[Default value]
Description
Fd-14
Notch filter 2
frequency
3.0 to 1000.0
(Hz)
[Depends on model]
Sets the resonance frequency of notch filter 1.
(Use TOP software to set this parameter.)
Fd-15
Notch filter 2
bandwidth
0 to 40
(dB)
[Depends on model]
Set the bandwidth of notch filter 2 at the resonance
frequency.
(Use TOP software to set this parameter.)
Fd-20
Speed command
filter time constant
0 to 60000
(ms)
[Depends on model]
Sets the time constant for the first-order lag filter
to apply to the speed command value. When this
parameter is set to 0, no filtering is performed.
Fd-30
Gain change
mode
non
AUto
GCH
[Depends on model]
Sets the switching function in gain switch mode. Do
not set this parameter to "GCH".
Setting Description
non Gain does not change.
AUto Gain changes automatically.
Fd-31
Position error
width for gain
change
0 to 65535
[pulses]
[Depends on model]
Sets the threshold value of the position error width
(difference between position command value and
position detection value) used to start automatic
gain change (Fd-30: AUto) in position control mode.
Set this parameter in units of the number of position
sensor pulses.
Fd-32
Second position
control cut-off
frequency
0.01 to 99.99
(Hz)
[Depends on model]
Sets the second position control cut-off frequency to
perform gain change in position control mode.

Fd-33
Position gain
change time
constant
0.0 to 500.0
(ms)
[Depends on model]
Sets the gain change time constant to perform
gain change in position control mode. When this
parameter is set to 0, the gain changes immediately.
Fd-36
Position command
filter time constant
0 to 60000
(ms)
[Depends on model]
Sets the time constant for the first-order lag filter
to apply to a position command value. When this
parameter is set to 0, no filtering is performed.
Always set to 0 when performing -one-way
continuous operation or one-way synchronous
conveyor operation in position control mode. If not
set to 0, a position error fault (E83) will occur.
Fd-40
Fast positioning
mode
non
FASt
FoL
[Depends on model]
Sets the fast positioning mode to perform fast
positioning in position control mode. When setting
this parameter to "FASt" or "FoL", set the Moment
of inertia (Fd-00) correctly.
Setting Description
non Performs normal position control
FASt Shortens the positioning settling time.
FoL
Performs minimum position error control.
Fd-41
Position feed
forward filter time
constant
0.00 to 500.00
(ms)
[Depends on model]
Sets the time constant for the first-order lag filter
used for position feed forward compensation in
position control. When this parameter is set to 0, no
filtering is performed.
Fd-42
Position error
filter gain
0 to 100
(%)
[Depends on model]
Use this parameter to adjust the amount of position
error which may occur during "minimum position
error control" in position control mode.
Fd-44
(Note 1)
Speed feedback
filter time constant
0.00 to 500.00
(ms)
[Depends on model]
Set the time constant for the first-order lag filter
used for speed detection values.
When this parameter is set to 0, no filtering is
performed.
