Mariss, If (When) I connect a servo/g320 to the Grex to eliminate following error on acceleration will it be as simple as just jumpering the encoder a/b phases...
I've never done steppers but I think so. I used an E3 encoder on a large motor and several of their S5S with G320's. Make sure you get the alignment tool. ...
I'm looking at the E6S-500-500-IHT-PKG3 encoder, a CA-3132-1FT cable, and several CON-FC5-22 connectors for a PK299-F4.5B motor. The encoder has 500CPR to give...
... These encoders typically accept up to 0.01" axial shaft play - is that enough? My limited experience with Vexta PK299 series tells me I can feel axial play...
The only motor that I have right now with an encoder mounted is a servo. The PK299-F4.5B stepper motor was shipped today. When it arrives later this week,...
... his design goal and your design goal, you would hold all motors to tight synchronization, but MachIV might let things get sloppy - in my case, with the...
Art, My apologies. I should be more patient. When I bought the G101/G102 components I knew that it would be months, or more, before that particular 'system'...
... Have you figured a way to dust-proof the point where the shaft exits? (realising that the shaft also has two flat faces). I would be tempted to simply cut...
I've been watching on and off all day hoping that someone had already solved the problem. My plan is to buy/make a 'cup' that fits over the end of the motor...
Tom & Mariss, Not sure where my latest problem is thus a duplicate post. I went to fire up the torch today (Tom - relay K4, old sensor card w/ clear coats -...
Would it be possible that there will be Unstallable servo motor? If there is overload, the servo motor will be slowing down to the corresponding load. Fortino ...
1) I have no idea what a MP1000 is. 2) Voltmeter readings on the motor outputs are meaningless. 3) Give me a call tomorrow. I can't make sense of this. Mariss...
Mariss, I'm thinking it's either my mistake on a setting w/ Mach 3 or a problem w/ MP1000 - Torch Height Control Tom Caudle & Company. CandCNC.com - as...
... I think that the only issue is the shaft length - my impression is that the rest of the encoder is already inherently dust-proof and tough enough for light...
Unlikely, Servo motors deliver their max torque at high speeds, as a matter of fact the torque curve is almost flat I think, so no point on slowing it down,...
Although the servo motor would not develop more torque if slowed down, the cut would require less torque if the move speed were slower; therefore, whether more...
Yes that's true, it's just that the effect is more useful with steppers running above their critical speed. The concept of slowing down when overloaded is...
... Yes, but there's another problem. The tradidional method of controlling a servo is with a PID loop. Compare actaul position to commanded position, and...
There is a direct path and that is the following error. This is available in Steve's axis lead/lag register. A servo that develops an increasing following...
The PK299-F4.5B motor just arrived. With no power to the motor, there is 0.015-inch axial play. Whether there will be that much play under power will have to...
... Hi Use a proper industrial encoder with ballraces and a decent coupling, and you dont have to worry about it. Only drawback is the increase in overall...
I think that I'm having a little problem. From the time that I started looking at Gecko/Mach/other hardware and software, I've never tried to find the...
... You can get shaft mounted encoders with integral bearings that sit on a flexing spring mount. Example: http://www.dynapar.biz/h20.htm But, those things...
... ?!? Seems I woke up in the wrong universe this morning. Hate when that happens. For a constant supply voltage, the torque available from a PMDC servo is...
True enough if the motor had no heat dissipation. This dissipation is almost entirely I^2 * R heating of the armature windings. The torque you speak of is...
This is true, but I don't see how that would apply to the subject at hand, unless you are suggesting that everyone should set the current limit on their servo...
... OK, but a servo amp doesn't supply "constant supply voltage". It supplies that voltage which its control algorithm determines will give minimum error....
Unrelated. It makes no difference to the G100 how the current limit is set. Prudence would dictate you wouldn't want to run a servomotor above it's continuous...
... proper supply ... loss ... This sorta is my point! IF you supply N amps you get X torque. But there is no controller in the world that supplies "amps"....
