App. 7 How to replace servo amplifier without magnetic pole detection
CAUTION
Be sure to write the magnetic pole information of the servo amplifier before the
replacement to the servo amplifier after the replacement. If the information before
and after replacement are different, the servo motor may operate unexpectedly.
When replacing the servo amplifier, carry out the magnetic pole detection again. If the magnetic pole
detection cannot be performed unavoidably, write the magnetic pole information from the servo amplifier
before the replacement to the one after the replacement using MR Configurator2.
(1) Procedures
(a) Read the magnetic pole information of the servo amplifier before the replacement.
(b) Write the read magnetic pole information to the servo amplifier after the replacement.
(c) Perform the test operation with the torque limit for ensuring the safety, and confirm that there is no
trouble.
(2) Migration method of the magnetic pole information
(a) How to read the magnetic pole information from the servo amplifier before the replacement
1) Open the project in MR Configurator2, select "MR-J4-B" for model, and select "Linear" for
operation mode.
2) Check that the personal computer is connected with the servo amplifier, and select "Diagnosis"
and then "Linear diagnosis".
3) Click "Magnetic pole information" ( 1) in figure) to open the magnetic pole information window.
4) Click "Read All" of the magnetic pole information window. ( 2) in figure)
5) Confirm the data 1 and data 2 ( 3) in figure) of the magnetic pole information window and take
notes.
(b) How to write the magnetic pole information to the servo amplifier after the replacement
1) Open the project in MR Configurator2, select "MR-J4-B" for model, and select "Linear" for
operation mode.
2) Check that the personal computer is connected with the servo amplifier, and select "Diagnosis"
and then "Linear diagnosis".
3) Click "Magnetic pole information" ( 1) in figure) to open the magnetic pole information window.
4) Input the value of the magnetic pole information taken notes to the data 1 and data 2 ( 3) in
figure) of the magnetic pole information window.
5) Click "Write All" ( 4) in figure) of the magnetic pole information window.
6) Cycle the power of the servo amplifier.

App. 8 Two-wire type encoder cable for HG-MR/HG-KR
Use a two-wire type encoder cable for the fully closed loop control by the MR-J4-_B_ servo amplifiers.
For MR-EKCBL_M-_ encoder cables for HG-MR and HG-KR, up to 20 m cables are two-wire type. If a two-
wire type encoder cable with a length of 20 m or more is required, fabricate it using the MR-ECNM connector
set as shown in the internal wiring diagram of this section. In this case, the cable should not be longer than
50 m.
