Index Adjustment
The encoder index position in the module is out of adjustment.
During initialization, the first piston is moved to the mechanical stop. After
reaching the mechanical stop, the piston reverses direction until the encoder
index position is reached. If the time to reach the index position is too long,
the error message is generated.
Index Missing
The encoder index position in the module was not found during initialization.
During initialization, the first piston is moved to the mechanical stop. After
reaching the mechanical stop, the piston reverses direction until the encoder
index position is reached. If the index position is not recognized within a
defined time, the error message is generated.
