Control Connector (15 pin) Checking the Dir(CW) Pin#4 and Dir(CCW) pin#12

[lll]

Hi,

I want to check the output (digital 5V) from my Control Connector in the UMI-7774 on Axis#1.

The Control Connector (15 pin) has Dir(CW)  Pin#4 and Dir(CCW) pin#12

which i need to connect to my Servo motor drive (Forward and Reverse inputs in the Motor Drive, Both 24VDC).

I connect these pins : Dir(CW)  Pin#4 and Dir(CCW) pin#12 to the Forward and Reverse inputs in the Motor Drive,

I use a 24vdc relay with 5v coil (of the relay), and as i test it in Motion Assistant the Servo motor NOT MOVE !

So, i wanted to test if the  Dir(CW)  Pin#4 and Dir(CCW) pin#12 actually output 5v and i connect for each one led (with resistor).

The circuit i connect for testing that is this:

[pin#11  (Digital ground)  ] ---- [LED] ---- [RESISTOR] ---- [pin#4 Dir(CW) ]

same for pin#12 Dir(CCW)

i start Motion assistant for Simple move. Straigh Line Move. I hit "Start" and Nothing.. The Servo Motor doest move.

Please Note that  the encoder of the Servo Works Fine. When i move manualy(by hand) the Motor

I see in the MAX that the encoder position changes.

In Addition, When i input 24vdc into the Motor Drive,

 (i connect the 24vdc common into the Forward Input of the Motor Drive, in order to set the Motor Drive to Move Always Forward)

and then use the MAX or other Sample Program For simple move on One-Axis its work,

The Servo Motor Run and stops, i get the values from the encoder, the servo move.

BUT, why i cant move the Servo when the Dir(CW)  Pin#4 and Dir(CCW) pin#12 connected Directly (through 24vdc relay offcurse)

To the Motor drive as it should be.

attached image for my umi and motor drive, the way i connect it.

Thanks for any help.

Best Regards,

Moti Mor

Sorry, another thing...

The led also is off, so i didnt know why the umi doest output 5V to move the servo Forward (Pin#4  CW)

I'm Using :

LabView 8
Motion Assistant 1.3
Latest Version of NI Motion Driver

Thanks again,

Moti

I see no one has responded to your multiple posts over the past few days. I'll try to help but I have no experience with the UMI-7774.

1. Could you please edit your diagram to show exactly how the relay contacts and coils are wired up. My intuiation is that the signals coming out of the UMI are inadequate to turn on the relays. A clear wiring diagram will help me figure out what may be happening.

2. What is the manufacturer and model number of the relays used. Or also provide a web link to a data sheet if possible.

3.  What is the manufacturer and model number of the 3rd party servo drive.

Thanks
