• When the ring disconnection status occurs and then you reconnect an EtherCAT communications
cable, turn OFF the power supply to the EtherCA
T master and to the slaves. Connecting a faulty
EtherCAT communications cable while the devices are in operation may stop the entire EtherCAT
communications system.
Maintenance and Inspection
• The capacitor service life is influenced by the ambient temperature. Refer to “Smoothing Capacitor
Life Curve” described in the manual. When a capacitor reaches the end of its service life and does
not work as the product, you need to replace the capacitor
