What got me thinking here, (new experience!) is that in this case if they change a tool halfway through the file and the motors have reduced torque due to...
Motor current is restored nearly instantly. Assume a 5mH motor coil, a 50VDC power supply voltage and a 5A per phase current set: Current will be restored at a...
Mariss, I would then assume that a reasonable acceleration scheme ( straight-line or S curve) will bring the motion to a prescribed feed rate. As long as that ...
Dhiren, The electrical time constant is about two orders of magnitude less than the mechanical time constant meaning phase current restoration time after...
Hello, Another question concerning heatsinking 202's, you specify that a heatsink is not required for less than 6A, is this 6A continuous or assuming that some...
Please always use a heatsink if you can. At 6A the case temperature reaches 75C or 167F and is the max rated temperature for the drive. This is something I'm...
Mariss At one stage you were developing a brushless drive IIRC. Is this on hold? I'm currently looking for something to drive some Mitsubishi servos. Also...
I have a brushless prototype but haven't done anything with it for about 3 years. I was not happy with the 3-4 encoder count "tick" it had every 60 mechanical...
Well, I've waited patiently until the announced Sept 1 release date. How can one place an order for a G101+G102 so that we can get on with our R&D development...
It probably will survive (I regularly do that myself) but no claim is made in the manual that it will. Mariss ... up? ... less ... perhaps my ... new...
Hello, Is it possible that with the drive at a high temperature that it could miss steps? I know that the frequency response of the logic is inversely ...
Unlikely in the extreme. The device AC specifications for a given Vcc are specified at the maximum rated temperature. More likely was some bad connection...
Mariss, You posted a circuit on the CCED list a while ago that allows the use of an analog encoder with sinusoidal output to be converted to a TTL level...
I have in the past built a 4 axis foam cutter with hobbycnc board. So I have a little experience in doing this stuff. My intensions are to build a 5 axis...
Hello Mariss, What is the latest on the stand alone (PLC like) operation? I've got a few applications that require simple, repetitive motion control. Like a...
The G101 and G102 are stand-ins for the G100. The G100 is a G101 plus a G102. I really hate model numbers particularly when most people don't know what they...
... Mariss, What current percentage of sales are to hobbiests and squirrels as opposed to OEM's? I would think that non-OEM's (like me) would prefer the G100....
Thanks for the info Mariss, Does the G100 and G101 come with a Rabbit microprocessor? I assume it is integral to the G-Rex's operation, but at some point it ...
... I was thinking that as well. As a DIY with machining and CNC background, having a ready made device that's ready to be wired in easily is high on the list....
ok, now I'm a bit confused by terminology. You refer to the G101/102 then also to the G-101 G-Rex. As I understand it, the G101 is used as a smart step...
The G101 ships without a Rabbit MCU core module. The reason is presently there are 5 Rabbit Semiconductor modules that fit the G101; the RCM3600, RCM3610,...
Ted I understand your confusion. If your statement 'All require the addition of stepper power drivers that accept step/ direction control and power supply,...
Sort of correct. The 'G-Rex' is the stripped down G101 available now and the soon available G100. Both are identical except the G100 will have terminal blocks...
