When set to 1 the field controller becomes a voltage controller which controls the voltage applied to the field winding.
When set to 0 field controller operates as a current controller.
This parameter indicates the average rms voltage across the E1 E3 input terminals. Filtered by a 100 ms first order filter.
When this parameter is set to 0 the internal and external field controllers are disabled. Setting the parameter to 1 enables the internal or external field
controller. If using a Permanent Magnet motor or external field regulators, it is necessary to mask the FdL trip. Refer to Pr 10.52 to Pr 10.61 (Trip
masks).
When the parameter is set to internal (IntrnL) the internal field controller is used. Pr 5.54, Pr 5.56 {di09, 0.44}, Pr 5.57, Pr 5.58 and Pr 5.60 are con-
trolled by the internal field controller.
When the parameter is set to external half control (EtrnL) or external in full control (E FULL) the drive will use the external field controller. Pr 5.54,
Pr 5.56 {di09, 0.44}, Pr 5.57, Pr 5.58 and Pr 5.60 will now be controlled by the external field controller. If no signal is received from the external field
controller the drive will trip field loss.
When this bit is set the economy timeout feature is selected.
When set to 1 the field economy level is selected. When set to 0 field economy is controlled by the field economy timeout function.
