13-1-1 Handling Precautions
• Turn OFF the power before replacing the Unit.
• If a Unit is found to be faulty and is replaced, check the new Unit again to
ensure there are no errors.
• When returning a faulty Unit for repair, make a detailed record of the
Unit’s malfunction and take it together with the Unit to your nearest
OMRON office or sales representative.
• If a contact is not good, put some industrial alcohol on a clean cotton cloth
and wipe the surface. After doing this, install the Unit.
• Before restarting operation, transfer the required programs, position data,
and system parameters to the MC Unit that was changed, and save them
to the flash memory.
13-1-2 Procedure for Replacing an MC Unit
Use the following procedure when it is necessary to replace an MC Unit.
1,2,3...
1.
Make a note of the unit number of the MC Unit to be replaced.
2.
To retain the status and settings of the MC Unit that is to be replaced, use
CX-Motion to upload the programs, position data, and system parameters.
3.
Turn OFF the power supply.
4.
To facilitate rewiring, carefully label the cables that are to be disconnected.
This is important, because the MC Unit has a number of connecting cables
from the Servo Driver, and unexpected operation may result if they are in-
correctly connected to the replacement Unit.
5.
Replace the MC Unit, and reconnect the wiring as before.
6.
Set the unit number for the MC Unit.
7.
Turn ON the power supply to the PLC.
8.
Clear all the programs in the MC Unit.
Installation and
wiring
Is the MC Unit securely mounted?
There must be no looseness.
With a Phillips screwdriver,
tighten all mounting screws.
Are the cable connectors properly
inserted and locked?
Carefully insert and lock all
cable connectors.
Are there any loose screws in the
external wiring?
With a Phillips screwdriver,
tighten all screws in the
external wiring.
Are any crimp terminals for external
wiring too close together?
There must be sufficient
distance between them.
Do a visual check and
separate the terminals as
required.
Are any external cables disconnected?
There must be no external
abnormalities.
Do a visual check and
connect or replace cables as
required.
