Delta ASRTU-EC16AP1TA - Counter Channel 1 Inputmode (3001: 02 H)

Chapter 6 Introduction of Parameters
6-11
6_
Value Description
1
The channel 1 high-speed counting function is enabled; ASRTU-EC16AP1TA’s counter
channel 1 starts counting immediately and the counting continues from the last recorded
counter value.
2
The function of clearing the counter value to 0 is enabled; the count value of
ASRTU-EC16AP1TA’s counter channel 1 is cleared to 0 and meanwhile counter channel 1
stops counting immediately.
Note:
Please connect a resistor of 2.2K ohm between the input points and S/S common terminal when the input
frequency exceeds 100 kHz.
6.4.2.2 Counter channel 1 InputMode (3001: 02h)
The parameter sets the input mode for counter channel 1. ASRTU-EC16AP1TA supports three input modes:
single pulse, “pulse + direction” and “phase A + phase B”.

The input mode for high-speed counting has to be set up before the high-speed counting function is enabled.
You can select the corresponding mode according to the actual pulse input type.
