MDS-D2/DH2 Series Instruction Manual
4.3 Setting the Initial Parameters for the Spindle Drive Unit
【#3114】 cax_para_chg Spindle/C axis parameter switch
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 Time constant in orientation/interpolation mode automatic reference
position return (Gear: 00)
Set the linear acceleration/deceleration time constant for zero point return control (#3106/bit4,8)
which is automatically 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)
【#3116】 sp2_t2 Time constant in orientation/interpolation mode automatic reference
position return (Gear: 01)
Set the linear acceleration/deceleration time constant for zero point return control (#3106/bit4,8)
which is automatically 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 Time constant in orientation/interpolation mode automatic reference
position return (Gear: 10)
Set the linear acceleration/deceleration time constant for zero point return control (#3106/bit4,8)
which is automatically 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 Time constant in orientation/interpolation mode automatic reference
position return (Gear: 11)
Set the linear acceleration/deceleration time constant for zero point return control (#3106/bit4,8)
which is automatically 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)
