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.

(PR) 

SV002 
PC2 

Machine side 
gear ratio 

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.

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 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).

2204 SV004 

PGN2 

Position loop 
gain 2 

When using the SHG control, also set SV003 
(PGN1) and SV057 (SHGC). 
When not using the SHG control, set to “0”. 

0 to 999

2205 SV005 

VGN1 

Speed loop 
gain 

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.

2208 SV008 

VIA 

Speed loop 
lead 
compensation 

Set the gain of the speed loop integration control. 
The standard setting is “1364”.  During the SHG 
control, the standard setting is “1900”.  Adjust the 
value by increasing/decreasing it by about 100 at a 
time. 
Raise this value to improve contour tracking 
precision in high-speed cutting.  Lower this value 
when the position droop vibrates (10 to 20Hz).

IDG 

Current loop d 
axis gain 

Set the gain of current loop. 
As this setting is determined by the motor’s electrical 
characteristics, the setting is fixed for each type of 
motor. 
Set the standard values for all the parameters 
depending on each motor type.
