• Set the notch frequency to match the
response frequency of the mechanical
system.
0: Deep (-40db)
1:
(-14db)
2:
(-8db)
3: Shallow (-4db)

Feed forward
gain
• Set the feed forward gain for position
control. Set "100" to nearly zero the
droop pulse value when operation is
performed at constant speed. Note the
rapid acceleration/deceleration time will
increase overshoot.
(Acceleration/deceleration time set in
100 [%] is about 1[s] or more.
POINT
Be sure to set up this parameter "2:
Invalid (Automatic tuning invalid)"
when you set "Automatic tuning".
0 to 100[%]
6.3.6
9
In-position
range
• Set the droop pulse in the deviation
counter of the servo amplifier.
POINT
In the MR-J2S-B only, set "Feed back
pulse" in the feed back pulse unit.
0 to 32767[PLS]

sequence
output
• Set a time delay from when the
electromagnetic brake interlock
signal (MBR) turns off until the base
circuit is shut off.
0 to 1000[ms]

(Note-1) : Only MR-J2S-B is set with the adjustment parameter 2.
