The parameters with "(PR)" requires the CNC to be turned OFF after the settings. Turn the power OFF and 

ON to enable the parameter settings.

【#2201(PR)】   SV001   PC1   Motor side gear ratio

Set the gear ratio in the motor side when there is the gear between the servomotor's shaft and 
machine (ball screw, etc.). 
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 an initial 
parameter error (servo alarm 37) may occur. 
 
For linear servo system
Set to "1".

【#2202(PR)】   SV002   PC2   Machine side gear ratio

Set the gear ratio in the machine side when there is the gear between the servomotor's shaft and 
machine (ball screw, etc.). 
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 an initial 
parameter error (servo alarm 37) may occur. 
 
For linear servo system
Set to "1".

【#2203】   SV003   PGN1   Position loop gain 1

Set the position loop gain. The standard setting is "33". 
The higher the setting value is, the more accurately the command can be followed, and the shorter 
the settling time in positioning gets, however, note that a bigger shock will be applied to the machine 
during acceleration/deceleration. 
When using the SHG control, also set SV004 (PGN2) and SV057 (SHGC). 

1 to 200 (rad/s)

【#2204】   SV004   PGN2   Position loop gain 2

When performing the SHG control, set the value of "SV003 x 8/3" to "SV004".   
When not using the SHG control, set to "0". 
 
Related parameters: SV003, SV057

0 to 999 (rad/s)

【#2205】   SV005   VGN1   Speed loop gain 1

Set the speed loop gain. 
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 the 70 to 80% of the value at which the vibration stops. 
The value differs depending on servo motors. 
Aim at the standard value determined by the servo motor type and load inertia ratio to adjust.
