DETAILED PARAMETER DESCRIPTION
P0446 - Base field current
Adjustable range: 0.1 to 999.9 A Factory setting: 33.3 A
Acesso: Menu → Configurations → Control
Description:
Current base used for the field current.
✓
NOTE!
This parameter is only visible on the HMI when: P0950 = 1 (Synchronous motor with brushes).
This parameter is only visible on the HMI when: the control type is vector, P0202 = 3 (Sensorless
Vector) or P0202 = 4 (Vector with Encoder).
P0449 - Maximum field current (Brushless)
Adjustable range: 0.01 to 5.00 PU Factory setting: 0.70 PU
Acesso: Menu → Configurations → Protections
Description:
Maximum limit in PU of P0462 used in the control of the field current reference; see Section 5.2 FIELD EXCI-
TATION SET (DC WITH BRUSHES) on page 5-3 of the User’s Manual.
Set according to the possible overload on the inverter/exciter.
✓
NOTE!
This parameter is only visible on HMI when: P0950 = 1 (Synchronous motor with brushes) or
P0950 = 2 (Brushless synchronous motor).
P0450 - Minimum field current (Brushless)
Adjustable range: 0.01 to 5.00 PU Factory setting: 0.01 PU
