00:00:00 Yaskawa Welcome to this Yaskawa eLearning video. I'm Paul Avery This presentation is part of a series of videos demonstrating the ease of integrating Yaskawa variable frequency drives, or VFDs, onto a Rockwell Automation PLC, using the Rockwell software. This presentation will cover how to connect a Yaskawa VFD to a typical Rockwell Automation PLC. In our case we'll be using a Rockwell Automation CompactLogix PLC

00:00:37 but the same steps will apply if you have a ControlLogic PLC. In this video we will cover What hardware and software is required, How to configure the VFD to connect to be controlled by the Rockwell PLC, How to add our VFD as a node on the Ethernet/IP network, and How to download the configuration to the PLC and check that there are no errors. Our three main hardware components necessary for this demonstration will be the Yaskawa A1000 VFD, our laptop with Logix designer, previously RSLogix 5000 and the Rockwell PLC.

00:01:18 First thing we'll need to do is make sure that the VFD and PLC are connected on the same network This could mean a direct connection between the VFD and plc, via the same switch or a series of switches connectedto each other Now let's get the device is powered out Now that the devices are powered up the first thing you need to do with the VFD is to program its network settings. Per ODVA the default mode of the drives to use DHCP to get its network settings. If you're not using DHCP then you'll need to program the settings by hand. Using the keypad or drive wizard software set the option card's IP address,

00:01:58 which we'll set to 192.168.1.20 for this demonstration. Repeat the steps for the subnet mask and gateway if needed. Lastly, to make sure we get the program type IP we set, change parameter F7 - 13 to 0 and then cycle power to the VFD To confirm our addresses have taken, we can use monitor U6-80 through U6-91 to check the values. These values will show as long as the option card is connected to another device via ethernet cable which in our case is the PLC. Also the network status LED and the optioncard should now glow a steady green. One last thing before we move on to the PLC, if you plan and controlling the VFD using the PLC vs monitoring only you will need to configure the A1000 to look

00:02:52 for the Run and Reference commands from the Ethernet/IP option board. To do this we will need to set parameters b1-01 and b1-02 to a setting of 3, which is option printed circuit board. There is no need to cycle power to the VFD after this adjustment. Now let's move on to configuring the PLC so that it can start communicating to the VFD. To do this will need to use our Logix designer software. We're going to assume that you have a project started and that your PLC is configured minus the VFD. Find the ethernet icon under the controller organizer on the left side. Right click on that icon and select new module. It will bring up a list of devices that can be added to the PLC.

00:03:40 If we wished, we could import the EDS files for our A1000 and then our A1000 would be included on the list of things to add to the PLC Rather we will add our VFD to the network as a generic ethernet module That way if later we want to replace the VFD with a different size or different generation of drive we will not have to change anything provided we use the same IP address and assemblies. Once we select genetic ethernet module a new module properties window will pop up. There are seven steps to configuring the generic module. One: name your module. The name will show up on the controller navigation. Two: Change the communication format from a double integer to a single integer.

00:04:29 Three: Input the IP address of your SI-EN3 option card. In our case we program the drive to 192.168.1.20. Four: Change the input assembly to your desired assembly. Please refer to the Ethernet/IP manual for a list of available assemblies. For this demonstration we're going to use assembly 71 which is a 4-byte or two-word assembly We'll change the size of the assembly to 2 since the size adjustment is in terms of a 16-bit word and not an 8-bit byte For step five we repeat the input assembly set up except on the output assembly. For our demonstration we will use assembly 21 which has a size of two words. Step 6 is to simply set the configuration number to 1 and then click OK. The seventh and final step will involve changing the RPI or requested packet interval time.

00:05:28 It is recommended to use one hundred milliseconds to reduce the amount of processing required from the PLC. Ultimately the more often the PLC has to send and receive messages the faster it has to work but the faster something is done like stamping office paperwork the more likely it becomes an error will be made. Now that we have created our VFD as a generic ethernet module on the PLC, we will need to download this configuration to the PLC itself. If there are no errors during the download then you can put the controller into the Run mode.

00:06:04 If there are no configuration or communication errors between the PLC and VFD, the status will read I/O OK. Otherwise you'll get a yellow triangle with an exclamation point in it next to the drive and the status will read I/O not responding. Please refer to the area code generated to help troubleshoot this situation I hope you enjoyed this e-Learning video.
