MCO 305 Operating Instructions
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
the par. 32-01 Incremental Resolution
(ENCODER) is set too low.
Error 110
Unknown comm.
Cause is a Communication or program error. The
program must be re-compiled and re-loaded.
Error 111
SW 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.
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 par.
33-43 SWNEGLIMACT and par. 33-44
SWPOSLIMACT. Only then is it possible to clear the
error.
In positioning mode, it will be 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.
Error 112
Unknown param.
An attempt has been made to change a parameter
(SET or SETVLT command), which does not exist.

Error 113
FC not enabled
FC 300 is not ready but the PID controller is active.
The FC status word (Bit 09 and Bit 11) is monitored
every 20 ms when the PID controller is active. The
FC 300 is in the "Not ready" state when:
– it has an alarm,
– it is in local mode,
– local LCP stop is activated.
Error 114
Too many loops
Too many nested loops exist in the executed
program.
Error 115
Par. Save failed
Saving of the option parameter failed.

Otherwise motion programs which require
application parameters will no longer function
correctly.

You have to do a 3-finger reset to reset all parame-
ters to their defaults (ex factory) and to delete all
user programs, arrays, and application parameters.
Afterwards re-load the programs and parameters.
This corresponds to a
APOSS menu.
