears)
5281
Position control loop gain for the spindle and tapping axis in rigid tapping
(first gear)
5282
Position control loop gain for the spindle and tapping axis in rigid tapping
(second gear)
5283
Position control loop gain for the spindle and tapping axis in rigid tapping
(third gear)
Position control loop gain for the spindle and tapping axis in rigid tapping
(fourth gear)
5284
[Input type] Parameter input
[Data type] Word spindle
[Unit of data] 0.01/sec
[Valid data range] 1 to 9999
Each of these parameters is used to set a position control loop gain for
the spindle and tapping axis in rigid tapping. These parameters
significantly affect the precision of threading. Optimize these
parameters as well as the loop gain multipliers by conducting a cutting
test.
NOTE
To use a varied loop gain on a gear-by-gear basis,
set parameter No.5280 to 0, and set a loop gain for
each gear in parameters No.5281 to No.5284. The
specification of a loop gain on a gear-by-gear basis
is disabled if parameter No.5280 is set to a value
other than 0. In such a case, the value set in
parameter No.5280 is used as a loop gain that is
common to all the gears.
