Dan,
This is part of a program use to control a mimimover robot witch looks
a lot like the teachmover.
It was written by my father centuries ago ... =)
I think it's written in Modula-2 and contains the kinematic equations
you'll need.
Regards, Jan

Sorry guys for using the list for something not really related to EMC, but I
do know here are a lot of people with the knowledge I need.
It was long time ago I designed something with electronics, so I hope
someone can help me.
What I need is an electric braker-pusher. It will not need to come to
google for regenerative braking as used in vehicles

Does it have to be two function i.e brake - push or does it need to
produce a constant force? Constant force can be very easily achieved
with a torque mode servo drive or even a simple constant current circuit
driving a motor.

It's either pushing or braking according to the given value, but the value
will change over time. It's going to be a part of a simulator where the
program will simulate a road, so it's uphill or downhill.

Back when computers where not the norm, the company I worked with made a road
load function generator. It worked in conjunction with a motor and a gearbox to
couple a eddy current brake. The brake had the road load function generator as
its input. The generator really was just a Y=aV^2+bV+c
DC applied to an AC motor will slow the motor down and stop it...
dunno if this helps but it is an old technique for braking.

No problem, i'll try 2.2.8 but... was the same about 2.2.7... i was
using 2.2.6 and you told about going to 2.2.7, and i went, so... should
i guess 2.2.7 is not ready...¿?
I mean... if it is supposed to work in a version, why should i always go
next version to make at least a try?. and this

Generally speaking it won't stop it dead because it has to turn to generate
the braking force currents in the always shorted armature of an AC induction
motor. This force can be

Some of the new drives have the capabilities that you are looking for built in.
I was just hearing the other day about a Siemens drive that is even line power
regenerative-when the motor is being

Can't we run an AC servo in a + or - torque mode, based on a + or - control
voltage applied to the servo drive? Clockwise rotation (torque force) for + and
CCW for a - control voltage. The servo tries to maintain a commanded torque
output. Forcing the motor shaft to rotate. I would think DC

So as not to let this thread die off with no outcome reported, I did get
the toolchanger running again by using %IW instead of %W for the tool
prep number.
One issue here is that the Vars button doesn't show these new
variables. Probably a third window is needed after bit vars and
internal word
It's absolutely a cost issue, and the servo drives are way to exotic for
this project. I only need a small motor that just drives or brakes according
to the rate that the computer sent. I had an idea of letting a thyristor
shopping up the frequency, but it would be much easier to run a DC motor

That has been fixed AFAIK. In older versions you could use the vertical
connector tool and
click again on a bar and it would erase it.

I use the vertical bar to remove itself because the eraser can't sense
the vertical. These icons are press on press off.
