MDS-D-SVJ3/SPJ3 Series Instruction Manual
3-3 Setting the initial parameters for the spindle drive unit
【#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 this parameter 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, the value of Orientation command speed (#3107 ori_spd) will be
used for the turret indexing speed.
---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 (#3001 slimt) at gear 00
when in turret indexing (linear acceleration/deceleration pattern). Set this parameter to a larger
value than #3115 sp2_t1 at gear 00.
---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
1: Gear change type 2
---Setting range---
0x0000 to 0xffff (hexadecimal)
【#3128】 ori_spec Orientation specification
bit0: Orientation imposition advance output
0: Invalid
1: Valid
---Setting range---
0x0000 to 0xffff (hexadecimal)
【#3129】 cax_spec Spindle/C axis specification
Not used. Set to "0".
