EtherCAT Communication Card: CMM-EC02/ CMM-EC03
CMM-EC02/ CMM-EC03 Operation Manual
2.3 Network Connection
Pay attention to the connection method for EtherCAT because its packet delivery is directional. When
front-mounting the communication card, the delivery direction for CMM-EC02/ CMM-EC03 is from left
(IN) to right (OUT). The diagram below shows the correct wiring for front-mounting CMM-EC02/ CMM-
EC03.
After finishing assembling the hardware, supply power to the drive. Then, Pr.09-60 on the drive
should display “EtherCAT”, with a current value of 6. If not, make sure your version of the drive is
correct and verify if the communication card is correctly connected.
2.4 MH300 / MS300 Drive Settings
When you operate MH300 / MS300 through CMM-EC02/ CMM-EC03, you must set the communication
card as the source of controls and settings for MH300 / MS300. Use the keypad to configure the
following parameter addresses to the corresponding values:
2.5 ESI (EtherCAT Slave Information)
To make PLC or the host controller identify MH300 / MS300, you must load the product description file
(ESI file). Download the description files from Delta’s download center.
