16.9 Spindle Parameters

#13001 SP001 PGV
Set the position loop gain for "Non-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 = 000" in control input 4.
(Note) The control mode is commanded by NC.
---Setting range---
1 to 200 (1/s)
#13002 SP002 PGN
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
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 1) The control mode is commanded by NC.
When carrying out the SHG control, set SP036/bit4 to "1".
(Note 2) Set the same value for the basic and synchronous spindles in spindle synchronization.
---Setting range---
1 to 200 (1/s)
#13004 SP004
Not used. Set to "0".
#13005 SP005 VGN1
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
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
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
IB-1501279-H
