Hi Andrey
There has to be a reasen why the motor overheats. It's either mechanically or
electrically.
If you can eliminate electrical sources (amp matches motor, weired accelerations
or vibrations) then there should be mechanical ones.
Did you disassemble the broken motor to find out why it
Hi Ulf. Thanks for your answer.
I think, that the reason is electric here.
I disassembled the broken motor, also have found out that windings
And lamellas of the motor are serviceable. I have seen that on windings of the
engine there was an over current because isolation of crosspieces between
What condition are the bearings in? Is it possible that the motor
mounts are misaligned, leading to excessive bearing wear, and hence
motor stiffness?
Hi Andy.
Motor mounts and bearings are in good condition, because all these parts new.
The mechanics is completely identical on axes X and Y, but

Hi S,
The pluto-step author says it worked for him to run a 3 axis
I originally developed the fpga firmware and hal driver for pluto-p, but
I no longer develop them. I don't even have a PC capable of running
the development environment for the FPGA anymore.
I do not recommend pluto-p for new users to purchase. The Mesa
Electronics and Pico Systems FPGA cards
Thanks for the replys Guys! :-)
That would explain things.
I was using the debug print commands and when moving the Y axis with 3 axis
enabled I was getting a different number return on PPDATA then I was with
the Z and X which were the same.
Z, X returned 64511 and so did Y positive move.

Jeff,
I can remember discussing with you the pluto-p a few years back on EMC IRC
channel. BTW do you get on there much these days?
As a sugestion it may be wise to have a caveat explaining the short comming

Andrey,
If you do not have a circuit breaker on the wiring to the servo motor you
should put one in. At least on the axis that is burning the motor. You would
eliminate the burned motors and still be alerted to the motor heating
problem as the circuit breaker would trip.
This should allow you

Hi! All thanks for answers. I can make some explanatories to this problem.
Milling mashine has 3 axes. The motor on axis Y Fails only.
All of axes have identical servoamplifiers and motors.
The motor on axis Y does not vibrate and does not rustle, all 3 axes have
identical PID

An option is to try a light bulb in series with the motor. Eg With 24 volt

the bulbs light up and reduce the power to it to a 1/4. Under low load, the
bulb is a low resistance and all should run well, under high load

I have been busy setting up the USC for a servo system and just

I am sure I could take the time to study the USC device description and
