  • Page 4: Introduction

    Introduction Introduction This user manual for the DeviceNet (DFD11A) option describes how to install the DFD11A ® DeviceNet option card in the drive inverter and how to start up the MOVIDRIVE on the DeviceNet fieldbus system. As well as explaining all settings on the fieldbus interface, this document also deals with the vari- ous DeviceNet connection variants in the form of brief startup examples.
  • Page 5 Introduction Every DeviceNet option card is designed so the fieldbus-specific MAC-ID and baud rate settings are made using hardware switches on the option card. This manual setting means the drive inverter can be integrated into the DeviceNet environment and switched on within a very short period of time.

  • Page 6: Installation

    Installation Installation Supported unit types The DFD11A option for the DeviceNet connection can be operated with all drive inverters in the ® MOVIDRIVE series. Installation of the option card Before you begin: • Take suitable measures to dissipate any electrical charge in your body before you touch the option card (discharge strap, conductive shoes, etc.).

  • Page 7: Shielding And Routing Of The Bus Cables

    Installation The DeviceNet option card is opto-decoupled on the driver side in accordance with the DeviceNet specification (Volume I, Chapter 9). This means the CAN bus driver must be powered with 24 V via the bus cable. The required cable is also described in the DeviceNet specification (Volume I, Appendix B). The connection must be made according to the color code specified in Table 1.

  • Page 8: Setting The Dip Switches

    Installation Setting the DIP switches There are two DIP switch blocks of 4 DIP switches each on the DFD11A DeviceNet card. Two DIP switches are used for setting the baud rate and 6 for setting the MAC-ID (Media Access Control Identifier).

These files must be installed using the DeviceNet Manager software.

  • Page 14: Process Data Exchange

    Project Planning and Startup Process data exchange 3.3.1 Polled I/O The polled I/O messages correspond to the process data messages of the SEW fieldbus profile and up to three process data words can be exchanged between the control and the inverter. The process data length can be set with MX_SHELL (version 1.30 or later) and DBG (version .13 or later) using the parameter P877 DeviceNet PD Configuration .
  • Page 15 Project Planning and Startup Project planning for three process data words The factory setting of the process data configuration is process data length = 3. This setting be altered using the DeviceNet PD Configuration parameter. In MX_SHELL or DBG, the setting is displayed via the parameter DeviceNet PD configuration = 3 PD or 3PD + Param .
  • Page 16 Project Planning and Startup Project planning for two process data words Process data length = 2 can be set using the DeviceNet PD Configuration parameter. In this case, the setting 2 PD or 2PD + Param must be selected in MX_SHELL or DBG. As a result, two process data words (4 bytes) are processed in the inverter and two process input data words are sent to the control.
  • Page 17 Project Planning and Startup Project planning for one process data word Process data length = 1 can be set using the DeviceNet PD Configuration parameter. In this case, the setting 1 PD or 1PD + Param must be selected in MX_SHELL or DBG. As a result, one process output data word (1 byte) is processed in the inverter and one process input data word is sent to the control.

  • Page 18: Bit-Strobe I/O

    Project Planning and Startup If a timeout occurs for the polled I/O messages, this connection type enters timeout status. Incom- ing polled I/O messages are no longer accepted. The timeout response triggers timeout reaction set in the inverter. The timeout response can be reset with DeviceNet by using the reset service of the connection object (class 0x05, instance 0x02, undetermined attribute), by dropping the connection, by using the reset service of the identity object (class 0x01, instance 0x01, undetermined attribute) or with the reset bit in the control word.
  • Page 19 Project Planning and Startup Each participant which has received this bit-strobe I/O message responds with its current process input data. The length of the process input data corresponds to the process data length for the polled I/O connection. It can also be set using the DeviceNet PD Configuration parameter.
