16.7 Servo Parameters
Set the gear ratio in the motor side when there is the gear between the servo motor'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".
---Setting range---
1 to 32767
Set the gear ratio in the machine side when there is the gear between the servo motor'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".
---Setting range---
1 to 32767
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 set-
tling time in positioning gets, however, note that a bigger shock will be applied to the machine during accel-
eration/deceleration.
When using the SHG control, also set SV004 (PGN2) and SV057 (SHGC).
When using the OMR-FF control, set the servo rigidity against quadrant projection or cutting load, etc. For
the tracking ability to the command, set by SV106(PGM).
---Setting range---
1 to 200 (rad/s)
When performing the SHG control, set the value of "SV003 x 8/3" to "SV004".
When not using the SHG control, set to "0".
When using the OMR-FF control, set to "0".
Related parameters: SV003, SV057
---Setting range---
0 to 999 (rad/s)
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.
---Setting range---
1 to 30000
