Oriental Motor EMP 400 Controller wiring

[nibin89]

Please help me connect the inputs and outputs of the EMP 402 to my PLC.

As far as i know, i understand that the input pins and output pins from the CN1 cannot be directly connected to the PLC (an inbetween convertion circuitry is needed).

My requirement:
I need a 24 V or 0 V state change from the CN1 pins ALM and READY. (EMP Outputs)
Also how can i connect my PNP sensors to the IN1, IN2, M0, M1, START pins of the EMP CN1. (EMP Inputs)

Please help.

Thank you in advance.

Hi,

Many of our products are designed to be controlled with a PLC; including the EMP series controllers. Please see the following wiring diagram for the CN1 connector on the EMP controller (scroll down to view entire diagram; inputs on top/outputs at bottom):

Your PLC would be the "host controller etc." on the left. There's only one way to wire the EMP controller, so just follow the wiring diagram.

The EMP outputs are open-collector types so you'll actually have to supply 5 to 24VDC to our outputs from your PLC's input. All our output circuit does is open and close the transistor to GND. If no voltage is supplied from the PLC side, then no voltage will be output when the output turns on/closes. You'll need PNP output transistors on your PLC's input side since we're sinking on our side.

You will also see from the wiring diagram above that you can only use NPN transistors with our CN1 inputs.

Here's the link to the EMP series operating manual: http://www.orientalmotor.com/products/p ... 036-3E.pdf

Our newest controller, SCX11, offers both sink/source as well as 5v/24v I/O capabilities and a GUI software. It may work for you, but it's only designed to control one motor/driver at a time. The EMP402 model is a dual-axis controller. For more information on any of our product models, please do a part number search on our main website.

Let me know if you have any questions.

Thank you for the reply.

Actually speaking, i am using a Digital Input Output card for controlling the EMP. NI 6514 to be precise.
Normal direct connection to the card does not yield any output.

I have attached here with the NI DIO Card Input and Output Circuitry.
Please help me verify the connection diagrams for the EMP inputs and Outputs attached.

Thank you in advance.

Thank you for the valuable information.

I had made the circuit i attached previously and connected to the EMP 400.
I am getting the desired output (only ALM) and Input from the EMP.

But there is a problem with the READY Output.
Even when the EMP is solely functioning and i type 'r' in the hyperterminal, i always get READY = 0.

The READY output is always zero and never am i getting a 1 in the hyperterminal. (even after 3 sec after power on, as said in the manual)

Please help.

The READY output will only turn on when a program is not already executing or being modified. Do you have a program named "99" or "CONFIG"? Type "EDIT" and then ENTER to get into your program directory to see if that program exists. Program "99" automatically executes upon power-up or RESET command. Either delete that program or change the name to something else. You can also tell if a program is already running by simply trying to run another program. If a program is already running, it cannot execute another program. It will give you an error message. Press the ESCAPE key to immediately exit the program.

If the READY output bit never changes to "1" or on in the R status report, then we may have a damaged output circuit. The ALM and READY outputs wire to the EMP in exactly the same way.

Do you have any alarms? What type? Do you have the E-STOP input wired to -COM?

Hi aldoned,

With the EMP series controller, only the ALM output NO/NC logic can be changed with the ACTL command.

Please see PAGE 63 of the manual for more info:
