16 Machine Parameters
#13040 SP040 LMCT
Set the non-sensitive band of the lost motion compensation in the feed forward control.
When "0" is set, 2°/1000 is set. Adjust by increasing the value by 1°/1000 at a time.
---Setting range---
-32768 to 32767 (1°/1000)
#13041 SP041 LMC2
Set this parameter with SP048(LMC1) only to vary the lost motion compensation amount depending on the
command directions.
Normally, set to "0".
---Setting range---
-1 to 200 (Short-time rated %)
Note that when SP227/bit2 is "1", the range will be -1 to 20000 (Short-time rated 0.01%).
#13042 SP042 OVS2
Set this parameter with SP043(OVS1) only to vary the lost motion compensation amount depending on the
command directions.
Normally, set to "0".
---Setting range---
-1 to 100 (Short-time rated %)
Note that when SP227/bit2 is "1", the range will be -1 to 10000 (Short-time rated 0.01%).
#13043 SP043 OVS1
Set this parameter when overshooting occurs during positioning. This compensates the motor torque during
positioning.
This is valid only when the overshooting compensation SP033 (SFNC1/ovs) is selected.
[Type 3 "When SP033/ bitB,A=11"]
Use this when performing overshoot compensation in the feed forward control during arc cutting mode.
Set the compensation amount based on the motor short-time rated current.
Increase the value in increments of 1% to find the value where overshooting ceases.
[To vary compensation amount depending on the direction]
When SV042 (OVS2) is "0", change the SP043 (OVS1) value in both +/- directions to compensate.
To change the compensation amount depending on the command direction, set this with SP042 (OVS2).
(SP043: + direction, SP042: - direction, However, the directions may be opposite depending on other set-
tings.)
When "-1" is set, the compensation will not be performed in the command direction.
---Setting range---
-1 to 100 (Short-time rated %)
Note that when SP227/bit2 is "1", the range will be -1 to 10000 (Short-time rated 0.01%).
#13044 SP044 OBS2
Set the disturbance observer gain. The standard setting is "100".
To use the disturbance observer, also set SP037(JL), SP045(OBS1) and SP226/ bitE.
When not using, set to "0".
---Setting range---
0 to 500 (%)
#13045 SP045 OBS1
Set the disturbance observer filter band.
Normally, set to "100".
To use the disturbance observer, also set SP037(JL), SP044(OBS2) and SP226/ bitE.
When not using, set to "0".
---Setting range---
0 to 1000 (rad/s)
