order: here you will find additional notes on possible
causes of errors as well as tips for clearing errors.
O.ERR_5

An attempt was made to execute a command to
move, although an existing error message had not
been erased.

Position error
Meaning
The interval between the reference position and the
feedback position was greater than defined in
Tolerated Position Error Parameter.
Causes
Mechanically blocked or overloaded drive, tolerated
position error too small, reference speed greater than
VLT Parameters 202 and 205, reference acceleration
too great,
Proportional factor too low or VLT not released.
O.ERR_9
Index pulse (encoder) not found
Meaning
During a reference or index search, the encoder
index pulse could not be found within one encoder
rotation.
Causes
A encoder without an index pulse is being used, the
