Electronic Motor
Overload protec-
tion was acti-
vated.
Excessive RMS motor current according to the LM08
Electric Motor Protection overload curve or if the LM11
Peak Motor Current Factor is exceeded for more than 3
seconds for PM Synchronous Motors.
For induction motors the baseline current for Electric
Motor Protection corresponds to the LM09 Electric Motor
Overload Current.
For PM Synchronous Motors the baseline current for
Electric Motor Protection corresponds to the LM03 Motor
Current and the Peak Motor Current Factor is LM11.
Causes of excessive RMS current would be:
Incorrect motor data.
Verify motor data, specically the motor rated speed
and frequency relationship for PM Synchronous Mo-
tors (see Section 5.5.2, LM02 or LM04 for details).
Verify correct encoder settings including:
LE02 Encoder Pulse Number
LE03 Swap Encoder Channels (A/B setting)
LE06 Encoder Pole position for PM Synchronous
Motors. Relearn Encoder Pole Position as needed
(see Section 4.10.1 or 4.10.2).
High mechanical load/issues (friction).
