SV038 FHz1
Notch filter
frequency 1
Set the vibration frequency to suppress if machine vibration occurs.
(Valid at 36 or more) When not using, set to "0".
0 to 4500

SV039 LMCD
Lost motion
compensation timing
Set this when the lost motion compensation timing doest not match.
Adjust by increasing the value by 10 at a time.
0 to 2000
(ms)
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, the actual value that is set is 2m. Adjust by increasing by
1m at a time.
0 to 100
(m)
SV041 LMC2
Lost motion
compensation 2
Set this with SV016 (LMC1) only when you wish to set the lost motion
compensation amount to be different depending on the command directions.
Set to "0" as a standard.
-1 to 200
(Stall
current %)
SV042 OVS2
Overshooting
compensation 2
Set this with SV031 (OVS1) only when you wish to set the overshooting
compensation amount to be different depending on the command directions.
Set to “0” as a standard.
-1 to 100
(Stall
current %)
SV043 OBS1
Disturbance
observer filter
frequency
Set the disturbance observer filter band.
Set to "100" as a standard.
To use the disturbance observer, also set SV037 (JL) and SV044 (OBS2).
When not using, set to "0".
0 to 1000
(rad/s)
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 not using, set to "0".
0 to 500

SV045 TRUB
Current
compensation
(the high order 8 bits)
Set "0" for the low order 8 bits.
Current bias:Use the high order 8 bits.(IB1)
Use this in combination with SV030 and the high order 8bits of SV040.

SV046 FHz2
Notch filter
frequency 2
Set the vibration frequency to suppress if machine vibration occurs.
(Valid at 36 or more) When not using, set to "0".
0 to 4500
(Hz)
SV047 EC
Inductive voltage
compensation gain
Set the inductive voltage compensation gain. Set to "100" as a standard.
If the current FB peak exceeds the current command peak, lower the gain.
0 to 200
(%)
SV048 EMGrt
Vertical axis drop
prevention time
Input a length of time to prevent the vertical axis from dropping by delaying
Ready OFF until the brake works when the emergency stop occurs.
Increase the setting by 100msec at a time and set the value where the axis
does not drop.
0 to 20000
(ms)
SV049 PGN1sp
Position loop gain 1
in spindle
synchronous control
Set the position loop gain during the spindle synchronous control
(synchronous tapping, synchronous control with spindle/C axis).
Set the same value as the value of the spindle parameter, position loop gain
in synchronous control.
When performing the SHG control, set this with SV050 (PGN2sp) and
SV058 (SHGCsp).
1 to 200
(rad/s)
SV050 PGN2sp
Position loop gain 2
in spindle
synchronous control
Set this with SV049 (PGN1sp) and SV058 (SHGCsp) if you wish to perform
the SHG control in the spindle synchronous control (synchronous tapping,
synchronous control with spindle/C axis).
When not performing the SHG control, set to "0".
0 to 999
(rad/s)
SV051 DFBT
Dual feed back
control time constant
Set the control time constant in dual feed back.
When “0” is set, the actual value that is set is 1ms.
The higher the time constant is, the closer it gets to the semi-closed control,
so the limit of the position loop gain is raised.
0 to 9999
(ms)
SV052 DFBN
Dual feedback
control dead zone
Set the dead zone in the dual feedback control.
Set to “0” as a standard.
0 to 9999
(µm)
SV053 OD3
Excessive error
detection width in
special control
Set the excessive error detection width when servo ON in a special control
(initial absolute position setting, stopper control, etc.).
If "0" is set, excessive error detection won’t be performed.
0 to 32767
(mm)
SV054 ORE
Overrun detection
width in closed loop
control
Set the overrun detection width in the full-closed loop control.
If the gap between the motor side detector and the linear scale (machine
side detector) exceeds the value set by this parameter, it is judged to be
overrun and Alarm 43 will be detected.
When “-1” is set, the alarm detection won’t be performed. When “0” is set,
overrun is detected with a 2mm width.
-1 to 32767

SV055 EMGx
Max. gate off delay
time after
emergency stop
Set the time from when emergency stop is input to when READY is forcibly
turned OFF.
Normally, set the same value as SV056.
When using vertical axis drop prevention control, the gate off will be delayed
by the time set in SV048 even if SV055 is smaller than SV048.
