In order to protect the motors against thermal destruction in the case of
peak loads occurring for a very short time, the thermal work load of the
motor is continuously calculated in the controller by means of a motor
temperature model.
If the maximum possible motor current is reduced, due to the current
thermal motor load, compared to the content of
S-0-0109, Motor peak
current
, the drive generated the warning E8055. As a consequence
thereof the drive can no longer follow the command values preset by a
control unit.
Note:
When the E8055 warning is active, bit 0 (overload warning) is
additionally set in
S-0-0012, Class 2 diagnostics
.
Cause
Remedy
Too high acceleration torque/too high acceleration
force demanded
Reduce acceleration by adjusted command value profile
Overload of drive by too high continuous load
Reduce overload in the case of long machining phases
Too high process or machining force (e.g. infeed)
Reduce process or machining force
Mechanical changes in axis (e.g. friction, load
conditions,...)
Check mechanical system and, if necessary, optimize
load conditions and/or friction conditions
