3.3.5. Differential switching conditions
Event Description of the Switching Condition
[c1 – c2]
≥
Differential
Setpoint
The absolute value of the differential position between encoder1 and
encoder2 is higher or equal to the differential position setpoint of the
corresponding function
[c1 – c2]
≤
Differential
Setpoint
The absolute value of the differential position between encoder1 and
encoder2 is higher or equal to the differential position setpoint
3.4. Generation of an Output Signal
As a first step we have to arrange the desired Switching Events, which can be composed from
any combination of the switching conditions as described above. Every event consists of one or
several conditions according to the selection of check boxes on the PC screen (see 4.3). Several
events (1 - 4) are combined to a Switching Function. The parameters named "Target Function"
allow the assignment of an output to each function, where the switching signal finally appears.
Also the internal status bits become accessible via output if a corresponding assignment has
been made. The assignment of outputs uses an 8-bit binary code as shown below.
