OPERATION ADJUSTMENT
7.1

Preparation for Operation

Preliminary inspection

Incorrect connection of the power supply terminal, contact of the DC input wire and power supply wire, or short-circuiting of
output wires may result in serious damage.
Before applying power, check that the power supply and ground terminals are connected correctly and input/output devices
are wired properly.
Dielectric withstand voltage test and insulation resistance test
The dielectric withstand voltage and insulation resistance test of the PLC should be measured in accordance with the
following procedure.
1.
Remove all input/output wires and power supply wires from the PLC.
2.
Connect a crossing wire to each of the PLC terminals (power supply terminal, input terminals and output terminals)
except the ground terminal. For the dielectric withstand voltage test of each terminal, refer to the general specifications
for the product (refer to Page 30 Generic Specifications).
3.
Measure the dielectric withstand voltage and insulation resistance between each terminal and the ground terminal.
• Dielectric withstand voltage
• Insulation resistance

Procedure until operation

The procedure until operation is explained below.
1.
Turn on the power of the system.
Check the following items before turning on the power of the system. When the CPU module with the factory default setting is
powered on, the ERR LED flashes because the module has no programs.
• The power connector is connected correctly.
• The power supply voltage is within the specified range.
• The CPU module is in the stopped status.
2.
Connection with a personal computer
Connect the CPU module with a personal computer on which an engineering tool has been installed. (Page 133
Connection with a personal computer)
3.
Format the CPU built-in memory.
Format the CPU built-in memory using the engineering tool. (GX Works3 Operating Manual)
4.
Parameter setting
Set the parameters needed for startup.
(GX Works3 Operating Manual)
• System parameters
• CPU parameters
• Module parameters
5.
Programming
Create a program using the engineering tool. (MELSEC iQ-F FX5 User's Manual (Application))
6.
Write the parameters and the program.
Write the parameters and the program set with the engineering tool into the CPU module.
