Appendix 1 Explanation of Parameters
【#3143(PR)】 spsscfeed3 Safety observation speed 3
Set the safety observation speed, which is at the machine end, in the multi-step speed monitor mode
3.
(Note) The lower two digits of the setting value are ignored. An input value "1234567" is recognized
---Setting range---
0 to 1800000 (°/min)
【#3144(PR)】 spsscfeed4 Safety observation speed 4
Set the safety observation speed, which is at the machine end, in the multi-step speed monitor mode
4.
(Note) The lower two digits of the setting value are ignored. An input value "1234567" is recognized
---Setting range---
0 to 1800000 (°/min)
【#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
300
as "1234500", "99" is "0".
as "1234500", "99" is "0".
