SV040 LMCT Lost motion compensation non-sensitive band
Set the non-sensitive band of the lost motion compensation in the feed forward control.
When "0" is set, 2
μ
m is the actual value to be set. Adjust increments of 1
μ
m.
---Setting range---
0 to 255 (
μ
m)
【
#2241
】
SV041 LMC2 Lost motion compensation 2
Set this with SV016 (LMC1) only when you wish to vary the lost motion compensation amount
depending on the command directions.
Normally, set to "0".
---Setting range---
-1 to 200 (Stall current %)
Note that when SV082/bit2 is "1", the setting range is between -1 and 20000 (Stall current 0.01%).
【
#2242
】
SV042 OVS2 Overshooting compensation 2
Set this with SV031 (OVS1) only when you wish to vary the overshooting compensation amount
depending on the command directions.
Normally, set to "0".
---Setting range---
-1 to 100 (Stall current %)
Note that when SV082/bit2 is "1", the setting range is between -1 and 10000 (Stall current 0.01%).
【
#2243
】
SV043 OBS1 Disturbance observer filter frequency
Set the disturbance observer filter band.
Normally, set to "100". Setting values of 49 or less is equal to "0" setting.
To use the disturbance observer, also set SV037 (JL) and SV044 (OBS2).
When disturbance observer related parameters are changed, lost motion compensation needs to be
readjusted.
Set to "0" when not using.
---Setting range---
0 to 1000 (rad/s)
【
#2244
】
SV044 OBS2 Disturbance observer gain
Set the disturbance observer gain. The standard setting is "100 to 300".
To use the disturbance observer, also set SV037 (JL) and SV043 (OBS1).
When disturbance observer related parameters are changed, lost motion compensation needs to be
readjusted.
Set to "0" when not using.
---Setting range---
0 to 500 (%)
【
#2245
】
SV045 TRUB Friction torque
Set the frictional torque when using the collision detection function.
To use load inertia estimation function (drive monitor display), set this parameter, imbalance torque
(SV032) and load inertia display enabling flag (SV035/bitF).
---Setting range---
0 to 255 (Stall current %)
【
#2246
】
SV046 FHz2 Notch filter frequency 2
Set the vibration frequency to suppress when machine vibration occurs.
(Normally, do not set 80 or less.)
Set to "0" when not using.
Related parameters: SV033/bit7-5, SV115
---Setting range---
0 to 2250 (Hz)
