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.
