Chapter 7 High-speed Counter Module AH02HC/AH04HC 7.2.5 Functions of AH02HC-5A/AH04HC-5A 7-5 Item Specifications Maximum The maximum frequency is 200 kHz. frequency of counting The number of sampled pulses is in the range of -200000 to 200000. The number of accumulated pulses is in the range of -999999999 to 999999999. The number of input pulses is in the range of -2147483648 to 2147483648. Specifications Range Linear count Circular count Type CH0: X0.0+ and X0.0- CH1: X0.1+ and X0.1- CH2: X0.2+ and X0.2- CH3: X0.3+ and X0.3- Input (differential signal) RESET input Signal level 5~24 V DC Maximum 15 mA current Channel 0:
The high-speed pulse output Y0.8 is a transistor whose collector is an open collector. Channel 1: The high-speed pulse output Y0.9 is a transistor whose collector is an open collector. Channel 2: The high-speed pulse output Y0.10 is a transistor whose collector is an open collector. Channel 3: The high-speed pulse output Y0.11 is a transistor whose collector is an open collector. Output type Comparison output 24 V DC Signal level Maximum 15 mA current Function Description Enabling/Disabling a count 1. Users can enable or disable a channel. 2. If unnecessary channels are disabled, the internal operation will become more efficient.
Accumulation counter Linear count The number of accumulated pulses is in the range of -999999999 to 999999999. If the number of accumulated pulses is not within the range, the overflow flag will be turned ON. Circular The number of accumulated pulses is in the range of -999999999 to 0, or in the range of 0 to 999999999. count Comparison If the number of accumulated pulses meets the comparison condition set, the comparison flag will be turned ON, and a signal will be output. Users can reset the comparison condition. Sampling counter Setting a cycle Users can change the cycle of updating the number of sampled pulses or the cycle of updating the number of accumulated pulses.
Averaging The number of sampled pulses is divided by the number of cycles set by users. the number of sampled pulses Prescaling The number of input pulses is multiplied by a scale.
