Now you must setup the internal data of the
PulseMaker
card. Still in this
"Controller"
page of Galaad machine parameters, click on the small button
"

at top-right aside the controller type. This pops up a sub -window that
provides access to all special parameters for your card.
The
status of outputs
at boot
allows you to
enable some output as
soon as the card is
powered on, before it is
communicating with
Galaad, for example to
trigger a safety device
or the power stage.
The parameters for
Start/Stop frequency
and the
acceleration
depend on the mecha-
nical characteristics of
your machine (inertia,
motor power, axis
reductions). So it is not
possible to indicate
standard values here. You must try different settings. Let us say at least that
the Start/Stop frequency is the initial starting speed of the motor (instant pass-
ing from still to motion and reciprocally). If your motor "knocks" when starting to
move, then you should reduce the value. On the other hand, if the acceleration
starts from too low, you must increase it. The acceleration indicates the speed
slope, from the Start/Stop frequency. If your motor is unable to drag up the
speed, then reduce the value. If the acceleration is too soft, increase it.
The
enable signal from power stage
says on which input the information is
received for knowing if the power stage is ready. If not, Galaad will warn the
user to power-on the stage. The
current per phase
is for power stages with
digital potentiometers (AxeMotion option) so you can set the current directly
from Galaad. If you do not have such connecti on, this parameter is useless.
The
error or stop signal
defines a critical input that will stop the motion and
abort the automatic process when triggered. That can be for example the
Drag
Error
bit of a servodrive.
