No. Items Details Setting range
2208 SV008
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).

2211 SV011
IQG
Current loop
q axis gain
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.
0 to 999
(Stall current %)
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 %)
2215 SV015
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.
0 to 999
