Wiring When Using the Selective Extended Joint Function

The following figure shows the wiring diagram for two robots cooperation.
For the wiring diagram for three or more robots cooperation, refer to the linked page.

HUB

The communication speed must be 1 Gbps or higher.

If devices other than WINCAPSIII (PC) are connected to the HUB, confirm that the cooperative control function is not affected by the devices by using actual robots.

In particular, do not connect a device with a lot of traffic (example: camera) if possible because the robot may stop due to an error depending on the operation condition.

Ethernet communication LAN cable

Use a shielded LAN cable of category 6 or higher.

Either a straight- or a cross-LAN cable can be used.

EtherCAT communication LAN cable

Use a twisted pair LAN cable of category 5 or higher.

Either a straight- or a cross-LAN cable can be used.

  • An EtherCAT master board and an EtherCAT slave board have two LAN cable connectors. Be sure to connect cables to the connectors shown in the figure above.
  • Be sure to wire a device connected to the EtherCAT master board to the EtherCAT slave board. If selective extended joints and the EtherCAT master board are connected and the EtherCAT slave board is connected from the selective extended joints, the robot does not work properly.
  • For status information about EtherCAT master board and EtherCAT slave board, refer to [LED Display] of the master board and [LED Display] of the slave board.
Option part
EtherCAT master board

A master controller requires an EtherCAT master board and two of software licenses; one is for the cooperative control function (for the master controller) and the other is for the selective extended joint.

However, depending on your controller's configuration, you do not need to purchase some of them. For example, to add a cooperative control function into a robot controller that already has the selective extended joint function, you only have to purchase a software license for the cooperative control function (for the master controller).

The part numbers are shown in the tables below. Select and place an order a product according to your usage.

  • If your robot controller requires software licenses for both the cooperative control function (for the master controller) and the selective extended joint, select part number from the table below.

For selective extended joint, the multi-axis servo amplifier is not supported.

 
Maximum number of selective extended joints that can be connected
The maximum number of selective extended joints that can be connected per robot controller is predetermined.
It is four when a four-axis robot is connected or two when a six-axis robot is connected to a robot controller.
For example, when two robots are used for cooperation, if both the master controller and the slave controller are connected to a four-axis robot for each, a total of eight selective extended joints can be connected.

Whether selective extended joints are allocated to the master or slave controller is determined based on the connection order. For details, refer to "Connection Configuration of Selective Extended Joints".

Wiring when sending/receiving data with WINCAPSIII and robot controllers When the system for the cooperative control function is adjusted, data is sent/received between WINCAPSIII and a master controller, and also between WINCAPSIII and a slave controller as well. In this case, a PC with WINCAPSIII installed and the master and slave controllers must be all connected. Therefore, wire them as shown above.
Others
  • Since an master controller equips an EtherCAT master board, the same PCI board, such as an electric gripper control board or parallel I/O board, cannot be used together. A PCI Express board, such as a CC-Link remote device board, can be used together.
  • To use an electric gripper in a robot connected to the master controller, refer to "Precautions on Using an Electric Gripper".
  • Field network is not available for the slave Controller. With WINCAPSIII, set the I/O allocation of the slave controller to "Mini I/O-dedicated mode".

Wiring Diagram for Cooperation with Three or More Robots

To cooperate with three or more robots, each robot connected to the slave controller will be given a robot name as the following figure shows.
Based on the EtherCAT connection, from the nearest to the master controller, robots are named in the order of Robot1, Robot2.
(Description about components is same as the table above.)
