  • Page 15: Safety Precautions

    Safety Precautions Safety Precautions Definition of Precautionary Information The following notation is used in this manual to provide precautions required to ensure safe usage of the CK3M-series Programmable Multi-Axis Controller. The safety precautions that are provided are extremely important for safety. Always read and heed the information provided in all safety precautions.
  • Page 16: Warning

    Safety Precautions WARNING WARNING Wiring Connect this Controller correctly to the servo amplifier, encoder, and limit sensors ac- cording to the instructions in this manual. Not doing so may cause the motor to run away, resulting in serious accidents. For the Power Supply Unit or any other power supply connected to peripheral devices, connect the 0-V side to ground, or do not ground them at all.
  • Page 17 Safety Precautions The UPS used enables normal operation to continue for a certain period of time if a momentary power interruption occurs. This means that the CK3M-series Controller may receive incorrect signals from external devices that are also affected by the power interruption.
  • Page 18: Cautions

    Safety Precautions Actual Operation Check the user program, servo algorithm, data, and parameter settings for proper exe- cution before you use them for actual operation. Cautions Caution Design To control the motor safely and correctly, the servo algorithm design and gain setting work must be performed by engineers who understand control theories and the specifi- cations of this product.
  • Page 19: Precautions For Safe Use

    Precautions for Safe Use Precautions for Safe Use Transporting • Do not drop any Unit or subject it to abnormal vibration or shock. Doing so may result in Unit mal- function or burning. Mounting • Be sure that the terminal blocks, connectors, and other items with locking devices are correctly locked into place before use.
  • Page 20 Precautions for Safe Use When cross-wiring terminals, the total current for all the terminals will flow in the wire. When wiring cross-overs, make sure that the current capacity of each of the wires is not exceeded. • Do not allow wire clippings, shavings, or other foreign material to enter the Controller. Otherwise, Controller burning, failure, or malfunctions may occur.
  • Page 21 Precautions for Safe Use Turning OFF the Power Supply • Do not turn OFF the power supply or remove the USB memory device while the Controller is ac- cessing the USB memory device. Data may become corrupted, and the Controller will not operate correctly if it uses corrupted data.
  • Page 22 Precautions for Safe Use • EtherCAT communications are not always established immediately after the power supply is turned ON. Use the system-defined variables and the EtherCAT Coupler Unit device variables in the user program to confirm that I/O data communications are established before attempting control opera- tions.
  • Page 23 Precautions for Safe Use • Do not use corrosive chemicals to clean the Controller. Doing so may result in a failure or malfunc- tion of the Controller. • Dispose of the product according to local ordinances as they apply. CK3M-series Programmable Multi-Axis Controller User's Manual Hardware (O036)
  • Page 24: Precautions For Correct Use

    Precautions for Correct Use Precautions for Correct Use Storage and Installation • Follow the instructions in this manual to correctly perform installation. • Do not operate or store the Controller in the following locations. Doing so may result in burning, in operation stopping, or in malfunction.
  • Page 25 Precautions for Correct Use EtherCAT Communications • Set the Servo Drives to stop operation if an error occurs in EtherCAT communications between the Controller and a Servo Drive. • Always use the specified EtherCAT slave cables. If you use any other cable, the EtherCAT master or the EtherCAT slaves may detect an error and one of the following may occur.
  • Page 26: Regulations And Standards

    Concepts  EMC Directives OMRON devices that comply with EU Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards.*1 Whether the products conform to the standards in the system used by the customer, however, must be checked by the customer.
  • Page 27: Condition For Compliance With Eu Directives

    Regulations and Standards Condition for Compliance with EU Directives The immunity test condition for the CK3M-series Analog Input Units is as shown below. Unit type Overall accuracy Analog Input Unit +6%/-6% To connect an Analog Input Unit, use 2-core twisted-pair shielded wire. Note that compliance was con- firmed with the shielded wire grounded at both ends.
  • Page 28: Versions

    Versions Versions PMAC firmware revisions are used to manage the motion control firmware in CK3M-series CPU Units. The PMAC firmware revision is updated each time there is a change in motion control firmware. Even when two CPU Units have the same model number, they will have functional or performance differen- ces if they have different PMAC firmware revisions.

    5 Wiring Analog Input Unit Wiring This section describes the wiring for the analog input connection terminal block. 5-5-1 Wiring the Terminals Applicable Wires The wires that you can connect to the terminal block are twisted wires, solid wires, and ferrules that are attached to the twisted wires.
  • Page 175 5 Wiring Connecting Ferrules Insert the ferrule straight into the terminal hole. It is not necessary to press a flat-blade screwdriver against the release button. Ferrule After you make a connection, make sure that the ferrule is securely connected to the terminal block. Connecting Twisted Wires/Solid Wires Use the following procedure to connect the twisted wires or solid wires to the terminal block.
  • Page 176 5 Wiring After you make a connection, make sure that the twisted wire or the solid wire is securely connected to the terminal block. Precautions for Safe Use • Make sure that all wiring is correct. • Do not bend the cable forcibly. Doing so may break the cables. Removing Wires Use the following procedure to remove the wires from the terminal block.
  • Page 177 5 Wiring Installing a Terminal Block Insert the terminal block into the main body, and press hard to click the terminal block into place on the Unit. After you mount the terminal block, make sure that it is fixed to the Unit. Removing a Terminal Block Drop the lock levers on both sides of the terminal block at the same time to remove the terminal block.
