High-Speed Counter Function
What is Counter Function?
●
Counter function counts the input pulse number and reflects it into
the current value. Also, it sets the offset value by recording data into
the current value.
●
Pulse I/O unit has 4 channels of 2 phase input counter. There are
three types of 2 phase input mode as follows.
1) Direction Control Mode
2) Individual Input Mode
3) Phase Input Mode
●
Particular to Pulse I/O unit, the connection point (condition) of pulse
signals to be counted can be selected.
1) Counting inputs from I/O connector.
2) Pulses generated from pulse output or PWM output function
are counted via internal connection.
