Commissioning Manual

Cause
Incorrect data of the absolute encoder.
The temperature of the control module
(Control Unit) has exceeded the specified
limit value.
The write access to the removable data
medium was unsuccessful.
The parameters of an individual drive
object were saved, although there is still
no backup of all drive system parameters.
The saved object-specific parameters are
not loaded the next time that the system
powers up.
For the system to successfully power up,
all of the parameters must have been
completely backed up.
An error was detected when evaluating the
parameter files saved in the non-volatile
memory. Because of this, under certain
circumstances, several of the saved pa-
rameter values were not able to be ac-
cepted.
Output data of Drive Bus master (set-
points) received at the incorrect instant in
time within the Drive Bus clock cycle.
There is no clock synchronization or clock
synchronous sign of life and DSC is se-
lected.
Note:
DSC: Dynamic Servo Control
The alarm threshold for overtemperature
at the inverter heat sink has been reached.
If the temperature of the heat sink in-
creases by an additional 5 K, then fault
F30004 is initiated.
Remedy
Contact the Hotline.
Check the air intake for the Control Unit.
•
Check the Control Unit fan.
•
Note:
The alarm automatically disappears after the
limit value has been undershot.
Remove and check the removable data medi-
um. Then run the data backup again.
Save all parameters.
Save the parameterization using the "SAVE"
function on the BOP. This overwrites the incor-
rect parameter files in the non-volatile memory
– and the alarm is withdrawn.
Check bus configuration.
•
Check parameters for clock cycle synchro-
•
nization (ensure To > Tdx).
Note:
To: Time of setpoint acceptance
•
Tdx: Data exchange time
•
Set clock synchronization across the bus con-
figuration and transfer clock synchronous sign-
of-life.
Check the following:
Is the surrounding air temperature within
•
the defined limit values?
Have the load conditions and the load duty
•
cycle been appropriately dimensioned?
Has the cooling failed?
•
