VIA 

Speed loop 
lead compen- 
sation 

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).

2212 SV012 

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. 

1 to 4096 

2213 SV013 

ILMT 

Current limit 
value 

Set the normal current (torque) limit value. (Limit values 
for both + and - direction.) 
When the value is "500" (a standard setting), the 
maximum torque is determined by the specification of the 
motor.

2214 SV014 

ILMTsp 

Current limit 
value in 
special 
control 

Set the current (torque) limit value in a special control 
(initial absolute position setting, stopper control, etc). 
(Limit values for both of the + and - directions.) 
Set to "500" when not using. 

0 to 999 
(Stall current %)

FFC

 

Acceleration 
rate feed 
forward gain 

When a relative error in the synchronous control is large, 
apply this parameter to the axis that is delaying. The 
standard setting value is "0".  For the SHG control, set to 
"100". 
To adjust a relative error in acceleration/deceleration, 
increase the value by 50 to 100 at a time.
