4.8.5 The usage of frequency source given by the pulse

The frequency is given by terminal pulse signal in many applications. The specification of pulse signal is as follows: Voltage range of 9V~30V and frequency range of 0 kHz~100kHz. The pulse reference shall be only input from multifunctional input terminal DI5. The relationship between input pulse frequency of DI5 terminal and the corresponding setting shall be set by means of F4-28~F4-31. This corresponding relation is 2-point straight corresponding relation. The pulse input corresponds to 100.0% in setting, which means the percentage of relative maximum frequency F0-10. The specific setting is as shown in the following figure:
