Re : Problem with current position (UMI-7764)

[tomada]

Good afternoon,

I'm using servomotors PSKF321 (SEW) and servodrives MDX61B (SEW). I'm using the PCI-7344/UMI-7764 to control the motors. When I was performing some tests in MAX, I realized that I don't have feedback from axis 2, 3 and 4. Axis 1 is working fine, i can control perfectly the motor, I can make movements to different positions. I checked the connections from the drive to the UMI and they are the same that i used to axis 1. I changed to other axis and it doesn't work. I tried to change the connections from the axis2 and 3 to axis 1 they work. I tried to put in annex the xml file related to the configurations of the PCI but it wasn't accepted. It is possible that my problem is a wrong configuration of the PCI?

Thanks for your time,

Hi Tomada,

Have you been through the  UMI user guide ? 

Also, it looks like the wiring might be the cause. Do you supply each terminal block on the 7764 (5V) ?

Best regards,

Good afternoon,

I'm sending the connections that I made in the UMI-7764.

Thanks for your time,

another thing, why only the axis 1 has PWM and the others don't have?

[tomada]

The inhibit output from axis1 doesn't commute also. When the motor arrives to the limit sensor, the inhibit output voltage doesn't change. In the motion I/O settings, in MAX, we didn't notice any change in the voltage by software, only when was commuted the switch S1. We are trying to program the inhibit output like the table presented in the bottom

X+   X-   Inhibit output

0     x    0

x     0    0

1     1    1

X+  limit X+

X-   limit X-

we also notice that the inhibit output doesn't change, no matter we press the halt, kill or start button.

The cable that links the PCI-7344 and the UMI-7764 is the 186381D-02. It is the right cable?
