Page 18: Warning
Safety Precautions WARNING WARNING During Power Supply Do not touch any of the terminals or terminal blocks while the power is being supplied. Doing so may result in electric shock. Do not attempt to take any Unit apart. In particular, high-voltage parts are present in the Power Supply Unit while power is supplied or immediately after power is turned OFF.
Page 19 Safety Precautions Unintended outputs may occur when an error occurs in variable memory. As a counter- measure for such problems, external safety measures must be provided to ensure safe operation of the system. Provide measures in the communications system and user program to ensure safety in the overall system even if errors or malfunctions occur in data link communications or remote I/O communications.
Page 20: Cautions
Safety Precautions Cautions Caution Application Do not touch any Unit when power is being supplied or immediately after the power supply is turned OFF. Doing so may result in burn injury. Wiring Be sure that all terminal screws and cable connector screws are tightened to the tor- que specified in the relevant manuals.
Page 21 Safety Precautions If the cable redundancy function is enabled, always write a program to confirm that the network is in the cable redundancy status. If the program is not written, you cannot check that the network is not in the cable redundancy status due to a disconnection on the ring topology.
Page 22: Precautions For Safe Use
Precautions for Safe Use Precautions for Safe Use Transporting and Disassembly • Do not attempt to disassemble, repair, or modify any Units. Doing so may result in malfunction or fire. • Do not drop any Unit or subject it to abnormal vibration or shock. Doing so may result in Unit mal- function or burning.
Page 23 Precautions for Safe Use Restricted region (shaded portion) • The End Cover has a metal portion and is heavier than it looks. Be careful not to drop it when han- dling. Installation • Always connect to a ground of 100 Ω or less when installing the Units. Wiring •...
Page 24 Precautions for Safe Use Terminal Terminal block block • The angle at which you insert a screwdriver in the release holes on the screwless clamping terminal blocks of the CPU Unit is different from that on the screwless clamping terminal blocks of NX Units. Check the wiring method for the NX Unit and perform wiring correctly.
Page 25 Precautions for Safe Use because the output terminals on Output Units may momentarily turn ON when power supply is turned ON to the Controller. • If you transfer data from a backup file on an SD Memory Card to the Controller when the power sup- ply is turned ON, properly select the data groups to transfer.
Page 26 Precautions for Safe Use a) Changing the operating mode of the CPU Unit (including changing the setting of the Startup Mode) b) Changing the user program or settings c) Changing set values or present values d) Forced refreshing e) Starting the CPU Unit with the battery exhausted f) Restarting a slave or Unit after you change any settings g) Transferring a backup file on the SD Memory Card •...
Page 27 Precautions for Safe Use Depending on the difference in the forced status, the control system may operate unexpectedly. • Do not specify the same address for the AT specification for more than one variable. Doing so would allow the same entity to be accessed with different variable names, which would make the user program more difficult to understand and possibly cause programming mistakes.
Page 28 Precautions for Safe Use • If the Fail-soft Operation Setting is set to Stop, process data communications will stop for all slaves when an EtherCAT communications error is detected in a slave. At that time, the Servo Drive will operate according to the Servo Drive specifications. Make sure that the Fail-soft Operation setting results in safe operation when a device error occurs.
Page 29 Precautions for Safe Use the ring topology, the transmission delay time is increased and the task execution time may be lon- ger. Version Information The cable redundancy function can be used with project unit version 1.40 or later. Motion control •...
Page 30 Precautions for Safe Use FirstOnPosition LastOnPosition OffCompensation LastOnPosition after compensation • Use the NX_AryDOutTimeStamp (Write Digital Output Array with Specified Time Stamp) instruction only after you confirm that InOperation from the MC_DigitalCamSwitch (Enable Digital Cam Switch) instruction is TRUE. • If you change the unit conversion settings, perform homing again. If you do not perform homing, un- intended operation of the controlled system may occur.
Page 31 Precautions for Safe Use • Apply power for at least five minutes before changing the Battery. Install a new Battery within five minutes (at 25°C) of turning OFF the power supply. If power is not supplied for at least 5 minutes, the retained clock data may be initialized.
