Preparation for Operation
Follow the steps listed below when setting up a CPM2A system.
1, 2, 3...
1. System Design
•
Select a CPM2A CPU Unit, Expansion Units and Expansion I/O Units with
the specifications required in the controlled system.
•
Design external fail-safe circuits such as interlock circuits and limit circuits.
Refer to
2-1 Specifications
and
3-1 Design Precautions
for details.
2. Installation
•
Install the CPU Unit. (Surface-mount or DIN-track installation)
•
Install the Expansion Unit(s) and Expansion I/O Unit(s).
Refer to
3-3 Installing the CPM2A
and
3-4 Wiring and Connections
for de-
tails.
3. Wiring
•
Wire the power supply and I/O devices.
•
Connect communications devices if necessary.
•
Connect the Programming Console.
Refer to
3-4 Wiring and Connections
for details.
