Error 103
Illegal axis number
A motion command is addressing an axis number
greater than 1.
Error 105
Error not reset
An attempt has been made to execute a motion
command, although an actual error message has
not been cleared.
First clear the error message and then execute the
motion command.
Error 106
HOME not done
Failed to move to HOME position. According to the
axis par. 33-00 Force HOME, a forced move to the
machine zero-point is demanded, before other
motion commands can be executed. This move to
the machine zero-point has not been executed.
Error 107
Home velocity zero
An attempt was made to execute the HOME
command but the motor is set to 0 in par. 33-03
Velocity of Home Motion.
Error 108
Position error
The distance between the set and the real position
was greater than the Maximum Tolerated Position
Error defined in par. 32-67.
Causes:
− Mechanically blocked or overloaded drive,
− par. 32-67 Max. Tolerated Position Error too
small,
− commanded speed greater than FC 300 para-
meters 4-13 Motor Speed High Limit and 3-03
Maximum Reference,
− commanded acceleration too great,
− par. 32-60 Proportional Factor too small, or
− FC 300 not enabled.

Error 109
Index not found
At reference or index search, the encoder index
pulse could not be found within a motor rotation.
Causes
− An encoder without an index pulse has been
− index pulse not connected,
− index pulse incorrect (all three channels must
− the par. 32-01 Incremental Resolution
Error 110
Unknown command
A communication or program error. The program
must be re-compiled and re-loaded.
Error 111
Software end limit
A motion command will cause or has caused the
software end limit to be activated. These limit are
activated if actual or target position is outside
software limits specified by parameters Negative
and Positive Software End Limit 33-43 and 33-44.
Identification of attainment of software limit at a
motion in the speed mode will only be made after
the current position is identical to the software limit
switch.
Starting with MCO 5.00 it is possible to clear a
software limit error and then drive in the opposite
direction. If you try again to move in the wrong
direction, then error 198 occurs.
Handling of hardware limit switches is the same.
In positioning mode, it is known before motion
start that the target position lies outside the path.
In this case, the movement will not be executed
and the error message can be cleared.
The control unit will be switched off and the drive
must be manually moved back to within the admis-
sible area, or the monitoring of the software limit
switch must be temporarily de-activated via the
Negative and Positive Software End Limit in para-
meters 33-43 and 33-44. Only then is it possible to
clear the error.
Limit switches and reference switches allow the
usage of any input, that means also larger
numbers
