- A motor always turns in the wrong direction
The
Dir
signal is not carried to the power stage. Please check that this signal is
not swapped with one of another axis, and th at the ground is well connected to
the
Dir
input (or
Direction
, or
Sense
) of the corresponding power stage.
- An axis makes its reference run toward the wrong direction
If the motion is fast, then the axis is completely inverted an dits direction must
be changed from Galaad parameters or from the power stage or from the
motor. On the other hand, if the motion is slow, then probably the zero-end
switch input is wrongly set,
i.e.
the corresponding input is not the right one or its
polarity is reversed. Then the software tries to release the axis from the switch
though it is not triggered. It is important to find the right nu mbers and polarities
for the inputs that correspond to the end switches. If you are using Galaad
software, then check the function
"Parameters / Machine / I-O test"
as previ-
ously described.
- The axis does not stop during the reference run
The input that actually corre sponds to the zero-end switch is not the one that
has been parametered, or the switch is not working, or is not triggered by the
axis, or the connection wire is cut or unplugged.
- The spindle does not start
The power relay corresponds to the output # 5. Please check that this is the
actual output in the software. If the spindle is under control of the PWM output
or the 0-10 V analog output (associated to the PWM), then check that this has
been accurately set and calibrated in the software.
