Front panel

The front panel includes a chart (see below ) :

1 , eight digital display

2 , six input status indicator

3 , triple output status indicator

4, CP pulse signal indicator

5, CW direction level indicator

6 keys : A total of 10 keys, and most of the key composite keys, different functions in different states they represented , the following description, we only pick up one of the functions indicated keys.

 

 

The rear panel diagrams and signal descriptions

The picture shows the rear panel terminals, including ( as shown below )

1, CP, CW, OPTP stepper motor driver control line , the three ends are connected to the respective ends of the drive , wherein:

CP ---- pulse signal

CW ---- motors turn signal level

OPTO ---- Public male end before the two signals

CP, CW corresponding status indicator on the front panel

2, start : Start the program to run automatically , equivalent to the start button on the front panel .

3 , Stop : Pause the program is running , the equivalent of the stop button on the control panel , start again , the program continues to run.

4, A and B, the operation is a major feature of the operation of the controller: the stepper motor, we generally quantitative positioning control, such as control of a motor displacement is easily solved in this way a constant speed , the speed only volume and the amount of displacement can be programmed . But there are quite a lot of control is not pre- positioning , such as controlling the stepper motor starts running from the starting point in one direction until he came to a stop after the trip switch , run back to the starting point and then reverse course . As another example requires n times stepper motor running back and forth between the two limit switch, and so on. In these operations , however, we do not know the exact value of the displacement of the stepper motor , and how they should be programmed it? The controller uses : "Interrupt Operation" , we call it "A Operation" and "B operations ." In "A operation " for example , the workflow is: When the program is running, if the "A Operation" and the signal input , motor for deceleration stop , interrupt the program , the program was interrupted remember coordinates the program jumps Go to the "A operation" entry address specified by the program , run the program .

5 , inputs 1 and 2 via switch input.

6 , output 1, output 2 and output 3 by switching output.

7, COM +, COM- external input and output switching power supply , the power supply is DC12V/0.3A, COM + is the positive terminal , COM- negative side, this power is supplied by the controller internal isolation .

8, ~ 220V power input controller .

 

 

The input signal and the output signal interface circuit :

      The controller is the "start" , " stop ", "A operation ", "B operation ", "Input 1", " Input 2 " as the input signal , they have the same input interface circuit . "Output 1", " Output 2 ", " output 3" called the output signal. They have the same output interface circuit. Input and output circuits have optical isolation to ensure there is no interference with each other inside the controller , the controller inside the power supply (+5 V) and external working power (+12 V) are independent, and there is no electricity connection , these two sets of power from the control two independent internal transformer windings provide .

      Status of the digital input signal output signal , corresponding LEDs on the front panel . For input, input low ( switch closed ) lights, and vice versa lamp ; For output, the output 0 is low, the light is off , and vice versa lights.

Operation Flowchart

Controller always operate in one of four states: automatic mode, manual mode, the program edit mode, parameter setting state. On power-up or press [ Reset ] , the controller is automatically to be running and make coordinates in zero , then you can start the program to run automatically or switch to manual mode, the program edit state and parameter setting status can only switch in manual mode . After completion of the program to edit or parameter setting is complete, press [ Exit ] key to return to the manual state ( the program will automatically be protected ) . In manual mode , if you want to switch to the program edit mode, simply press the [ EDIT] key , if you want to switch to the parameter setting state , press [ edit parameters ] button for 2 seconds or more.

      ( Note: The above mentioned keys [ Edit ] , [Program Participation ] , [ Exit ] is actually the same key , consists of three functional complex , we introduce a function, the button name only choose one , the same below )
