■ SyncPos option messages in detail
As in the table above, the messages are in numeri-
cal order. Here you can find additional information
about possible causes and tips on troubleshooting.
O.ERR_3
SyncPos
Axis no. %bu not in system
Cause
An attempt has been made to find another axis
which does not exist in the controller. (The program
allows for input of axis numbers greater than 1
since it is configured for multi-axes applications.)
Tip
Check to see if the program axis command has an
invalid number or a general axis command (...X(*)).
O.ERR_5
SyncPos
Axis no: 1 - Error not cleared
Cause
An attempt has been made to execute a motion
command, although a momentary error message
has not been cleared.
O.ERR_6
SyncPos
Axis no: 1 - Failed to move to HOME position
Cause
According to the axis parameter HOME_FORCE
(3), a forced move to the machine zero-point is de-
manded, before other motion commands can be
executed. This move to the machine zero-point has
not been executed.
O.ERR_7
SyncPos
Axis no: 1 - Home vel 0
Cause
HOME was executed with HOME_VEL set to zero.

O.ERR_9
SyncPos
Axis no: 1 - Index pulse (encoder) not found
Meaning
At reference resp. index search, the encoder index
pulse could not be found within a motor rotation.
Cause
An encoder without an index pulse has been used,
index pulse not connected correct,
index pulse incorrect (all three channels must have
a simultaneous low) or
the parameter ENCODER (2) is set too low.
O.ERR_10
SyncPos
Unknown command
Cause
A communication or program error.
Tip
The program must be re-compiled and re-loaded.
