Before installation, operation, maintenance or inspection of this product, thoroughly read through and
understand this manual and all of the associated manuals. Also, take care to handle the module properly and
safely.
This manual classifies the safety precautions into two categories:
Depending on the circumstances, procedures indicated by
It is important to follow all precautions for personal safety.
Store this manual in a safe place so that it can be taken out and read whenever necessary. Always forward it
to the end user.
1. DESIGN PRECAUTIONS
•
An AnyWireASLINK system has no control function for ensuring safety.
•
When a communication failure occurs in the network, data in the master block are held.
Check the communication status information and configure an interlock circuit in the sequence program to ensure
that the entire system will operate safely.
•
Make sure to have the following safety circuits outside of the PLC to ensure safe system operation even during
external power supply problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
1) Most importantly, have 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).
2) Note that when the PLC CPU 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 PLC CPU 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.
•
Configure safety circuits, such as an emergency stop circuit and interlock circuit, external to the AnyWireASLINK
system.
•
Install module so that excessive force will not be applied to the terminal blocks.
Failure to do so may result in wire damage/breakage or PLC failure.
•
When executing control (data changes) to an operating PLC, construct an interlock circuit in the sequence program
so that the entire system operates conservatively. Additionally, when executing control such as program changes
and operation status changes (status control) to an operating PLC, thoroughly read the manual and sufficiently
confirm safety in advance.
2. INSTALLATION PRECAUTIONS
•
Make sure to cut off all phases of the power supply externally before attempting installation work.
Failure to do so may cause electric shock.
