Signal Checking Setup
The DP1200 has the facility to detect if the encoder attached to the 4th digital axis has become
disconnected, sustained severe cable damage, or with some encoders, experienced electronic failure.

Mode of Operation
The detection mechanism monitors the incoming signals from the encoder to look for an illegal
combination of input levels.
If the encoder becomes disconnected, then the illegal
input combination is generated internally within the
DP1200. The display will then show ‘SIG FAIL’. If it is
possible to correct the fault, press the axis zero key to
reset that display. If the ‘SIG FAIL’ message continues
to be displayed then the fault has not been corrected.

X = any state i.e can be either high (H) or low (L).
Note:
Please check the encoder specification for information on the synchronisation of the index
marker pulse. If the encoder is capable of generating the illegal condition (A low, B low and RM high),
then signal checking function should be
TURNED OFF
