MDS-D-SVJ3/SPJ3 Series Instruction Manual
4-3 Gain adjustment
(2) Setting the position loop gain for spindle synchronous control
During spindle synchronous control (synchronous tapping control, etc.), there are three sets of position
loop gain parameters besides the normal control.
【#2249】 SV049 PGN1sp Position loop gain 1 in spindle synchronous control
Set the position loop gain during spindle synchronization control (synchronous tapping and
synchronization control with spindle C-axis).
Set the same value as that of the position loop gain for spindle synchronous tapping control.
When performing the SHG control, set this parameter with SV050 (PGN2sp) and SV058 (SHGCsp).
---Setting range---
1 to 200 (rad/s)
【#2250】 SV050 PGN2sp Position loop gain 2 in spindle synchronous control
When using SHG control during spindle synchronous control (synchronous tapping and
synchronization control with spindle C-axis), set this parameter with SV049 (PGN1sp) and SV058
(SHGCsp).
Make sure to set the value 8/3 times that of SV049.
When not using the SHG control, set to "0".
---Setting range---
0 to 999 (rad/s)
【#2258】 SV058 SHGCsp SHG control gain in spindle synchronous control
When using SHG control during spindle synchronization control (synchronous tapping and
synchronous control with spindle C-axis), set this parameter with SV049 (PGN1sp) and SV050
(PGN2sp).
Make sure to set the value 6 times that of SV049.
When not using the SHG control, set to "0".
---Setting range---
0 to 1200 (rad/s)
Always set the same value for the position loop gain between the spindle and servo synchronous
axes.
