SV047 EC Inductive voltage compensation gain
Set the inductive voltage compensation gain. Standard setting value is "100".
If the current FB peak exceeds the current command peak, lower the gain.
---Setting range---
0 to 200 (%)
【
#2248
】
SV048 EMGrt Vertical axis drop prevention time
Input the time required to prevent the vertical axis from dropping by delaying READY OFF until the
brake works at an emergency stop.
Increase in increments of 100ms at a time, find and set the value where the axis does not drop.
When using a motor with a break of HF(-H) Series or HP(-H) Series, set to "200ms" as a standard.
When the pull up function is enabled (SV033/bitE=1), the pull up is established during the drop
prevention time.
Related parameters: SV033/bitE, SV055, SV056
---Setting range---
0 to 20000 (ms)
【
#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).
When changing the value, change the value of "#2017 tap_g Axis servo gain".
---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)
【
#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 (
