If the thermal model reaches
the warning level a warning is
generated.

Locked Rotor
40 Locked rotor
trip level
Current in percentage that
should trigger a locked rotor
fault during motor start-up. A
value of 800% (160) switches
off the function.
100% ... 800% in steps of 5%
800% disables the function
Unscaled: 20 ... 160
Example: 100 means 500%
All
41 Locked rotor
trip delay
The time the motor current
must exceed the adjusted
threshold before a fault is trig-
gered.
0, 0.1, 0.2, 0.3, 0.4, 0.5 ... 25.5s
in steps of 0.1s
Unscaled: 0...255
Example: 5 means 500ms

Phases
42 Phase loss
protection
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.
Off (0), On (1)
Note: If the voltage module is present
this parameter activates both voltage and
current based phase loss detection.
All
43 Curr Imb Trip
Level
Phase imbalance (current) trip
threshold. Above this value a
trip is generated. A value of 100
disables the trip.
0...100%
100% disables the function
Default value: 50

44 Curr Imb
Warn Level
Phase imbalance (current)
warning threshold. Above this
value a warning is generated.
A value of 100 disables the
warning.
0...100%
100% disables the function

45 Phase
reversal
If enabled the three phases
must be fed through the UMC
CTs in the correct order (L1 left,
L2 middle, L3 right).
L1L2L3 (0),
L3L2L1 (1)
Note: If the voltage module is present
this parameter must not be changed.

46 Check phase
sequence
Enables supervision of phase
sequence (L1/L2/L3)
Disabled (0),
Trip (1),
Warning (2)
Note: If the voltage module is present
this parameter activates both voltage and
current based phase sequence protection.
