Hi,

Is it tricky to set up the motors through the PC

The servodrive and servo are a closed loop. Thus any step/direction controller will have no difficulty in commanding these servos.
Mach4, UCCNC, Centroid and LinuxCNC are all worthy contenders.

Ok,
So just to clear things, as am a dummy when it comes to servo,
Am well experienced in steppers,

The controller I will be going for is not pc based, but has step dir output control.
So do these motors have to be setup through a PC to set the speeds/ tuning, or does that be done on the servo driver,
Or does it be done on the CNC controller, just like you would setup steppers on the like of Mach3,

Regards Gary

Hi,
modern AC servos have a programmable drive. There are a lot of parameters to set. In most cases you can set them by pushing buttons on the drive
like programming a watch, but its a real PITA and mistake prone. Most manufactures offer software assistance that resides on a PC by which you program
the drive. Once the drive is programmed to your satisfaction you can install it in your machine without the need of a PC. Programming drives with a PC is highly
recommended.

The only 2D standalone Step/Direction plasma controllers that I've had anything to do with are cheap Chinese ARM based units. One customer had several, all of them
blew up eventually and the standalone THC controllers blew up regularly. In the end I convinced him to go for Mach4, a Hicon motion controller with realtime THC
control and he hasn't looked back. Now Mach4 has a script based THC feature which as far as I'm concerned leaves those cheap and nasty ARM controllers
for dead.

As for the Fanuc/Seimens type controllers, well the sky is the limit, I hope you have plenty of money, you'll need it if you want a good industrial control.

So do these motors have to be setup through a PC to set the speeds/ tuning, or does that be done on the servo driver,
Or does it be done on the CNC controller, just like you would setup steppers on the like of Mach3,

Both. In the servodrive you will program absolute max accelerations, velocities, voltages, currents and more. Then in the controller you will have to
program desired max accelerations and velocities, at least a little less than you have programmed into the drive. It doesn't matter whether the controller
is a PC type or an industrial standalone type you will have to program it with these parameters.

Ok thanks Craig,
Hopefully Mach 4 is better that the Mach 3 I was running,
It kept lossing steps, and would take the odd idea of running a straight cut of the parts already cut.

Hi,

Mach3 is no more prone to losing steps than Mach4. Losing steps is a classic symptom of stepper overload and no software will
prevent the laws of physics from taking its toll.

Having said that Mach4 does have a much more comprehensive suite of features for plasma tables, including a script based THC solution. It is the only
Windows based CNC solution that does so, all the others require realtime hardware which is supervised by the Window app.

The script based THC has a very modest bandwidth of around 20Hz, so any system that demands HIGHLY compliant THC will not be satisfied with Mach4's
script based solution. There are two manufacturers of external motion control boards suitable for Mach4 which support realtime THC, the Hicon Integra and the
Ethernet SmoothStepper. The Ethernet SmoothStepper in particular is matched to TMC3in1 plasma THC controller.


With Mach4 then you have four alternatives to enact THC:
1)Use a Proma Voltage detection unit feeding Machs script based THC (note the bandwidth limitations)
2)Use a TMC3in1 unit and an Ethernet SmoothStepper for a highly compliant fully featured THC solution
3)Use a Proma unit and a Hicon Integra which also offers realtime THC and a nice feature set albeit somewhat reduced from the TMC3in1
4)Use a completely stand alone THC controller that manages the Z axis entire. Cheap Chinese controllers of this description blow up regularly. Good ones like
Hypertherm cost a fortune.

Hi,Craig

Did you find them B2 servo drivers hard to wire,
There seems to be alot of pins on the port going back to the controller, maybe 40!
Are they all used,
I would have thought 4 pins is defo needed for
The control of direction for+- etc
And maybe some pins for axis limits, emergency stop etc

But I didn't think all them pins need to be used
????

Hi Craig, I bought 4 servo drive and motor from Fast to buy (no name and no information ) , as a nerd in servo I find my self in a dark room with on light around .I'm at the point where my drive are ready to receive code or information but to much confusion and no information around.
Where to start ?
what to use as step/dir for motion on controler card .
Programming servo , noname compagny don't have software to offer , so what to use ?
Can you give me/us some information or place to go for info .
Thanks.

Hi,
without setup and tuning software you'll have to program it by hand, that is, push buttons on the drive to program all the required
parameters.

Post the manual.

Hi Craig, My setup is 5 (1524mm) x 10(3048mm) feet and all ball screw y 4010 and x 2510 and z 1604 . 4 ac servo drive 1kw the 90st-04025 toauto fasttobuy . the technical that I know are very limited . that is why I will upload the manuel . Win 10 , mach4 hobby ,hardware controller card BM3 (cncroom) smooth stepper ethernet .My z cable is to short so I tried to make a extension but it not working the drive goes to alarm at the first command . You said that only 4 wires is need for making the drive usable in my case can you tell me wich one is needed.
As you mention that is a pain in the ..... to program manualy I try to firnd software but can't find one . As a new servo user I seek for information to performe a good installation .

Hi. What can we do, if on AMADA AE255nt (fanuc) appears alarms about servo system? code: 306. We changed all baterries. Not result.

Hi all,
we are using ASD-A2-E for a gantry robot and there is a problem in limitation of torque posing on servo motors. in ASD-A2-E manual there is no Torque limitation parameter. how can adjust servo drive in order to eliminate overrated toque on motors.
also, i have a another issue that there is huge delay before starting new position
