The HiCON is strictly for stepper motors isn't it?
But it does offer encoder feedback to keep track of position.
So shouldn't it also run brush servo's?

Hi Tim,
Since it only outputs step and direction for each axis it can only run steppers or servo drives that take step and direction input.

Ahhhh, so it will run Gecko 320x's then.
Good to know.

Is the encoder input for closed loop with the servo controller or with Mach3 software?.I have 3 AC servo amplifiers with encoder input and I want work with linear encoders in the 3 axis of my CNC router for backlash correction.
Thanks.

currently there are no PID loops inside HiCON to do closed loop control. however if you use encoder feedback from motor or glass scale, it is used as the starting point of every move, so if there are any lost steps by the motor, they will be removed when the next move is started. www.machmotion.com (http://www.machmotion.com) has done many HiCON installations using AC drives in this setup with excellent results. They also use differential step/dir signals which virtually eliminates any loss of steps.

Thank you very much for your reply, Rufi.

Hello , i have purchased machmotions full lathe kit with 750watt Teco servos & drives , and the hicon controller. if anyone has recommendations for settings please share any info you may have. I have a rotary encoder running at a 1:1 ratio with the spindle, and the main motor is powered by a 3hp mitsubishi vfd. I have the machine to the point where it will respond to basic g-code commands. I will be checking back frequently throughout the day if you need any more information just let me know. Thanks guys.

Say I was doing a circle and Y axis missed ten steps, it will then correct things during the next quadrant? If the servo went too far, that will not be stopped from happening?
What if I have to go to X0 Y0, from a rapid of course where lost steps are very likely to occur, and start drilling then move to X1 Y1 for another drilling cycle. If, during the rapid, the axis didn't move far enough, and it went to X-.005 and Y-.010 will things get corrected before it pecks in the wrong location or not? Will the next set of holes be drilled in X.995 and Y.990?
-
Hello sir,
For example if you move the X axis from 0 to 1.00 and it stops at 0.995. If you then move the X axis to 2.00 the controller makes a calculation based on the current position (0.995) to correctly move to the target destination. In that case, the controller will calculate a distance of 1.005 to move in order to get to the next position (2 - 0.995 = 1.005).
Because of this, tiny offsets aren't cumulative.
I hope this answers your question.
-
Only question left is whether this "closed loop" will stop a move when the target has been reached?
-
Hello,
When using encoder feedback, the encoder value is used as a starting point before doing the move. The motion will end once the calculated distance has been passed. Aside from that, the encoder value is continuously checked for max following error. While all this is happening, the Mach3 position DROs show the actual axis position, which is the value from encoder feedback.

Can I hit cycle stop in the middle of a program with your Hicon connector and I won't have any problems? Currently that situation with teh ESS is leaving a bad taste in my mouth. Having to press feed hold, waiting for motion to stop and only then being able to hit cycle stop.
-
with hicon, the feed hold is instantaneous. no delay to empty the motion buffer. If you hit stop, with or without feedhold, the motion will stop right away, but you will have to do "start from here" from a previous line in gcode so mach3 can regenerate the motion data.
hope this helps

If I hit stop without first hitting feed hold, will teh Hicon lose communication with MACH?
-
no. not at all

Sounds like I will be taking that to the bank ;)
