7-3
Loss of phase L1 x Option 1: Phase L1 missing, drops or fails while motor is running.
A trip occurs due to a voltage drop in the permissible rated operating voltage of >15 %
>100 ms during starting, or >200 ms in bypass operation.
Remedy: Connect L1 or rectify voltage drop.
Option 2: The connected motor is too small and the error message is issued immediately
after switching to bridging mode.
Remedy: Adjust rated operating current for connected motor or set to minimum (if motor
current is lower than 10 % of the configured I
e
, the motor cannot be operated with this
starter).
Option 3: Starter used in IT system with ground fault monitoring:
3RW44, product version ≤ *E06* and the PROFIBUS DP communication module may not
be used in this network configuration.
Remedy: Replace starter with 3RW44, product version ≥ *E07*. This version can be used
in combination with the PROFIBUS DP communication module. However, the phase
voltage values (UL-N) and phase-to-phase voltage values (UL-L) may be displayed
incorrectly on the measurement-value display of the 3RW44.
Loss of phase L2 x Option 1: Phase L2 missing, drops or fails while motor is running.
A trip occurs due to a voltage drop in the permissible rated operating voltage of >15 %
>100 ms during starting, or >200 ms in bypass operation.
Remedy: Connect L2 or rectify voltage drop.
Option 2: The connected motor is too small and the error message is issued immediately
after switching to bridging mode.
Remedy: Adjust rated operating current for connected motor or set to minimum (if motor
current is lower than 10 % of the configured I
e, the motor cannot be operated with this
starter).
Option 3: Starter used in IT system with ground fault monitoring:
3RW44, product version ≤ *E06* and the PROFIBUS DP communication module may not
be used in this network configuration.
Remedy: Replace starter with 3RW44, product version ≥ *E07*. This version can be used
in combination with the PROFIBUS DP communication module. However, the phase
voltage values (UL-N) and phase-to-phase voltage values (UL-L) may be displayed
incorrectly on the measurement-value display of the 3RW44.
Loss of phase L3 x Option 1: Phase L3 missing, drops or fails while motor is running.
A trip occurs due to a voltage drop in the permissible rated operating voltage of >15 %
>100 ms during starting, or >200 ms in bypass operation.
Remedy: Connect L3 or rectify voltage drop.
Option 2: The motor that is connected is too small and the error message is issued
immediately after switching to bridging mode.
Remedy: Adjust rated operating current for connected motor or set to minimum (if motor
current is lower than 10 % of the configured I
e, the motor cannot be operated with this
starter).
Option 3: Starter used in IT system with ground fault monitoring:
3RW44, product version ≤ *E06* and the PROFIBUS DP communication module may not
be used in this network configuration.
Remedy: Replace starter with 3RW44, product version ≥ *E07*. This version can be
used in combination with the PROFIBUS DP communication module. However, the phase
voltage values (UL-N) and phase-to-phase voltage values (UL-L) may be displayed
incorrectly on the measurement-value display of the 3RW44.
Missing load phase T1 x Motor phase T1 is not connected.
Remedy: Connect motor correctly.
Missing load phase T2 x Motor phase T2 is not connected.
Remedy: Connect motor correctly.
Missing load phase T3 x Motor phase T3 is not connected.
Remedy: Connect motor correctly.
