REPLACEMENT OF LINEAR SERVO MOTOR IN
THE ABSOLUTE POSITION DETECTION
SYSTEM
3.1
Replacement of primary side (coil) or secondary
side (magnet)
After replacing the primary side or the secondary side, carry out the magnetic pole detection again.
3.2

Replacement of linear encoder

After replacing the linear encoder, carry out the magnetic pole detection and homing.
Checking method of the mounting position of linear encoder
1.
Before replacing the linear encoder, check the encoder information using MR Configurator2, with the linear servo motor
fixed at the specified position.
2.
Replace the linear encoder with a position gap before and after the replacement at ± 0.1 mm.
3.
After replacing the linear encoder, check the encoder information using MR Configurator2, with the linear servo motor
fixed at the specified position again.
4.
Confirm that the value converted from the difference of the encoder information (resolution unit), before and after
replacement of the linear encoder, is ± 0.1 mm or less.
Reading method of encoder information by using MR Configurator2
1.
Check that the personal computer is connected with the servo amplifier, and select "Diagnosis" and then select "Linear
diagnosis". The following window appears.
2.
