Counter Function
Counter functions include 1-stage counting, 2-stage counting, batch counting, total counting and dual counting.
1-stage Only 1 SV is allowed. See “output modes of counter”.
2-stage 2 SVs, 2 PVs are allowed. See “output modes of counter”.
Batch Apart from the counting of PV and SV, when PV=SV, the batch counting adds 1 and clear PV as 0 for
recounting till the batch counting equals batch SV.
Total Total counting adds up all the counting values till they reach SV for output.
Dual CP1 and CP2 can be independent counters, but the counting speed can only reach 5kHz. CP1 and CP2
can execute addition
or subtraction .

Output modes of counter
:
The output of SV can be 1-stage or 2-stage. When the output is set as 1-stage, Output 2 will be the same as the Output 1. The
output modes include: F, N, C, R, K, P, Q, A, S, T, D
F When PV reaches SV, output is enabled but counting continues. Recounting starts after reset signal is over.
Output 2 remains.
N When PV reaches SV, output is enabled but counting stops. Recounting starts after reset signal is over. Output 2
remains.
C When PV reaches SV, recounting executes automatically. Output 2 is pulse output. Output 1 remains till Output 2
is over.
R When PV reaches SV, counting stops till Output 2 (pulse) is over for recounting. Output 1 remains till Output 2 is
over.
K When PV reaches SV, output is enabled but counting continues. Recounting starts after reset signal is over.
P When PV reaches SV, output is enabled and recounting is automatically executed. But display of counting
remains till Output 2 (pulse) is over.
Q When PV reaches SV, output is enabled but the counting continues. Recounting starts after Output 2 (pulse) is
over.
A When PV reaches SV, output is enabled but the counting stops. Recounting starts and Output 2 (pulse) executes
after reset signal is over.
S When PV ≥ SV1, Output 1 is enabled. When PV ≥ SV2, Output 2 is enabled
T When PV ≤ SV1, Output 1 is enabled. When PV ≥ SV2, Output 2 is enabled.
D When SV=PV, output is enabled but counting continues. Addition and subtraction modes are valid.
The time of Output 1 and Output 2 (pulse) can be setup separately, ranging from 0.01 to 99.99 secs. Recounting refers to counting up or
addition/subtraction counting starting from 0 and counting down starting from SV. The counting range: -99999~999999. The counting
will restart from 0 if the counting exceeds the range.

Save the data before power off : When is set, the current PV will be saved. When is displayed, the
PV will be cleared.
Pre-scale function : When conducting unit conversion, PV = PV x PreScale value, ranging from 0.001 to 99.999.

Delay time after switching on the power : The tachometer will start to run when the set delay time is due after the
power is switched on. (Range of delay time: 0.1~99.9 secs.)
Setup average value of input filter : Range for obtaining average (n = 0 ~ 3). This parameter obtains the average of 2 n
input data for more stable output value.

Timer + Counter Mixed Function
In Timer + Counter function, SV1, PV1 and Output 1 are for Timer; SV2, PV2 and Output2 are for Counter. DIP switch is
disabled. All timer and counter functions remain except
․
RCY2, SCON, STON, STOFF in output mode of Timer function
․ Command up/down, Individual up/down, quadrature counting in input mode, S, T, D in output mode of Counter function
Only 1-stage counting in Counter function is available.

Easy DIP Switch Setup
Users can use DIP switch to setup parameters. When DIP is switched to ON, the corresponding parameters can only be
read, not changed.
