9. SPINDLE SPEED FUNCTION
680
5261 Time constant for the first spindle and tapping axis (first gear stage)
5262 Time constant for the first spindle and tapping axis (second gear stage)
5263 Time constant for the first spindle and tapping axis (third gear stage)
5265 Time constant for the second spindle and tapping axis (first gear stage)
5266 Time constant for the second spindle and tapping axis (second gear stage)
[Data type] Word
[Unit of data] msec
[Valid data range] 0 to 4000
The spindle and tapping axis time constant for each gear stage is set up
for rigid tapping.
The time needed for the spindle to reach its maximum permissible
rotation speed is specified. The actual time constant is the ratio of the
maximum permissible spindle speed to the S command.
If bell–shaped acceleration/deceleration is enabled, the time constant for
the straight section is set up.
5271
Time constant for the first spindle and tapping axis for a pull–out operation
(first gear stage)
5272
Time constant for the first spindle and tapping axis for a pull–out operation
(second gear stage)
5273
Time constant for the first spindle and tapping axis for a pull–out operation
(third gear stage)
5335
Time constant for the second spindle and tapping axis for a pull–out operation
(first gear stage)
5336
Time constant for the second spindle and tapping axis for a pull–out operation
(second gear stage)
[Data type] Word
[Unit of data] msec
[Valid data range] 0 to 4000
The spindle and tapping axis time constant for each gear stage is set up
for a rigid tapping pull–out operation.
If bell–shaped acceleration/deceleration is valid, the time constant for the
straight section is set up.
NOTE
These parameters are valid if the TDR parameter (bit 2 of
parameter No. 5201) is 1.
