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
7 Position loop gain 1
Used to set the gain of the position loop 1.
Increase the gain to improve track ability in response to
the position command.
8 Home position return type
Set home position return types, home position return
direction, and proximity dog input polarity.
0
Home position return types
0: Dog type
1: Count type
2: Data set type
3: Stopper type
4: Home position ignorance (servo-on position as
home position)
5: Dog type rear end reference
6: Count type front end reference
7: Dog cradle type
Home position return direction
0: Address increasing direction
1: Address decreasing direction
Proximity dog input polarity
0: Detect the dog by opening between DOG and
SG
1: Detect the dog by shorting between DOG and
SG
9 Home position return speed
Set the servo motor speed when returning to the home
position.
10 Creep speed
Set the creep speed after the proximity dog is detected.
11 Home position shift distance
Set the shift travel distance from the detected position of
Z-phase pulse in the encoder.
12 Rough match output range
Set the range of remaining distance of the command
outputting rough match (CPO).
13 JOG speed
Set the JOG speed command.
14 S-pattern acceleration/deceleration time constant
Set when inserting an S-pattern
acceleration/deceleration time constant for the
acceleration/deceleration time constant in the point
table.
This time constant is disabled when returning to the
home position.
15 Station number setting
Specify the station No. of the multi-dropped
communication.
Always set one station to one axis of the servo amplifier.
Setting one station number to two or more stations will
disable a normal communication.
Initial value
No.
CP CL
35 35 PB07 Model loop gain
Used to adjust the response gain till the set
position.
When auto tuning 1 is selected, the auto tuning
result is automatically used for this parameter.

Set the JOG speed.
0 0 PC03 S-pattern acceleration/deceleration time constant
This is used to smooth start/stop of the servo
motor.
Set the time of the arc part for S-pattern
acceleration/deceleration.
Set the same value as for MR-J2S-_CP_.
0 0 PC20 Station number setting
Used to set the station No. of the servo amplifier.
Setting range: 0 to 31
