  • Page 11: Operating Modes Of The Counter

    4. Operating Modes of the Counter For best survey, all parameters of the unit are arranged in 13 expedient groups, named “F01” - “F13”. Depending on the application, only a few of these groups may be important, while all other groups may be irrelevant for your specific application. All details about configuration and function of the parameters can be founds in chapter 6.

    4.1. “Single Mode” (encoder 1 only): F02.004 = 0 Only the inputs of encoder 1 are active, signals on the encoder 2 inputs will not be evaluated. Besides the actual counter value, the unit also records minimum and maximum values, with regard to the last Reset of the Min/Max memory.

  • Page 14: Dual Mode (Encoder1 And Encoder 2 Independently): F02.004 = 1

    4.2. Dual Mode (encoder1 and encoder 2 independently): F02.004 = 1 Both, encoder input 1 and encoder input 2 are active and the frequencies are evaluated independently, Besides the actual measuring values the unit also records the minimum and maximum values of both channels, with regard to the last Reset of the Min/Max memory.

    4.3. Sum Mode (encoder 1 + encoder 2): F02.004 = 2 Both inputs, encoder 1 and encoder 2, are active. From both values the unit forms the sum, with consideration of the individual scaling of each channel. The final result can once more be scaled into user-friendly engineering units by means of the special scaling parameters in parameter group F02.

    4.4. Differential Mode (encoder 1 - encoder 2): F02.004 = 3 Both inputs, encoder 1 and encoder 2, are active. From both values the unit forms the difference, with consideration of the individual scaling of each channel. The final result can once more be scaled into user-friendly engineering units by means of the special scaling parameters in parameter group F02.

Both speeds are multiplied to form the product, with consideration of the individual scaling of each channel. The final result can once more be scaled into user-friendly engineering units by means of the special scaling parameters in parameter group F02.

The unit calculates the ratio of the two speeds, with consideration of the individual scaling of each channel. The final result can once more be scaled into user-friendly engineering units by means of the special scaling parameters in parameter group F02 (conversion factor K = F02.09 : F02.08), see figure below*).

However, changes during normal operation will not be considered, unless upon special remote command.
