0000h PB13 Machine resonance suppression filter 1
Used to set the notch frequency of machine resonance
suppression filter 1.
When "Automatic setting (_ _ _ 1)" is selected in "Filter
tuning mode selection" of [Pr. PB01], the adjustment
result is reflected.
When "Manual setting (_ _ _ 2)" is selected in "Filter
tuning mode selection" of [Pr. PB01], this setting value is
enabled.

result is reflected.
Set manually for the manual setting.

19 Feed forward gain
Set the feed forward gain.
When the setting is 100%, the droop pulses during operation
at constant speed are nearly zero. However, sudden
acceleration/deceleration will increase the overshoot. As a
standard, when setting the feed forward gain as 100%, set 1
s or more as the acceleration/deceleration time constant up
to the rated speed.
0 PB04 Feed forward gain
Set the feed forward gain.
If 100% is set and constant-speed operation is
implemented, pulse droop will be almost zero. However,
sudden acceleration/deceleration will increase the
overshoot. As a standard, when setting the feed forward
gain as 100%, set 1 s or more as the acceleration time
constant up to the rated speed.

20 In-position range
Set the range of droop pulses occurred when outputting INP
(positioning completion) to a controller. Set by the feedback
pulse unit ([Pr. 6]).
For example, when wanting to set ±10
μ m in a state of direct
connection to the ball screw, a lead wire length of 10 mm,
and a feedback pulse 8192 pulses/rev ([Pr. 6]: 1), set "8", as
shown in the equation below.
100 PA10 In-position range
Used to set an in-position range per command pulse unit.
