Cause
The maximum permissible number of er-
rors in the controller sign-of-life (clock
synchronous operation) has been exceed-
ed in cyclic operation.
Motor overloaded
•
Motor surrounding temperature too
•
high
Wire breakage or sensor not connected
•
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 upper torque limit is lower than the
lower torque limit.
12.2 List of faults and alarms
Remedy
Physically check the bus (cables, con-
•
nectors, terminating resistor, shielding,
etc).
Correct the interconnection of the control-
•
ler sign-of-life.
Check whether the controller correctly
•
sends the sign-of-life (e.g. create a trace
with STW2.12...STW2.15 and trigger sig-
nal ZSW1.3).
Check the permissible telegram failure
•
rate (p0925).
Check the bus and controller for utilization
•
level (e.g. bus cycle time was set too
short).
Reduce the motor load.
•
Check the surrounding 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.
The upper torque limit (p29050) must be ≥
lower torque limit (p29051)
