AH500 Module Manual The conversion results are shown in the following table. 2. If the value in CR#2 is 0, the external input terminals do not filter pulses. If the value in CR#2 is larger than 19, the value will be counted as 0. For example, if the value in CR#2 is 10, the filter coefficient is 5.187988 2 85000 4 10 = + (KHz). That is, the input signals whose frequencies are larger than 5.187988 kHz are filtered out. 3. 7.9.4 Cycle of Reading the Number of Pulses [Description] If bit 0 in CR0/CR28/CR56/CR84 is turned from OFF to ON, the number of pulses received by the input terminals will be read according to the cycle set. The setting of a cycle is shown below.
If the setting value is larger than 1000, the cycle will be counted as 1000 milliseconds. If the setting value is less than 1, the cycle will be counted as 1 millisecond. 7.9.5 Counting Parameters [Description] Bit 0~bit 15 are described below. 7-20 N kHz N kHz 0 The setting of the frequency of an input pulse is disabled.
