DETAILED PARAMETER DESCRIPTION
The CT primary current must be smaller than 1.95 times the transformer primary rated current.
WARNING!
In case the user sets a value in P1550 that is out of the mandatory range, programming error will
occur.
✓
NOTE!
This parameter can be changed only with the motor stopped.
This parameter is only visible on the HMI when: P1893 (Transformer at the input) = 2 or 3 trans-
formers.
P1557 - Taps of transformer 2
Adjustable range: -5.00 to 5.00 % Factory setting: 0.00 %
Acesso: Menu → Configurations → Nominal data → Inverter
Description:
It sets the modification occurred on the voltage supplied for the inverter cells.
Set it according to the input transformer tap connections.
✓
NOTE!
This parameter can be changed only with the motor stopped.
This parameter is only visible on the HMI when: P1893 (Transformer at the input) = 2 or 3 trans-
formers.
P1558 - Transformer 2 rated power
Adjustable range: 0 to 10000 kVA Factory setting: 1500 kVA
Acesso: Menu → Configurations → Nominal data → Inverter
Description:
It sets the rated power of the input transformer, in kVA.
Set it according to the nameplate data of the transformer used.
✓
NOTE!
This parameter can be changed only with the motor stopped.
This parameter is only visible on the HMI when: P1893 (Transformer at the input) = 2 or 3 trans-
formers.
P1559 - Transformer 3 CT Ratio
Adjustable range: 50 to 3000 Factory setting: 200
Acesso: Menu → Configurations → Nominal data → Inverter
Description:
It sets the ratio of the current transformers used in the measurement of the inverter input current.
