【#3103】 sp_t 3 Time constant for spindle rotation with S command (Gear: 10)
Set the acceleration/deceleration time constant for a spindle when the spindle is rotated by an S
command (spindle control mode = speed operation mode) using gear 10 (Linear acceleration/
deceleration pattern).
This parameter is also used to set the time constant for the spindle rotation when the Z-phase is
detected.
(Note) If you set this parameter to "0" by SRAM clear, etc., the time constant is equivalent to "1ms".
---Setting range---
0 to 30000 (ms)
【#3104】 sp_t 4 Time constant for spindle rotation with S command (Gear: 11)
Set the acceleration/deceleration time constant for a spindle when the spindle is rotated by an S
command (spindle control mode = speed operation mode) using gear11 (Linear acceleration/
deceleration pattern).
This parameter is also used to set the time constant for the spindle rotation when the Z-phase is
detected.
(Note) If you set this parameter to "0" by SRAM clear, etc., the time constant is equivalent to "1ms".
---Setting range---
0 to 30000 (ms)
【#3105】 sut Speed reach range
Set the speed deviation rate with respect to the commanded speed, at which the speed reach signal
will be output.
It will be 15% when set to "0".
If the speed deviation is smaller than 45r/min, it will be set as 45r/min.
---Setting range---
0 to 100 (%)
