7. Servo Parameters
Details
Set this when the limit cycle occurs in the full-closed
loop, or overshooting occurs in positioning.
Select the control method with SV027 (SSF1)/bit1, 0
(vcnt).
Normally, use "Changeover type 2".
When you set this parameter, make sure to set the
torque offset (SV032 (TOF)). When not using, set to
"0".
No changeover
When SV027 (SSF1)/ bit1, 0 (vcnt)=00
The delay compensation control is always valid.
Changeover type 1
When SV027 (SSF1)/ bit1, 0 (vcnt)=01
The delay compensation control works when the
command from the NC is "0".
Overshooting that occurs during pulse feeding can
be suppressed.
Changeover type 2
When SV027 (SSF1)/ bit1, 0 (vcnt)=10
The delay compensation control works when the
command from the NC is "0" and the position droop
is "0". Overshooting or the limit cycle that occurs
during pulse feeding or positioning can be
suppressed.
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).
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.
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.
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.
