16 Machine Parameters
#3124 tret_t
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
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
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
bit3: Spindle rotation direction
Define the relationship between the motor's actual direction of rotation and the spindle rotation signals
(Spindle forward run start/Spindle reverse run start).
0: Forward
1: Reverse
bit1: Spindle cycle counter direction
Specify whether the cycle counter counts up or down during the spindle forward run.
0: Count up during forward run
1: Count down during forward run
bit0: Output conditions of spindle changeover mode and spindle speed reach signals
0: Conventional operation
Spindle changeover mode signal
When the spindle stop signal is ON and when a gear recommended by NC and the one selected in
ladder program are different, the spindle changeover mode signal is output to the spindle drive unit.
Spindle speed reach signal
Spindle speed reach signal is turn ON/OFF according to the FB signal.
1: Operation when the gear responds to the neutral state under full-closed control
Spindle changeover mode signal
When both the spindle stop signal and the spindle gear shift signal are ON, the spindle changeover
mode signal is output to the spindle drive unit.
Spindle speed reach signal
During gear changeover (while gear changeover is being commanded), the spindle speed reach sig-
nal is turned ON/OFF according to the virtual spindle-end speed that is calculated by multiplying the
motor-end speed by the gear ratio (motor-end gear teeth/spindle-end gear teeth).
---Setting range---
0x0000 to 0xffff (hexadecimal)
