Driver/hardwares selection for 6kw CNC spindle motor

[applebuet]

Hello

I want to build up a one axis CNC milling machine.  I would like to get a Spindle motor of 6Kw motor.

The motor link is http://tahnzy.en.alibaba.com/product/805968599-218252357/6_0kw_chinese_square_air_cooled_spindle_mot...

My question is what kind of drivers or hardwares do i need to control the motor speed from labView Vi. Does anyone have any suggestion which driver would be suited for labView control?

Regards

Is this a servo motor?  If that is the case you could use one of the Kollmorgen AKD servo drives that National Instruments sells?  In order to control it in LabVIEW and MAX, you would need a PCI-7340/7350 motion controller.  If you are using an AKD drive you would be able to use a UMI-7772/7774 to interface the controller to the drive and perform moves in LabVIEW.  If you deside to use a 3rd party drive that National Instruments does not sell, you can still use the UMI-7764 to break out the motion i/o signals from the controller.  Then you can wire the step/direction or analog commands to whatever drive you choose.

Dear Sir

Thank you for your helpful relpy.

Probably i was not clear enough in my probelem descirption.

actullay, in my one axis cnc milling device,I have two motor.
1. NEMA 34 stepper motor(34Y214S-LW8 Stepper Motor)
2. 6kw CNC  Spindle motor(http://tahnzy.en.alibaba.com/product/805968599-218252357/6_0kw_chinese_square_air_cooled_spindle_mot...)

The stepper motor will provide the one axis motion of the CNC machine while the spindle motor will be used to get the milling thin aluminum plate.The spindle motor (6kw 220/380V) in the middle rotates in different speed to attained the different predefined cutting speed.(10000-15000 rpm). While cutting operation the depth of cut will be given by a ball screw rotation. The ball screw will get power from the  stepper motor. The steeper motor will take the spindle motor backward and forward by this ball screw rotation.(shown in attached figure)

Kollmorgen AKD servo drives can control both the stepper and spindle motor together with the help of PCI-7340/7350 motion controller. Then how should I connect them to each other?

Host computer (labview.vi) to UMI-7772/7774 interface to PCI-7340/7350 motion controller to AKD driver to stepper motor and spindle motor?

(Sory, I am very novice to these area, may be my questions are not up to the mark)

Hello,

Each motor will need its own Drive.  The AKD servo drive cannot drive current to a stepper motor.  The PCI-7340/7350 can implement both servo/stepper control depending on how you configure the axes.  Using the motion controller you will then use a UMI-7772/7774 board to break out the control signals.  For stepper motors we sell Danaher P7000 series drives.  Here is a link to the user manuals for our NI-Motion Controllers.  Please take a look at the getting started guides for AKD Servo Drives and P7000 Series Stepper drives.  I think this is a good start for the information you are asking about.

Dear Sir

I have studied your provided link. I tried to summaries the all the hardwires and their mutual connection as shown in the pic. It would be nice to have any suggestion for this arrangement.

Still I was not able find any connection cable to the motors from those P7000 and AKD drivers. Specially, I have no idea about the connection from AKD driver to Spindle motor. I do not have the 6kw air cooled spindle connection diagram/manuel. So it is hard to guess the right cable for this AKD driver.  

If you have any recommendation for any specific cable from national instruments for these to motor connection, you are welcome.

Unfortunately National Instruments does not sell specific cables for motors.  Generally this is because all motors have the same contol lines and connect directly to the drive.  The use manuals for drives indicate which pins/ports are used to wire to the motor.  I believe the servo drive comes with a combicon connector screw terminal to wire the more.  The inputs should adhere to the normal stepper/servo conventions.  If you are looking to create a longer cable you may need to contact the motor manufacturer for information on how they've color coded their wires.
