Fault no. Eliminating faults Operating status
Offset fault in the static identification:
– Too little stiffness in the fixed stop
– Proportional directional control valve
defective
– External fluctuating force on the slide
during identification travel
S Ensure stiffness of the fixed stop
(e.g. remove cushioning plate of
the DSMI-...)
S Replace proportional directional
control valve
S Use the constant external force
during identification travel
No movement during static identification or
reference travel S Check the compressed air supply
and the tubing
Overswing fault during dynamic identifica-
tion due to incorrect amplification stage,
cushioning stage or system parameter S Check and correct the amplifica-
tion stage, cushioning stage and
system parameter
Amplification stage, cushioning stage or
system parameter set incorrectly S Correct parameters
The measuring system has no valid length
code (non-permitted measuring system
length or length code does not exist) Servicing is required
SPC11 damaged (EEPROM-ACK fault) S Replace the SPC11
Measuring system type is not recognised
(invalid measuring system ID read in) S Replace the SPC11
Communication to measuring system is
faulty (non-plausible data has been
received) S Check the measuring system
length or replace the measuring
system
Communication to measuring system is
faulty (non-plausible data has been
received) S Check the measuring system
length or replace the measuring
system
Incorrect direction of movement ascertained
during positioning stroke; tubing is
incorrectly connected S Correct the tubing of the propor-
tional directional control valve
Allowed time exceeded; the position cannot
be reached fast enough (positioning timeout
approx. 10 s) S Remove obstruction in positioning
path or check compressed air
supply
