MDS-D-SVJ3/SPJ3 Series Instruction Manual
3-3 Setting the initial parameters for the spindle drive unit
【#13006】 SP006 VIA1 Speed loop lead compensation 1
Set the speed loop integral control gain.
The standard setting is "1900". Adjust the value by increasing/decreasing the value by about 100.
Raise this value to improve the contour tracking accuracy in high-speed cutting.
Lower this value when the position droop does not stabilize (when the vibration of 10 to 20Hz
occurs).
---Setting range---
1 to 9999
【#13007】 SP007 VIL1 Speed loop delay compensation 1
Set this parameter when the limit cycle occurs in the full-closed loop or overshooting occurs in
positioning.
For MDS-D/DH-SP, the control method can be selected by SP033(SFNC1)/bit1,0(vcnt).
Normally, use "Changeover type 2".
When setting this parameter, make sure to set the torque offset "SP050(TOF)".
When not using, set to "0".
---Setting range---
0 to 32767
【#13008】 SP008 VGN2 Speed loop gain 2
Normally SP005(VGN1), SP006(VIA1), SP007(VIL1) are used.
By setting "SP035(SFNC3)/bit1(vgin), SP035(SFNC3)/bit9(vgn) or SP036(SFNC4)/bit1(vgs)=1",
gain 2 can be used according to the application.
Gain 2 can also be used by setting "Speed gain set 2 changeover request (control input 5/ bitC) = 1".
Refer to SP005(VGN1), SP006(VIA1), SP007(VIL1) for procedures.
---Setting range---
1 to 9999
【#13009】 SP009 VIA2 Speed loop lead compensation 2
Normally SP005(VGN1), SP006(VIA1), SP007(VIL1) are used.
By setting "SP035(SFNC3)/bit1(vgin), SP035(SFNC3)/bit9(vgn) or SP036(SFNC4)/bit1(vgs)=1",
gain 2 can be used according to the application.
Gain 2 can also be used by setting "Speed gain set 2 changeover request (control input 5/ bitC) = 1".
Refer to SP005(VGN1), SP006(VIA1), SP007(VIL1) for procedures.
---Setting range---
1 to 9999
【#13010】 SP010 VIL2 Speed loop delay compensation 2
Normally SP005(VGN1), SP006(VIA1), SP007(VIL1) are used.
By setting "SP035(SFNC3)/bit1(vgin), SP035(SFNC3)/bit9(vgn) or SP036(SFNC4)/bit1(vgs)=1",
gain 2 can be used according to the application.
Gain 2 can also be used by setting "Speed gain set 2 changeover request (control input 5/ bitC) = 1".
Refer to SP005(VGN1), SP006(VIA1), SP007(VIL1) for procedures.
---Setting range---
0 to 32767
【#13011】 SP011
Not used. Set to "0".
【#13012】 SP012
Not used. Set to "0".
