for stepper motor drive signal ;
CP:
pulse signal
CW:
direction signal
0PT0:
Public male end before the two signals
2.
RUN:
Start running the program, The same function as
“
Run
”
of the operation panel;
3.
STOP:
Pause program is run automatically, The same
function as
“
Pause
”
of the operation panel, After starting
again, the program continues to run;
4.
A:
A operation
B:
B operation
“
A operation
”
and
“
B operation
”
this is a major feature of the controller:
For stepper motors, we generally quantitative positioning control, such as controlling the
displacement of the motor must be running at a constant speed
，
In this way it is easy to solve,
just put the amount and speed of displacement of the programming can be.
But there are quite a lot of control is not positioning in advance, such as controlling the
stepper motor in one direction from the starting point to start running until he hit a switch after
stroke stop, then reverse direction back to the starting point. Another example requires the
stepper motor running back and forth between the two limit switch several times, and so on. In
these operations, we do not know in advance the specific value of the stepper motor
displacement, and how they should be programmed it? The controller uses: to interrupt the
operation, which we call "A Operation" and "B operation
”
,for example," A operations", workers
workflow is: when the program is running. If "A operation" signal input, motor decelerates to
stop, Program interruption, the controller remembers interrupted coordinate values, the program
jumps to the "A operation" entry address specified programs run the program;

called the input signal, they have the same input interface
circuit.

called the output signal. They have the same output interface circuit.
Both input and output optical isolation circuit to ensure that the internal and external controllers
do not interfere with each other;
The state of the input signal and output signal, corresponding indicator on the panel. For input,
input low (switch is closed) Indicator light; For output signal, the output 0 is low, the light is off,
the opposite will light.
