4.3 Setting the Initial Parameters for the Spindle Drive Unit
4.3.4 Spindle Parameters
These parameters are sent to the spindle drive unit when the NC power is turned ON. The standard parameters are
designated with the "Spindle parameter setting list" enclosed when the spindle motor is delivered. There may be cases
when the machine specifications are unclear, so the parameters determined by the machine specifications should be
confirmed by the user.
The parameters with "(PR)" requires the CNC to be turned OFF after the settings. Turn the power OFF and ON to enable
the parameter settings.
#13001 SP001 PGV Position loop gain non-interpolation mode
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 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
