MotionKing 60BLS70A-240-1000Z motor; http://motionking.com/Products/Brushless_DC_Motors/DC_brushless_servo_motors.htm Just as the link says, it is brushless DC servo motor, just that it is custom made for 24 VDC rated voltage and with custom diameter output shaft. Here is the datasheet of my motors: http://www.cutting.lv/fileadmin/user_upload/60BLS70A-240-1000Z.pdf BTW I have another 4 motors identical to these for a machine I am currently building for my own use. If there are no other options, I could swap the one for Z axis to a stepper motor and ship it to You for testing. You could ship it back next time I make an order... I just tested the motor in q mode: 1) init pin connected to halui.machine-is-on; 2) encoder velocity monitored in vcp panel; bldc value set with a slider in vcp panel - min and max values are -0.95 and 0.95 respectively, increment is 0.01; 3) I enable the motion and watch velocity pin - I wait for the motor to be homed and when it is done (encoder velocity is 0.00 again), I start changing bldc value; 4) for value = 0.95 I get approximately 900 RPM, with value = -0.95 I get approximately 1100 RPM. So is it something wrong with config/parameters? Here is my main HAL file, derived from hm2-servo sample config: http://pastebin.com/V3D8tfY1 Is there anything else I can do to provide some useful data? -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
