II - 164
#3118 sp2_t4 Time constant in orientation/interpolation mode automatic reference
position return (Gear: 11)
Set the linear acceleration/deceleration time constant for zero point return control (#3106/
bit4,8) which is automatically started at the time of switching orientation control, C axis
control and synchronous tapping control when gear 11 is selected. The inclination is
determined by the ratio to limit rotation speed (slimit4). Set the sufficiently large value
compared to the acceleration/deceleration time constant with S command (sp_t4) so that
the output torque is not saturated. When executing C axis zero point return manually, it
depends on the axis specification parameter.
---Setting range---
0 to 30000 (ms)
#3120 staptr Time constant reduction rate in high-speed synchronous tapping
When performing high-speed synchronous tapping control(#1281/bit5), set the reduction
rate of the time constant compared to the time constant in normal synchronous tapping.
(Setting "0"or "100" will be regarded as reduction rate zero, so the time constant won't be
reduced.)
E.g.) When set to "10", time constant in high-speed synchronous tapping will be 90% of that
in normal synchronous tapping.
---Setting range---
0 to 100(%)
#3121 tret Turret indexing
Select the validity of turret indexing.
0: Invalid
1: Valid
#3122 GRC Turret side gear ratio
Set the number of teeth on the turret side when the gear selection command (control input
4/bit6, 5) is set to 00. Set a value of GRC so that the ratio of GRC to the spindle side gear
ratio (#13057 SP057) will be 1:N (an integer).
If GRC is set to "0", it will be regarded as "1".
---Setting range---
0 to 32767
#3123 tret_spd Turret indexing speed
Set the turret end indexing speed when in turret indexing.
When this parameter is set to 0, it follows the value set for Orientation command speed
(#3107).
---Setting range---
0 to 32767(r/min)
#3124 tret_t Turret indexing time constant
Set the acceleration/deceleration time constant to reach Limit rotation speed (slimt1) at gear
00 when in turret indexing. Set this parameter to a larger value than time constant in
orientation (#3115).
---Setting range---
0 to 30000 (ms)
#3125 tret_inpos Turret indexing in-position width
Set the position error range in which the index positioning complete signal is output when in
turret indexing. When this parameter is set to 0, the value of In-position width (#13024
SP024) will be used for this width.
---Setting range---
0 to 32767(1°/1000)
#3126 tret_fin_off Index positioning complete signal OFF time
Set the time to forcedly turn OFF the index positioning complete signal since the indexing
start signal turns ON. If this period of time has not passed yet, the index positioning
complete signal will not turn ON even at the completion of index positioning.
---Setting range---
0 to 10000 (ms)
#3127 SPECSP Spindle specification
bit0: Select the gear changeover method.
0: Gear change type 1 (Gear is changed when the spindle stop signal is ON and when a
gear recommended by NC and the one selected are different)
1: Gear change type 2 (Gear is changed when the spindle stop signal and spindle gear
shift signal is ON)
---Setting range---
0x0000 to 0xffff (hexadecimal)
#3128 ori_spec Orientation control specification
bit0: Orientation imposition advance output
Reduce the orientation time by detecting an in-position faster.
The in-position detection width is changed from SP024(#13024) to ori_inp2.
0: Invalid 1: Valid
---Setting range---
0x0000 to 0xffff (hexadecimal)
