Commissioning Manual
6FC5397-4EP10-0BA8, 07/2018
Cause
The reception of setpoints from the Drive
Bus interface has been interrupted.
Bus connection interrupted.
•
Controller switched off.
•
Controller set into the STOP state.
•
The global control telegram to synchronize
the clock cycles has failed - in cyclic oper-
ation - for several Drive Bus clock cycles
or has violated the time grid specified in
the parameterizing telegram over several
consecutive Drive Bus clock cycles.
The maximum permissible number of
errors in the controller sign-of-life (clock
synchronous operation) has been exceed-
ed in cyclic operation.
Motor overloaded
•
Motor surrounding air temperature too
•
high
Wire breakage or sensor not connect-
•
ed
Motor temperature model incorrectly
•
parameterized
Open-loop/closed-loop control parameters
have had to be changed for the following
reasons:
As a result of other parameters, they
•
have exceeded the dynamic limits.
They cannot be used due to the fact
•
that the hardware detected not having
certain features.
The DC link voltage monitoring is active
and the lower DC link voltage threshold
was reached in the "Operation" state.
The DC link voltage monitoring is active
and the upper DC link voltage threshold
was reached in the "Operation" state.
Remedy
Restore the bus connection and set the con-
troller to RUN.
Check the physical bus configuration (ca-
•
ble, connector, Drive Bus terminator,
shielding, etc.).
Check whether communication was briefly
•
or permanently interrupted.
Check the bus and controller for utilization
•
level (e.g. bus cycle time was set too
short).
Physically check the bus (cables, connect-
•
ors, terminating resistor, shielding, etc.).
Correct the interconnection of the controller
•
sign-of-life.
Check whether the controller correctly
•
sends the sign-of-life.
Check the permissible telegram failure rate.
•
Check the bus and controller for utilization
•
level (e.g. bus cycle time was set too
short).
Reduce the motor load.
•
Check the surrounding air temperature and
•
the motor ventilation.
Check the wiring and the connection.
•
Check the motor temperature model pa-
•
rameters.
It is not necessary to change the parameters
as they have already been correctly limited.
Check the line supply voltage.
•
Check the infeed.
•
Reduce the lower DC link threshold.
•
Switch out (disable) the DC link voltage
•
monitoring.
Check the line supply voltage.
•
Check the infeed module or the brake
•
module.
Increase the upper DC link voltage thresh-
•
old.
Switch out (disable) the DC link voltage
•
monitoring.
