How to replace servo amplifier without magnetic pole detection

When replacing the servo amplifier, carry out the magnetic pole detection again. If the magnetic pole detection cannot be
performed, write the magnetic pole information from the servo amplifier before replacement to the one after replacement by
using MR Configurator2.
Procedure
1.
Read the magnetic pole information of the servo amplifier before replacement.
2.
Write the read magnetic pole information to the servo amplifier after replacement.
3.
To ensure safety, perform the test operation with the torque limited and confirm that the servo motor can be operated
safely.
