II - 94
【#3117】 sp2_t3 Time constant in orientation/position loop reference position return (Gear:
10)
Set the acceleration/deceleration time constant to reach the spindle's limit speed (slimt),
when spindle rotates in orientation/position loop zero point return method (C axis, tapping)
using gear 10 (Linear acceleration/deceleration pattern).
(Note 1) Set a value that is bigger than the values set by "#3101 sp_t1 to #3104 sp_t4".
(Note 2) If you set this parameter to "0" by SRAM clear, etc., the time constant is equivalent
to "1ms".
If this parameter is set to an illegal value, this parameter follows the setting of "sp_t1
to sp_t4".
---Setting range---
0 to 30000 (ms)
【#3118】 sp2_t4 Time constant in orientation/position loop reference position return (Gear:
11)
Set the acceleration/deceleration time constant to reach the spindle's limit speed (slimt),
when spindle rotates in orientation/position loop zero point return method (C axis, tapping)
using gear 11 (Linear acceleration/deceleration pattern).
(Note 1) Set a value that is bigger than the values set by "#3101 sp_t1 to #3104 sp_t4".
(Note 2) If you set this parameter to "0" by SRAM clear, etc., the time constant is equivalent
to "1ms".
If this parameter is set to an illegal value, this parameter follows the setting of "sp_t1
to sp_t4".
---Setting range---
0 to 30000 (ms)
【#3119】 ext_clp External spindle speed clamp feedrate
Set the external spindle speed clamp feedrate.
The value is compared to each command feedrate of spindle when the external spindle
speed clamp signal is ON. The smaller federate will be applied for operation.
---Setting range---
0 to 99999 (r/min)
【#3120】 staptr Time constant reduction rate in high-speed synchronous tapping
When performing high-speed synchronous tapping, 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(%)
【#3127】 SPECSP Spindle specification
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 signal 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)
【#3130】 syn_spec Spindle synchronization specification
bit1: Acceleration/ deceleration type in phase alignment
0: Phase alignment method Type 2 (Acceleration/ deceleration method)
1: Phase alignment method Type 1 (Step alignment method)
【#3140(PR)】 S_DINSp Speed monitor input door No.
Set the door signal input in the drive unit.
Use this parameter only when the axis with a door signal belongs to several door groups.
The correspondence between the door signals and bits are as follows.
bit0 : Door1 signal
bit1 : Door2 signal
:
bitF : Door16 signal
If the axis does not receive any door signal, set to "0".
An error (Y20 0027) will occur in the following cases.
- Several bits are enabled.
- Any bit other than those set in "#3071 S_DSlSp" is enabled.
---Setting range---
0000 to FFFF (HEX)
