The controller is equipped with 2 independent counters with inputs that can be configured for 5 V or 24 V voltage level. The required voltage level is determined by the user program with the Counter[0x].5/24V Mode system parameter. Input A is the counter input, B is the count direction input and input Z (zero track) is used to reset. Alternatively, all inputs are 3-bit Gray code inputs (in decoder operation) The following modes of operation can be implemented: Counter function 1 (depending on the count direction input signal) Counter function 2 (not depending on the count direction input signal) Decoder operation with attached absolute rotary transducer
