【#13002】 SP002 PGN Position loop gain interpolation mode
Set the position loop gain for "interpolation" control mode.
When the setting value increases, the command tracking ability will enhance and the
positioning settling time can be shorter. However, the impact on the machine during
acceleration/deceleration will increase.
Use the selection command, the control mode "bit 2, 1, 0 = 010 or 100" in control input 4.
(Note) The control mode is commanded by NC.
When carrying out the SHG control, set SP035/bitC to "1".
---Setting range---
1 to 200 (1/s)
【#13003】 SP003 PGS Position loop gain spindle synchronization
Set the position loop gain for "spindle synchronization" control mode.
When the setting value increases, the command tracking ability will enhance and the
positioning settling time can be shorter. However, the impact on the machine during
acceleration/deceleration will increase.
Use the selection command, the control mode "bit 2, 1, 0 = 001" in control input 4.
(Note) The control mode is commanded by NC.
When carrying out the SHG control, set SP036/bit4 to "1".
---Setting range---
1 to 200 (1/s)
【#13004】 SP004
Not used. Set to "0".
【#13005】 SP005 VGN1 Speed loop gain 1
Set the speed loop gain.
Set this according to the load inertia size.
The higher setting value will increase the accuracy of control, however, vibration tends to
occur.
If vibration occurs, adjust by lowering by 20 to 30%.
The final value should be 70 to 80% of the value at which the vibration stops.
---Setting range---
1 to 9999
【#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.
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) is used.
By setting "SP035/bit1, SP035/bit9 or SP036/bit1=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) for adjustment procedures.
---Setting range---
1 to 9999
【#13009】 SP009 VIA2 Speed loop lead compensation 2
Normally SP006(VIA1) is used.
By setting "SP035/bit1, SP035/bit9 or SP036/bit1=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 SP006(VIA1) for adjustment procedures.
---Setting range---
1 to 9999
【#13010】 SP010 VIL2 Speed loop delay compensation 2
Normally SP007(VIL1) is used.
By setting "SP035/bit1, SP035/bit9 or SP036/bit1=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 SP007(VIL1) for adjustment procedures.
---Setting range---
0 to 32767
【#13011】 SP011
Not used. Set to "0".
