Table 7.1 (continued) 52 Name of the mode Input functions Principle of operation Illustration • if setpoints have different signs t1, t2 – the meander at input 1 lags behind the meander at input 2, the counter counts in the mode of increasing the value of the count register; t3 – moment of switching of output 2 in case of coincidence of values of the counting register and the setpoint 2; t4, t5 – the meander at input 1 is ahead of the meander at input 2, the counter counts in the mode of increasing the value of the count register; t6 – moment of switching of output 1 in case of coincidence of values of the counting register and the setpoint 1 NOTICE After reaching the physical limit of the count (if the counter does not reset after reaching the setpoint), the device transfers the overflow result and continues the count.
