Part 2: Review on Replacement of MR-J2S-_A_ with MR-J4-_A_
MR-J2S-_A_
No. Name and function
35 Position loop gain 2
Used to set the gain of the position loop.
Set this parameter to increase the position response to
level load disturbance.
Higher setting increases the response level but is liable
to generate vibration and/or noise.
When auto tuning mode 1 or 2, manual mode 1, and
interpolation mode are selected, the auto tuning result is
automatically used.
36 Speed loop gain 1
Normally, it is unnecessary to change this parameter.
Higher setting increases the response level but is liable
to generate vibration and/or noise.
When auto tuning mode 1 or 2 and manual mode 1 are
selected, the auto tuning result is automatically used.
37 Speed loop gain 2
Set this parameter when vibration occurs on machines of
low rigidity or large backlash.
Higher setting increases the response level but is liable
to generate vibration and/or noise.
When auto tuning mode 1 or 2 and interpolation mode
are selected, the auto tuning result is automatically used.
38 Speed integral compensation.
Used to set the integral time constant of the speed loop.
Decreasing the setting value will increase the response
level, but vibration and noise are generated more easily.
When auto tuning mode 1 or 2 and interpolation mode
are selected, the auto tuning result is automatically used.
39 Speed differential compensation
Used to set the differential compensation.
To enable the setting value, turn on PC (proportional
control).
Setting range: 0 to 1000
Initial
No.

48 PB10 Speed integral compensation
Used to set the integral time constant of the speed
loop.
When auto tuning mode 1 is selected, the auto
tuning result is automatically used.
980 PB11 Speed differential compensation
Used to set the differential compensation.
To enable the setting value, turn on PC (proportional
control).
Setting range: 0 to 1000
Set the same value as for MR-J2S-_A_.
