Description, Explanations
If the thermal model reaches
the warning level a warning is
generated.
Current in percentage that
should trigger a locked rotor
fault during motor start-up. A
value of 800% (160) switches
off the function.
The time the motor current
must exceed the adjusted
threshold before a fault is trig-
gered.
Trips the motor depending of
the trip class within 1.5 -12
seconds in case of a phase
loss. This parameter must be
set to On during regular opera-
tion.
Phase imbalance (current) trip
threshold. Above this value a
trip is generated. A value of 100
disables the trip.
Phase imbalance (current)
warning threshold. Above this
value a warning is generated.
A value of 100 disables the
warning.
If enabled the three phases
must be fed through the UMC
CTs in the correct order (L1 left,
L2 middle, L3 right).
Enables supervision of phase
sequence (L1/L2/L3)

Off (0), On (1)
Note: If the voltage module is present
this parameter activates both voltage and
current based phase loss detection.

100% disables the function
Default value: 50

100% disables the function
L1L2L3 (0),
L3L2L1 (1)
Note: If the voltage module is present
this parameter must not be changed.
Disabled (0),
Trip (1),
Warning (2)
Note: If the voltage module is present
this parameter activates both voltage and
current based phase sequence protection.
