Controlling a Nanomotion motor with LabVIEW?

[MarcusTörndahl]

What do I need to run a Nanomotion motor with LabVIEW?

LabVIEW - Controller - Driver - Motor

The Nanomotion motor which I intend to use is a HR4, for alignment purposes in a cleanroom environment. Do you have any experience in using this or other Nanomotion motors please add a comment to this post.

Regards,

Marcus,

some years ago I have used an NI 7344 motion control board to control a Nanomotion ultrasonic actuator. I don't remember the model type of the drive, but it has provided a +/- 10 V command input. The position feedback signal came from a quadrature encoder.

In fact NI's motion control R&D has worked with Nanomotion to implement some features into the control algorithm of the 734x and 735x boards to optimize the control behavior for Nanomotion actuators. The most important parameters, that were added to support these motors are the foward and reverse offset voltages to configure the static friction deadzone.

Brief explanation: There is a deadzone of approximately +/- 2 V at the command input, where the motor doesn't react to command voltage changes. The 734x and 735x boards can avoid this deadzone. Otherwise it would be very hard to properly control the actuator.

I hope that helps,

Hi do you have any feedback simular to encoder or drive in open loop...? It should work with the unit I use today because it can control DC motors with feedback. Nanomotion state that you can use off the shelf servo driver.... contact www.robotservice.se they have help me with my driver to control a DC motor with only hallsensors as feedback they made an special SW for me without charge...
