DETAILED PARAMETER DESCRIPTION
Minimum field for frequency lower than or equal to P0452.
Used in the soft-start function without rotor orientation in scalar mode.
✓
NOTE!
Function used in motor without encoder.
✓
NOTE!
This parameter is only visible on HMI when: P0950 = 1 (Synchronous motor with brushes) or
P0950 = 2 (Brushless synchronous motor).
This parameter is only visible on the HMI when: the control type is scalar, P0202 = 0, 1 or 2 (V/F
control).
P0452 - Field input frequency
Adjustable range: 0.0 to 60.0 Hz Factory setting: 0.0 Hz

Description:
Input frequency of the field excitation in scalar mode used in the soft-start function without rotor orientation.
✓
NOTE!
In scalar mode without encoder, the motor must “match” the inverter, and it is not possible to
start motors with currents higher than the inverter current.
When encoder is used, this parameter must be set to 0 Hz, disabling the soft-start without
encoder function.
For further information, contact WEG Technical Assistance.
WARNING!
For encoder setting:
Set parameter P0452 (Field input frequency) to 0 Hz.
Control Type (P0202) must be scalar and the direction of rotation forward; configure one of the
analog outputs for the encoder setting (E.g.: P0656 = [018] (EncAdjMS).

NOTE!
This parameter is only visible on HMI when: P0950 = 1 (Synchronous motor with brushes) or
P0950 = 2 (Brushless synchronous motor).
This parameter is only visible on the HMI when: the control type is scalar, P0202 = 0, 1 or 2 (V/F
control).
P0453 - Field ramp time
Adjustable range: 0.00 to 30.00 s Factory setting: 1.00 s
