MCO 305 Design Guide
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 drive must
be manually moved back to within the admissible
area, or the monitoring of the software limit switch
must be temporarily de-activated the Negative and
Positive Software End Limit in parameters 33-43 and
33-44. 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: FC 300 is not enabled but the PID
controller MCO 305is 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,
– or par. 8-02 Control word source is not set to
Option C0.
Error 114
Too many loops
Too many nested LOOP commands exist in the
executed program.
Error 115
Parameter save failed
Saving of the option parameter 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
– EPROM defective or
– power outage while saving.
NB!:
You must re-initialize the parameter with
a 14-22 Reset and then overwrite these
parameters again with your own
application parameters.
__ Troubleshooting __
Otherwise motion programs which require applica-
tion parameters will no longer function correctly.
In APOSS stand-alone you also could use Controller
→ Parameters → Reset.
Error 117
Programs in memory are corrupted
The program data stored in EPROM cannot be
found or are no longer correct because of
– EPROM defective or
– power outage while saving.
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 Reset → Complete in the
APOSS menu Controller.
In APOSS stand-alone delete the EPROM with
Controller → Memory → Delete EPROM and then re-
load the programs and parameters.
Error 118
Reset by CPU
The processor has been stopped and a re-set has
automatically been executed (watchdog).
Causes could be
− Short term voltage drop,
− voltage peak, or
− short circuit.
Error 119
User abort
The Autostart program has been aborted by the
user.
Or the [CANCEL] key was pressed during switching
on and a Master Reset triggered.
Error 121
No more SDO channels
If a SDOREAD or SDOWRITE is used with a nega-
tive index, then the command returns immediately
and stores the running SDO in a channel. It is freed
when the result is read.
There is a maximum of 5 channels.
