3. Specifications and examples of external wiring
As for the details of the power supply wiring and input/output wiring, refer to
MELSEC iQ-F FX5U User's Manual (Hardware).
DESIGN PRECAUTIONS
Make sure to set up the following safety circuits outside the PLC to ensure safe
system operation even during external power supply problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
- Most importantly, set up the following: an emergency stop circuit, a
protection circuit, an interlock circuit for opposite movements (such as
normal vs. reverse rotation), and an interlock circuit (to prevent
damage to the equipment at the upper and lower positioning limits).
- Note that w hen the CPU module detects an error, such as a watchdog
timer error, during self-diagnosis, all outputs are turned off. Also, when
an error that cannot be detected by the CPU module occurs in an input/
output control block, output control may be disabled.
External circuits and mechanisms should be designed to ensure safe
machinery operation in such a case.
- Note t hat the output current of the 24 V DC service power supply varies
depending on the model and the absence/presence of extension
modules. If an overload occurs, the voltage automatically drops, inputs
in the PLC are disabled, and all outputs are turned off.
External circuits and mechanisms should be designed to ensure safe
machinery operation in such a case.
- Note that w hen an error occurs in a relay or transistor of an output
circuit, the output might stay on or off.
For output signals that may lead to serious accidents, external circuits
and mechanisms should be designed to ensure safe machinery
operation in such a case.
Construct an interlock circuit in the program s o that the whole system always
operates on the safe side before executing the control (for data change) of the
PLC in operation . Read the manual thoroughly and ensure complete s afety
before executing other controls (for program change, parameter change,
forcible output and operation status change) of the PLC in operation.
Otherwise, the machine may be damaged and accidents may o ccur due to
erroneous operations.
DESIGN PRECAUTIONS
Simultaneously turn on and off the power supplies of the CPU module and
extension modules.
WIRING PRECAUTIONS
Make sure to cut off all phases of the power supply externally before
attempting installation or wiring work.
Failure to do so may cause electric shock or damage to the product.
Make sure to attach the terminal cover, provided as an accessory, before
turning on the power or initiating operation after installation or wiring work.
Failure to do so may cause electric shock.
The temperature rating of the cable should be 80 or more.
Make sure to wire the screw terminal block in ac cordance with the
following precautions.
Failure to do so may cause electric shock, equipment failures, a shortcircuit, wire breakage, malfunctions, or damage to the product.
- The disposal size of the cable end should follow the dimensions
described in the manual.
