16 Machine Parameters
#3109 zdetspd
For the first S command after power is turned ON, the spindle rotates at the speed of setting value for this
parameter until Z phase is detected twice.
When "#3106/bitF = 1" (Spindle zero point proximity switch detection enabled), also proximity switch is de-
tected.
(Note) When spindle zero point proximity switch detection is enabled, the rotation direction of the orientation/
zero point return (synchronous tapping, spindle/C axis) will follow Z phase detection direction. And the
speed will follow Z phase detection speed.
---Setting range---
1 to 99999 (r/min)
#3110 tap_spd
Set the zero point return speed during synchronous tapping control.
---Setting range---
1 to 99999 (r/min)
#3111 tap_sft
Set the zero point return shift amount during synchronous tapping control. Zero point angle shifts from Z
phase according to the setting angle.
---Setting range---
0 to 35999 (0.01°)
#3112 cax_spd
Set the zero point return speed during spindle C axis control.
---Setting range---
1 to 99999 (r/min)
#3113 cax_sft
Set the spindle C axis zero point return shift amount. Zero point angle shifts from Z phase according to the
setting angle.
---Setting range---
0 to 359999 (0.001°)
#3114 cax_para_chg
Parameter switches when switching the encoder system between normal spindle control and C axis control,
such as using spindle side encoder only for C axis control in spindle drive system. It is validated with replacing
a certain servo parameter of the corresponding servo axis to a spindle parameter.
0: Not switch
1: Switch
---Setting range---
0/1 (Standard: 0)
#3115 sp2_t1
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 00 is selected. The inclination is determined by the ratio to limit rotation speed (slimit1). Set the
sufficiently large value compared to the acceleration/deceleration time constant with S command (sp_t1) 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)

Spindle C axis zero point return speed
Spindle C axis zero point return shift amount
Spindle/C axis parameter switch

matic reference position return (Gear: 00)
