The converter isn't
found during
initialization of the
Windows program
When using a laptop the voltage levels sometimes are too
low. There are external boxes to boost this levels to the
normalized values. Be sure to use a zero-modem cable
During initialization the converter has to be turned on.
Don't use cables longer than 2m
The LED shows "Spindle
not ready"
Check whether the PTC in the spindle has a fault or is broken.
Is the PTC connected properly ?(see chapter 9 examples) Is
the spindle connected properly ?
(see chapter 9 examples)
The LED shows
"converter not ready"
Is overtemp. converter active (check fan...)
The hardware switch has gone off- error reset via start, after
release check whether spindle has blocked before re-starting
the spindle. The normal current overload protection has
tripped- re-start possible via start button or dig. pin eg. A dig.
pin (emergency stop or power stage off) is still active- check
the inputs. Check whether the right spindle diagram is
chosen.
When the hall sensor is active, but the hardware input is
floating, error spikes prevent the spindle from starting- check
the wiring of the hall sensor.
The spindle doesn't
start in spite of
"converter and spindle
ready"
If one analogue input is released for external speed control,
the spindle will start above the minimum required voltage
level which corresponds to the min. speed set by the
diagram. Also the dig. input Start pin has to be activated in
parallel.
When the green "start" LED appears, it could be that the
motor cable has been put out after the self-test procedure
