Routine Inspections
Section 13-1
9.
Download only the parameters to the MC Unit, and save them all in flash
memory.
10. Turn the PLC power OFF and back ON to start up the MC Unit with the new
parameters.
11. Download all of the programs and position data to the MC Unit, and save
them all in flash memory.
With this, the replacement of the MC Unit will be complete.
13-1-3 Precautions When Replacing a Servomotor
Adjusting the Origin
The origin search finds the mechanical origin with the encoder phase-Z posi-
tion as the reference. The phase-Z position will be changed when the Servo-
motor is replaced, so make preparations in advance by marking the
mechanical origin, and so on, so that the mechanical origin can be adjusted to
the same position after the replacement. To adjust the mechanical origin,
adjust the reference origin offset value (in the machine parameters) used in
the origin search.
Absolute Position Setting
Parameter
When an absolute Servomotor is replaced, the absolute encoder’s absolute
position for the origin will be changed and positioning will not be possible for
files with the previous system parameters. When replacing an absolute Servo-
motor, therefore, use the following procedure to reset the absolute position
parameters for each parameter file.
1,2,3...
1.
Download the pre-replacement parameters.
2.
Write the parameters to the flash memory.
3.
Reset the power supply.
4.
Move the machine to the origin position. (Refer to
SECTION 9 Establishing
the Origin
.)
5.
Set the absolute origin. (Refer to
SECTION 9 Establishing the Origin
.)
6.
Upload the parameters and save the file.
7.
If other system parameter files are also to be used, repeat the above pro-
cedure for those parameters as well.
