MAX Wiring problems

[joshlismore]

Hello,

I am having problems wiring up my servo motor to the Measurement and Automation Explorer. I am using a UMI7764 and a PCI 6221 with labview 6.2. The third party driver I am using can be found at this adress - http://www.electrocraft.de/produkte/aufdruck/1/21.pdf. At the minute I have the power supply wired to the driver from a 24DC supply and I also have the the UMI 7764 5V supply coming from the driver. I also have the motor and tacho wired up to the driver. I have the encoder also wired up to the UMI. I have tried wiring up the the AOUT1 and AOGND to the + and - setpoints (18&19 in manual) on the driver but the motor still won't operate. ANY HELP would be greatly appreciated.

Regards and thanks in advance.

Josh,

this combination won't work at all. The PCI-6221 is a data acquisition board, while the UMI-7764 is a breakout box for a motion control board like the PCI-7340 or the PCI-7350. The PCI-6221 doesn't provide motion control capabilities and it's not pin-compatible with the UMI-7764.

Hi,

There is also a PCI 7344, I assume I should use this one instead?

Hi Josh

Yes this card should work fine for you. Depending on the number of axis that you want to control and the other features that you may or may not need Ni supply a rage of cards that would suit your purpose but the 7344 seems a safe bet. It is 4 axis and should be compatable with both your breakout box and your steppar motor.

best regards
