Part 4: Review on Replacement of MR-J2S-_CP_/CL_ with MR-J4-_A_-RJ
MR-J2S-_CP_ or MR-J2S-_CL_
No. Name and function
38 Speed integral compensation.
Used to set the integral time constant of the speed loop.
When auto tuning is 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
40 JOG operation acceleration/deceleration time constant
Set motor acceleration/deceleration time constant during
the JOG operation.
Setting range: 0 to 20000
41 Home position return acceleration time constant
Set the accel./decel. time constant of the time when
returning to the home position.
Setting range: 0 to 20000

No.
CP CL
48 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.
980 980 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-_CP_.
100 PC01 JOG operation acceleration time constant
Set the acceleration time constant during the
JOG operation in the program method.
Set the acceleration time required to reach the
rated speed from 0 r/min.
Speed
Rated
speed
0 r/min
For example, for a servo motor with a rated
speed of 3000 r/min, set 3000 (3 s) to increase
the speed from 0 to 1000 r/min in 1 s.
Even if the value more than 20000 ms, it will be
clamped at 20000 ms.
Setting range: 0 to 50000
PC02 JOG operation deceleration time constant
Set the deceleration time constant during the
JOG operation in the program method.
Set the deceleration time required to reach 0
r/min from the rated speed.
Even if the value more than 20000 ms, it will be
clamped at 20000 ms.
Setting range: 0 to 50000
100 PC30 Home position return acceleration time constant
Use this parameter to perform the home return in
the program method. Set the acceleration time
constant of the time when returning to the home
position. Set the acceleration time required to
reach the rated speed from 0 r/min.
Even if the value more than 20000 ms, it will be
clamped at 20000 ms.
Setting range: 0 to 50000
PC31 Home position return deceleration time constant
Use this parameter to perform the home return in
the program method. Set the deceleration time
constant of the time when returning to the home
position. Set the deceleration time required to
reach 0 r/min from the rated speed.
Even if the value more than 20000 ms, it will be
clamped at 20000 ms.
Setting range: 0 to 50000

MR-J4-_A_-RJ
Name and function
If the set speed command
is slower than the rated
speed,
acceleration/deceleration
time will be shortened.
