Chapter 7 High-speed Counter Module AH02HC/AH04HC limit value set, or less than the lower-lower limit value set, an alarm will be generated. 8. Detecting the number of accumulated pulses overflows If linear accumulation is used, users can detect whether the number of accumulated pulses overflows. If the number of accumulated pulses overflows, the overflow flag will be turned ON. 9. Comparing the number of accumulated pulses with a value If the number of accumulated pulses is larger than or equal to the comparison value set, the comparison flag will be turned ON. 10. Resetting a counter A counter can be reset by means of software or an external trigger.
The number of sampled pulses, the number of accumulated pulses, and the number of input pulses can be reset at any time. 7.2 Specifications 7.2.1 Dimensions of AH02HC-5A 35 103 02HC RUN ERROR X0.8+ X0.8 - X0.9+ X0.10+ X0.9 - X0.10 - X0.11+ X0.11 - X0.0+ X0.1+ X0.0 - C0 X0.1 - Y0.8 Y0.9 C1 6 Unit: mm 7.2.2 Specifications for AH02HC-5A 7-3 110 Item Specifications Number of channels 2 channels Input (differential signal) Channel 0: X0.8+, X0.8-, X0.9+, and X0.9- Channel 1:
