#3116 sp2_t2
Set the linear acceleration/deceleration time constant for zero point return control (#3106/bit4,8) which is au-
tomatically started at the time of switching orientation control, C axis control and synchronous tapping control
when gear 01 is selected. The inclination is determined by the ratio to limit rotation speed (slimit2). Set the
sufficiently large value compared to the acceleration/deceleration time constant with S command (sp_t2) 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)
#3117 sp2_t3
Set the linear acceleration/deceleration time constant for zero point return control (#3106/bit4,8) which is au-
tomatically started at the time of switching orientation control, C axis control and synchronous tapping control
when gear 10 is selected. The inclination is determined by the ratio to limit rotation speed (slimit3). Set the
sufficiently large value compared to the acceleration/deceleration time constant with S command (sp_t3) 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)
#3118 sp2_t4
Set the linear acceleration/deceleration time constant for zero point return control (#3106/bit4,8) which is au-
tomatically 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
When performing high-speed synchronous tapping control(#1281/bit5), set the reduction rate of the time con-
stant 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 syn-
chronous tapping.
---Setting range---
0 to 100(%)
#3121 tret
Select the validity of turret indexing.
0: Invalid
1: Valid
#3122 GRC
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
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)
Time constant in orientation/interpolation mode auto-
matic reference position return (Gear: 01)
Time constant in orientation/interpolation mode auto-
matic reference position return (Gear: 10)
Time constant in orientation/interpolation mode auto-
matic reference position return (Gear: 11)

nous tapping
