Page 4: Introduction
Introduction Introduction This DFC11A CAN Bus Fieldbus Interface Manual describes the procedure for installing the fieldbus ® interface in the drive inverter and for commissioning the MOVIDRIVE drive inverter when con- nected to the CAN bus. In addition to describing all the settings on the fieldbus interface, this manual further discusses the various options for connecting the drive inverter to the CAN bus in the form of commissioning examples. - Page 5 Introduction The process data and drive parameters can be sent synchronously or asynchronously with a synchronization message. CAN bus master control CAN bus 01011AEN ® Fig. 1: CAN bus with MOVIDRIVE The use of a fieldbus system in drive technology requires additional monitoring functions, such as fieldbus timeout or special emergency stop concepts.

Page 14: Parameter Messages
Configuration and Commissioning 3.1.3 Parameter Messages The parameter messages, too, are divided into synchronous and asynchronous messages. Synchronous parameter messages are responded to within the time interval of 1 ... X milliseconds. The Response message is sent in the 1st millisecond. The response to asynchronous parameter messages is independent of the time interval. - Page 15 Configuration and Commissioning In addition, the terminating resistor must be connected at the line ends. Set the DIP switch identi- fied by an 'R' on drive inverters 1 and 4 at ON. On the CAN bus the IDs listed in Table 5 are assigned as follows: Drive Inverter Message type 1 (Basic ID = 0)
