【#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)
【#2251】 SV051 DFBT Dual feedback control time constant
Set the control time constant in dual feed back.
When "0" is set, it operates at 1ms.
The higher the time constant is, the closer it gets to the semi-closed control, so the limit of the
position loop gain will be raised.
For linear servo/direct-drive motor system
Not used. Set to "0".
Related parameters: SV017/bit1, SV052
---Setting range---
0 to 9999 (ms)
【#2252】 SV052 DFBN Dual feedback control non-sensitive band
Set the non-sensitive band in the dual feedback control.
Normally, set to "0".
For linear servo/direct-drive motor system
Not used. Set to "0".
Related parameters: SV017/bit1, SV052
---Setting range---
0 to 9999 (μm)
【#2253】 SV053 OD3 Excessive error detection width in special control
Set the excessive error detection width when servo ON in a special control (initial absolute position
setting, stopper control and etc.).
When "0" is set, excessive error detection will not be performed when servo ON during a special
control.
---Setting range---
0 to 32767 (mm)
However, when SV084/bitC=1, the setting range is from 0 to 32767 (μm).
(Only for MDS-D/DH and MDS-DM)
【#2254】 SV054 ORE Overrun detection width in closed loop control
Set the overrun detection width in the full-closed loop control.
When the gap between the motor side detector and the linear scale (machine side detector) exceeds
the value set by this parameter, it will be judged as overrun and "Alarm 43" will be detected.
When "-1" is set, the alarm detection will not be performed.
When "0" is set, overrun will be detected with a 2mm width.
For linear servo/direct-drive motor system
Not used. Set to "0".
---Setting range---
-1 to 32767 (mm)
However, when SV084/bitD=1, the setting range is from -1 to 32767 (μm).
(Only for MDS-D/DH and MDS-DM)
