HALT
COMPR CORRELA-
TION ERROR
The is a Correlation Error. In case signals from abso-
lute coder (potentiometer) and coding wheel (motor
encoder) are not correlated.
See
JC DIAG A1205 COMPRESSION CONTROL
to fix the problem.

HALT
COMPRESSION
MOTOR STEP
LOST
Occurs when a difference is detected between the
number of steps commanded and the number of
steps detected by absolute encoder. This can hap-
pen whereas correlation is OK, for example when a
mechanical hardpoint imposes zero signal from both
encoder and potentiometer.
See
JC DIAG A1206 COMPRESSION CONTROL
to fix the problem.

HALT
COMPRESSION-
OVERSPEED
The compression speed measured by the encoder is
too high in relation to the speed profile (and correla-
tion is OK).
See
JC DIAG A1206 COMPRESSION CONTROL
to fix the problem.

OVERCURRENT
Occurs when an integrated value of the current is too
