SAFETY PRECAUTIONS

(Read these precautions before using this product.)
Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle
the product correctly.
The precautions given in this manual are concerned with this product only.
In this manual, the safety precautions are classified into two levels: "
WARNING
CAUTION
Under some circumstances, failure to observe the precautions given under "
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
● Configure safety circuits external to the product to ensure that the entire system operates safely even
when a fault occurs in the external power supply or the product.Failure to do so may result in an
accident due to an incorrect output or malfunction.
(1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting
operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured
external to the product.
(2) When the product detects an abnormal condition, it stops the operation and all outputs are:
• Turned off if the overcurrent or overvoltage protection of the power supply module is activated.
• Held or turned off according to the parameter setting if the self-diagnostic function of the
product detects an error such as a watchdog timer error.
● Configure a circuit so that the product is turned on first and then the external power supply. If the
external power supply is turned on first, an accident may occur due to an incorrect output or
malfunction.
● For the operating status of each station after a communication failure, refer to manuals relevant to the
network. Incorrect output or malfunction due to a communication failure may result in an accident.
● Before performing operations for the product from the peripheral connected, read the relevant
manuals carefully and ensure the safety.
[Design Precautions]
CAUTION
● Do not install the control lines or communication cables together with the main circuit lines or power
cables.Doing so may result in malfunction due to electromagnetic interference.Keep a distance of
100mm or more between those cables.
● When selecting fuses and breakers for external circuits, consider the specification values of fusing/
detection characteristics and inrush current.
● When using an uninterruptible power supply (UPS), do not use the one that outputs square waves.
