Table 7.1 (continued) 49 Mode Description • if the setpoints have different signs t1, t3 – moments of change of the counting direction (the appearance of the pulse at the counting input 2); t2 – moment of switching of output 2 in case of coincidence of values of the counting register and setpoint 2; t4 – moment of switching of output 1 in case of coincidence of values of the counting register and setpoint 1 Quadrature / operation with encoders (inP = 6) Input functions: Input 1 – count 1, Input 2 – count 2, Input 3 – reset, Input 4 – block Operating principle: The counting direction is determined by the meanders that come on two inputs.
If the first meander is ahead of the second one, the counter counts the pulses at the first input in the increase mode, and if it
