(5) Magnetic pole detection at the replacement of servo amplifier
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 Configurator.
(a) Procedures
1) Read the magnetic pole information of the servo amplifier before the replacement.
2) Write the read magnetic pole information to the servo amplifier after the replacement.
3) Perform the test operation with the torque limit for ensuring the safety, and confirm that there is no
trouble.
(b) Transplant method of the magnetic pole information
1) How to read the magnetic pole information from the servo amplifier before the replacement
a) Select "MR-J3-B Linear" from the system setting of MR Configurator.
b) Confirm that the personal computer is connected to the servo amplifier, and select "Diagnostic"
and then "Linear diagnostic".
c) Click the "Magnetic pole information" button ( 1) in Figure) to open the magnetic pole information
window.
d) Click "Read All" of the magnetic pole information window. ( 2) in Figure)
e) Confirm the data 1 and data 2 ( 3) in Figure) of the magnetic pole information window and take
notes.
2) How to write the magnetic pole information to the servo amplifier after the replacement
a) Select "MR-J3-B Linear" from the system setting of MR Configurator.
b) Confirm that the personal computer is connected to the servo amplifier, and select "Diagnostic"
and then "Linear diagnostic".
c) Click the "Magnetic pole information" button ( 1) in Figure) to open the magnetic pole information
window.
d) 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.
e) Click "Write All" ( 4) in Figure) of the magnetic pole information window.
f) Turn the power of servo amplifier off once, and then turn it on again.
