    The terminating resistors can be activated by setting the two DIP switches on the module (switches set to ON).Due to the high class of protection of the servo positioning controller DIS-2 48/10 FB the terminating resistors can not served from outside. To switch on/off the terminating resistors is only possible, if the servo positioning controller DIS-2 48/10 FB is removed from the motor.

    This interface should be as manufacturer-independent as possible. PROFIdrive specifies the configuration, diagnosis, data exchange and state machines with a PROFIBUS master. Furthermore, so-called application classes are defined. There are different PROFIBUS-Manual Servo positioning controller DIS-2 48/10 FB Version 2.0...

  • Page 27: Telegram Editor

    The telegram editor is used to define the way the servo positioning controller interprets the data received and sent. The firmware of DIS-2 48/10 FB servo positioning controllers supports the exchange of data using the DP-V0 service. The data are exchanged cyclically in the form of so-called telegrams.

  • Page 28: Figure 6.1: Composition Of A Reception Telegram

    0..2, a so-called control word is entered at address 2 (length: 2 bytes). This consistent convention facilitates the creation of applications and the use of the Metronix example projects for SIEMENS SIMATIC S7. The other entries can be chosen as desired from the object directory of the parameter numbers.
