The INIT switch bypasses the loading of any saved configuration.  Use this switch if there are suspected configuration issues causing alarms on the controller that may prevent you from connecting to the MPiec controller.  If the INIT switch is ON and the CNFG switch is OFF, the controller will show no axes connected.

The CNFG switch automatically configures the MPiec controller with the supported devices attached to the Mechatrolink network and I/O cards.  When this switch is ON the MPiec controller can control any supported devices attached regardless if they are in a saved configuration or not.  Yaskawa recommends leaving this switch on.

The  SUP/MNT switch puts the MPiec controller in supervisor mode for firmware upgrades.  When this switch is ON, the controller will not “control” anything (The PLC will not run.)  Servos cannot be enabled and I/O cannot be read or written.

The only way to know the complete specifications of the MP3300iec CPU card is to know the part/model number of the card. The part/model number can be found on the original packaging that the card came in.

If the original packaging is not available, the part/model number can be found two ways:

     1. Scan the QR code on the MP3300iec CPU card to find the product code.
          a. The product code is used to look up the part/model number.

     2.Connect to the MP3300iec via the web browser to find the part/model number.


See the attached PDF for specifications on the part/model number. The PDF will also provide the part/model number based on the QR product code.

The MP3300iec Hardware Manual (YAI-SIA-IEC-7) can also be used to look up the specifications on the part/model number.

If the controller had any problems discovering the ServoPacks when powering up, the ServoPacks may have to be power cycled.  The first remedy to try is power cycle the entire system.  For the axes to be displayed as online, they must have been powered up before the MWiec controller.  Since the controller takes several seconds to complete its power up phase, powering the entire system at the same time is fine.

If there is no Startup configuration, or if any of the hardware may have been changed, check the switch settings for all ServoPacks.  All Mechatrolink III devices must be configured for 48 byte packets and the assigned node numbers must be unique and in the range of 3 to 64.

Next, confirm that all cables are connected correctly.  The MP3000iec controllers and ServoPacks have LEDs in the Mechatrolink connector that are lit when a cable is plugged into the socket that is connected to an active node. When all devices are powered, check the LED status in all connectors.

Finally, if there is a Startup configuration and all the hardware is configured correctly, check the configured response times.  The configured response times must be very close to the measured response times.  Values that are slightly lower, or much higher than the measured response times may cause the controller not to connect to these nodes.  The measured response times can be viewed by allowing doing the following:

1)      Using the web server, delete the Startup Configuration

2)      Set the MWiec controller to self configure (CNFG DIP switch must be ON)

3)      Using the Hardware Configuration, connect with a new project, or connect with an existing project and use the discovered configuration.

4)      Refer to the Mechatrolink-III node in the Hardware Configuration to view the measured response times.
