Chapter 7 High-speed Counter Module AH02HC/AH04HC 7.9.7 Number of Input Pulses [Description] The number of input pulses is stored in a pulse input register. If bit 0 in CR0/CR28/CR56/CR84 is turned ON, and the parameters are set correctly, the system will start the count. The number of input pulses is neither prescaled nor averaged. The input pulses are count circularly. The number of input pulses is in the range of -2147483648 to 2147483647. Number of input pulses 2147483646 2147483647 -2147483648 -2147483647 0 to If 1 is added to 21478473647, -2147483648. 21478473647 will become 7.9.8 Error Codes [Description] The error messages are shown below.
