Anaheim Automation stepper motor with PCI-7330 and UMI-7764

[Rob McCracken]

Hi, I'm fairly new to LabView 2010 and stepper motors in general. I've been trying to get an Anaheim Automation stepper motor and encoder to work with LabView with some success but it isn't quite right. My main problem is when the home switch is activated the whole thing is killed and I cannot get it to respond unless I manually turn the motor so that it is not on the home switch anymore. After that it will run ok, unless it hits the home switch again (btw if it hits the forward limit switch it will stop but it will accept a command to move away from it).

Could someone please take a look at my wiring diagram in the link below and let me know if there is anything obviously wrong with how I wired it up or if you have any suggestions on where my settings might be going wrong I'd really like to hear from you. 

Thanks,

Rob

Hi Rob,

Thank you for posting on this forum.

After a quick glance at your wiring, I believe that everything has been connected properly. Can you also please post your code so that I can have a look at what you are trying to achieve.

Thanks,

Thanks for the reply, I am trying to run any of the find reference example VIs from NI. I've not edited the code in any way.

The motors will run with the wiring I've posted, it'll move to the forward limit switch then come back again but it will then hit the home switch, the motor stops and cannot be started again until it is manually moved off the home switch. It has never made it all the way to the reverse limit switch meaning I cannot use home (it stops) or the centre (can't find the reverse limit) as a reference point.

It was suggested to me I might have the grounds miswired, the manuels were not all that clear so I'm unsure.

Hello! I know it´s been 6 years, but, did you find the solution? I have a similar problem, I can move the motor but when the home sensor change state (low to high or high to low) the stepper halts without finish the specified path, but I can move it again if I send the move signal again. I can´t find any information about why this happens. Regards
