Troubleshooting
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
used,
- index pulse not connected,
- index pulse incorrect (all three channels must
have a simultaneous low), or
- 32-01 Incremental Resolution (ENCODER) is set too
low.
Error 110
Unknown command
Cause is a Communication or program error. The program
must be re-compiled and re-loaded.

Software end limit
A motion command will cause or has caused the software
end limit to be activated.
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 a new error
is generated.
Handling of hardware limit switches is the same as
software limit switches. That means that the error you can
clear and drive in the opposite direction. But if you try to
move in the wrong direction, then the error 198 occurs.
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 frequency
converter must be manually moved back to within the
admissible area, or the monitoring of the software limit
switch must be temporarily de-activated via 33-43 Negative
Software End Limit Active and 33-44 Positive Software End
Limit Active. Only then is it possible to clear the error.
Limit switches and reference switches allow the usage of
any input. That means not only 1..8 are supported but also
larger numbers as well as virtual inputs or outputs.

MCO 305 Operating Instructions
NOTE
Using virtual inputs as limit switches is dangerous because
it eliminates the direct connection between the limit
switch and the controller. That may introduce a time delay
(or other failure scenarios) which will limit the controller's
ability to respond quickly to the switch. Software-limit
error handling a up MCO 5.00:
A Software-Limit error can not be cleared: The control unit
will be switched off and the frequency converter must be
manually moved back to within the admissible area, or the
monitoring of the software limit switch must be
temporarily de-activated in 33-43 Negative Software End
Limit Active and 33-44 Positive Software End Limit Active.
Only then is it possible to clear the error.
Error 112
Unknown parameter
An attempt has been made to change a parameter (SET or
SETVLT command), which does not exist.
Error 113
FC not enabled
VLT Error Status: VLT AutomationDrive is not ready but the
PID controller is active. The FC status word (Bit 09 and Bit
11) is monitored every 20ms when the PID controller is
active. The VLT AutomationDrive is in the "Not ready" state
when:

Error 114
Too many loops
Too many nested LOOP commands exist in the executed
program.
Error 115
Parameter save failed
The INLONG command got an illegal string. It has been
used to read a long value from serial line. If the string
which arrives does not represent a valid number then this
error will be released.
Error 116
Parameters memory are corrupted
The parameters in EPROM are no longer correct because of
-
-
NOTE
Re-initialize the parameter with 14-22 Operation Mode and
then overwrite these parameters again with your own
application parameters. Otherwise motion programs which
require application parameters will no longer function
correctly.
In Stand-alone-Mode you could also use Controller →
Parameters →Reset.
