SAFETY PRECAUTIONS
(Read these precautions before using.)
When using Mitsubishi equipment, thoroughly read this manual and the
associated manuals introduced in the manual. Also pay careful attention to safety
and handle the module properly.
These precautions apply only to Mitsubishi equipment. Refer to the CPU module
user's manual for a description of the programmable controller system safety
precautions.
In this manual, the safety precautions are classified into two levels:
" WARNING" and " CAUTION".
Under some circumstances, failure to observe the precautions given under
" CAUTION" may lead to serious consequences.
Observe the precautions of both levels because they are important for personal
and system safety.
Make sure that the end users read this manual and then keep the manual in a safe
place for future reference.
[Design Precautions]
WARNING
● Install a safety circuit external to the programmable controller that keeps the
entire system safe even when there are problems with the external power
supply or the programmable controller main module.
An accident may occur by a false output or a malfunction.
1) Configure interlock circuits such as an emergency stop circuit and
high/low limits of positioning to prevent damages to the equipment.
Configure these circuits outside of the programmable controller.
2) The zero return action is controlled by two kinds of data: the zero return
direction and zero return speed. Since the system keeps operating
without decelerating if a wrong zero return direction is set, apply damage
prevention measures to the equipment.
WARNING
Indicates that incorrect handling may cause
hazardous conditions, resulting in death or severe
injury.
Indicates that incorrect handling may cause
hazardous conditions, resulting in minor or moderate
injury or property damage.
