6.23 Spindle Orientation
II - 55
6.23.2 Orientation Operation
When Z-phase has not yet been passed, pass Z-phase twice (excluding reciprocations within one rotation), and then
position to the orientation position.
When Z-phase has been passed already, immediately position to the orientation position.
The spindle does not rotate if Z-phase has been passed and the orientation position is already established when
orientation command is issued.
When the spindle has been rotating in the direction opposite from that of orientation rotation when the orientation
command is issued, orientation operation will be executed after decelerating to stop.
(1) The acceleration/deceleration patterns at orientation/position loop reference position return
For the acceleration/deceleration patterns at orientation/position loop reference position return (C axis, tapping), the time
constant is set by the parameter "#3115 sp2_t1" to "#3118 sp2_t4" (Time constant in orientation/position loop reference
position return). The orientation acceleration/deceleration time is calculated with the following expression.
(Example: The acceleration/deceleration time for gear 00)
For position loop reference position return, the parameter "#3110 tap_spd" (Synchronous tapping zero point return
speed) or "#3112 cax_spd" (Spindle C axis zero point return speed) is used for position loop reference position return (C
axis, tapping) instead of the orientation command speed.
In any case, when "#3101 sp_t 1" is larger than "#3102 sp_t 2" (Time constant for spindle rotation with S command),
"#3101 sp_t 1" is used.
