[Emc-users] joint following error on resume from vector
Hello, Recently I mentioned that my AXIS is skipping some vectors when I'm resuming program many times. I have heavy modified AXIS and You mentioned that I must show this error in oryginal one. And here it is: this is the file: http://www.pastebin.us/?show=m33d4637c EMC 2.1.6/2.1.7 after start and stop after few vectors I selected vector on line 24, set_next_line and run then EMC execute vector 24 and operate correct. when I.m selecting vector 25 and resume from this line, EMC move to end of 24 vector and then execute 25. EMC 2.2.2 when I was doing either run form 24 or 25 line, following error on axis 0 and 1 is showing. My modifications on AXIS bypass this problem on EMC line 2.1 but I cannot fix problem of followings in 2.2 and use goodies built in EMC 2.2.2 please help regards Michael Polityka, Wprost, PC World Komputer i inne tytuły w Twoim komputerze!

Re: [Emc-users] KBIC Controller
My experince with this kind of controller, although not this specific brand, is that it's chopping the AC wave (using SCRs) to provide a chopped DC output. It's very much light a light dimmer, but rectified. It's a simple and inexpensive way to provide a fixed speed control for something like a conveyor belt, but I'm not sure it would work very well for CNC. I think that the torque curves are different than with straight variable DC as well-less low speed torque. Your assesment is probably correct-that using a PM motor with PWM drive is the best way to go. Javid - Original Message - From: Kirk Wallace [EMAIL PROTECTED] To: Enhanced Machine Controller (EMC) emc-users@lists.sourceforge.net Sent: Saturday, December 29, 2007 11:09 AM Subject: [Emc-users] KBIC Controller I am trying to understand how the KBIC controller works. http://www.galco.com/scripts/cgiip.exe/wa/wcat/webpromo2.htm?promo=120KBIC My understanding so far is: Universal motors are brush motors with windings for the armature and the stator. They can run on DC, or more commonly, AC if both windings are kept in phase. To reverse direction, the polarity of the armature or the stator is reversed. The speed of the motor can be controlled by changing the average voltage to either the rotor or stator by PWM, PDM or SCR (I don't know the term, but like a light dimmer). Because there is mains voltage on the control potentiometer, the KBIC appears to use an SCR to control the passing of mains current to the motor. There seems to be no provision for motor direction control, but an external means of reversing the polarity of a winding might do it. The documentation mentions that the controller has current limiting to prevent demagnetizing permanent magnet motors, but provides no information on how to use the controller with PM motors. Usually, Universal motors are used where cost is a major factor, but when you try to control one, the controller, and if needed for CNC, the analog input and reversing options are fairly expensive. For CNC, it seems that you would save money by changing out the motor for a PM motor and PWM controller. Although, if you run the Universal on DC, it should act like and be controllable by a PM motor controller? Am I off base on any of this? - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Emc-users] Classicladder-modbus
I see your point Jeff though I don't see anything wrong with having classicladder support the modbus protocol. I am no where near finished adapting the new version (this is stretching my abilities!) so I don't know how modbus would be finalized but I visioned the actual calls to the ports as separate hal components ( there already is a serial port component I think). I agree that a totally separate modbus hal component gives the most flexability but even then the writing to ports should be separate components. I am thinking that getting modbus support in emc first is important and Classicladder has all the gui and code there. It could be pulled out and made into a separate component I suppose Chris Morley _ Introducing the City @ Live!
