DETAILED PARAMETER DESCRIPTION
P0414 - Magnetizing voltage
Adjustable range: 0.0 to 20.0 % Factory setting: 0.0 %
Acesso: Menu → Configurations → Nominal data → Motor
Description:
It is a percentage of the nominal voltage applied for (2 x P0412) seconds to ensure the magnetization of the
motor before the start.
✓
NOTE!
This parameter is only visible on the HMI when: the control type is scalar, P0202 = 0, 1 or 2 (V/F
control).
P0427 - Inductance LD sigma
Adjustable range: 0.00 to 99.99 mH Factory setting: 4.85 mH
Acesso: Menu → Configurations → Nominal data → Motor
Description:
Motor parameter used on the stator flux observer.

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).
