12.3 Alarm messages
About the object 6503h additionally to the EMCY-message further alarm messages
are output. The corresponding error bit is deleted, if the error is present no more.
Error
Cause
Remedy
Bit 0 = 1,
Position error
Failure of scanning elements
in the measuring system
Measuring system has
detected no magnet.
Slide magnet into measuring range.
Bit 12 = 1,
EEPROM error
Memory area in internal
EEPROM defective
Possibly shut-off measuring system voltage then
switch on again. If the error recurs despite this
measure, the measuring system must be replaced.
Bit 13 = 1,
Parameter error
Programmed parameter out of
range.
Check min. and max. values of each parameter.
12.4 Other faults
Fault
Cause
Remedy
Strong vibrations
Vibrations, impacts and shocks, e.g. on presses, are
dampened with "shock modules". If the error recurs despite
these measures, the measuring system must be replaced.
Electrical faults
EMC
Perhaps isolated flanges and couplings made of plastic help
against electrical faults, as well as cables with twisted pair
wires for data and supply. Shielding and wire routing must be
performed according to the respective field-bus system
construction guidelines.
Position skips
of the measuring
system
Extreme axial and
radial load on the shaft
or a defective
scanning unit.
Couplings prevent mechanical stress on the shaft. If the error
still occurs despite these measures, the measuring system
must be replaced.
