DANAHER AHD70E4-44S Servo motor

Operating modes of the serial interface COM1 The operating mode of the interface has to be set according to the application in each case: – Programming and test or – Man–machine–communication MMC Active mode: The active mode is used for programming and testing the central unit, i.e. it gives the user access to all the programming and test functions of the central unit. Passive mode: The passive mode is used to perform a communication configured with the DRUCK and EMAS blocks between the user program and a device connected to the serial interface.

Temporary interruption of the passive mode While a communication between the DRUCK or EMAS blocks and a device connected to COM1 is being executed, it may be come necessary to modify the program, for example. For this purpose, you must switch over COM1 from the passive mode into the active mode.

Switch-over: Passive mode

The default End-of-text character for the sending direction (CR) is not sent. Nevertheless, this default End-of-text character (CR) must not appear in the message text of the assigned DRUCK block. 2) For the direction of reception, an End-of-text character is always necessary. This default End-of-text character (CR) must not appear neither in the message text nor in the user data of the assigned EMAS block. For the passive mode of COM1, the interface parameters can be changed using the SINIT function block. If the changed values are not plausible, the COM1 interface uses the default values. The interface is newly initialized each time the operating mode is switched over. The active-mode parameters are set in the active mode, whereas in the passive mode the parameters established by the SINIT block or the default values are set.

Networking interface

 The 07 KR 91 R252 central unit is equipped with a special parallel interface. It is thus possible to network it with another bus system using an additional communication processor module. The additional communication processor has its own housing. Both housings (of the 07 KR 91 R252 and of the communication processor) are assembled by means of a snap-on connection.

The high-speed counter used in the central units 07 KR 91, 07 KT 92 and 07 KT 93 works independently of the user program and is therefore able to response quickly to external signals. Its features are as follows:
The counting frequency is max. 10 kHz. The counter counts the 0–>1 edges at terminal 02 (also designated as E 62,00).
The counter counts upwards from –32768 to +32767 (8000H...7FFFH). If +32767 is exceeded, the counter skips to –32768.
