Cause
Spindle cable and spindle are OK,
and the spindle test is activated
> Spindle cable is too long
With activated spindle test, a test
current is send via spindle cable to the
spindle by applying a voltage at output
lines. In case that this current is too
low, or a wrong spindle characteristic
selected, it does not match to the
reference values and the spindle test
fails.
Spindle is at excess temperature
PTC in the spindle is defective
The PTC-wires within the spindle
cable are defective
Start via Analogue input is activated.
Set value for duty speed is too low
The selected spindle characteristic at
memory place xx is wrong, invalid or
corrupted.

Fixing
> Select correct spindle characteristic
> In the spindle characteristic the value of
the start voltage has to be increased.
-> contact BMR
Let it cool down
> Check, if the characteristic matches with
the spindle
change spindle
exchange cable or fix the connection
Deactivate Start via analogue input.
-> Manual: "Analogue Inputs"
and activate Digital Start
Increase Analogue value for duty value.
> A spindle start is carried out after reaching
the required minimum voltage according to
the scaling, only
> Select matching characteristic with the
