II - 96
【#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".
【#13012】 SP012
Not used. Set to "0".
【#13013】 SP013
Not used. Set to "0".
【#13014】 SP014 PY1 Minimum excitation rate 1
Set the minimum value for the variable excitation rate. The standard setting is "50".
Set to "0" when using an IPM spindle motor.
If noise including gear noise is loud, select a small value. However, a larger setting value is
more effective for impact response.
(Note) When setting a value at "50 or more", check if there is no problem with gear noise,
motor excitation noise, vibration during low-speed rotation or vibration when the servo is
locked during orientation stop, etc.
When setting a value at "less than 50", check if there is no problem with the impact load
response or rigidity during servo lock.
---Setting range---
0 to 100 (%)
【#13015】 SP015 PY2 Minimum excitation rate 2
Normally, SP014(PY1) is used.
By setting "SP035/bit2, SP035/bitA or SP036/bit2=1", the excitation rate 2 can be used
according to the application.
The excitation rate 2 can also be used by setting "the minimum excitation rate 2 changeover
request (control input 5/ bitB) = 1". Refer to SP014(PY1) for adjustment procedures.
Set to "0" when using an IPM spindle motor.
---Setting range---
0 to 100 (%)
