Cumulative Gate Mode
The High-speed Counter Unit in this mode counts the number of pulses within
a range of –8388,608 to 8,388,607 while control input IN2 is turned ON to
accumulate the count value.
The count value is reset at the rising edge of control input IN1. An external
control input or an IR bit can be used as the control input.
In this mode, the count value will be reset when control input IN1 is turned
ON.
The High-speed Counter Unit counts the number of pulses while control input
IN2 is ON. The count value will be kept on hold while IN2 is OFF. The count
value is accumulated whenever control input IN2 is ON.
The High-speed Counter Unit in this mode does not have any external output.
4-8
Sampling Mode
The High-speed Counter Unit in this mode counts the number of pulses
between for a preset interval. The High-speed Counter starts counting the
number of pulses from the rising edge of the control input IN1 within a range
of –8,388,608 to 8,388,607. An external control input or an IR bit can be used
as the control input.
In this mode, the number of pulses will start counting from 0 when control
input IN1 is turned ON and the timer for a preset sampling time will be turned
ON at the same time. When the time is up, the High-speed Counter Unit will
stop counting the number of pulses and keep the count value on hold.
