5 Servo Adjustment
293
IB-1501229-F
< Adjustment method >
[1] Set the servo specifications (SV017: SPEC)/bit1 to 1, and turn the NC power ON again.
[2] Measure the position droop overshooting while increasing the dual feedback control time constant (SV051:
DFBT) in increments of 5ms. Adjust to the time constant where overshooting does not occur.
[3] For the final setting value, set a value 1.5 to 2-fold the value adjusted in 3.

#2217(PR)
】
SV017 SPEC1 Servo specification 1
bit 1 : dfbx Dual feedback control
Control the position FB signal in full closed control by the combination of a motor side encoder and
machine side encoder.
0: Stop 1: Start
【
#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".
---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".
---Setting range---
0 to 9999 (
