(1) Details for servo parameters
For parameters marked with a (PR) in the table, turn the NC power OFF after setting. After the power is
turned ON again, the parameter is validated.
! CAUTION
In the explanation on bits, set all bits not used, including blank bits, to "0".

7. Servo Parameters
Set the motor side and machine side gear ratio.
For the rotary axis, set the total deceleration
(acceleration) ratio.
Even if the gear ratio is within the setting range, the
electronic gears may overflow and cause an alarm.
Set the position loop gain. The standard setting is
"33".
The higher the setting value is, the more precisely
the command can be followed and the shorter the
positioning time gets, however, note that a bigger
shock is applied to the machine during
acceleration/deceleration.
When using the SHG control, also set SV004
(PGN2) and SV057 (SHGC).
When using the SHG control, also set SV003
(PGN1) and SV057 (SHGC).
When not using the SHG control, set to "0".
Set the speed loop gain.
Set this according to the load inertia size.
The higher the setting value is, the more accurate
the control will be, however, vibration tends to occur.
If vibration occurs, adjust by lowering by 20 to 30%.
The value should be determined to be 70 to 80% of
the value at the time when the vibration stops.
If the noise is bothersome at high speed during rapid
traverse, etc, lower the speed loop gain.
As in the right figure, set the speed loop gain of the
speed 1.2 times as fast as the motor's rated speed,
and use this with SV029 (VCS).
When not using, set to "0".
