F
This parameter may be programmed even when no dynamic regulation of the
field current in field weakening mode is needed. It represents the value,
expressed as a percentage of C010 (IfldNom), to which the field current is
increased according to the time set at parameter C018 (FldFrcTime), starting
from the very moment when the run command is operated. This is true only
when a digital input configured for the 11:FldFrcEnabled function is closed.
This forcing function (Field Forcing) will be disabled if the armature voltage exceeds the following value
2
316.1030C
, and will be enabled when drive is started again. See also the FIELD REGULATOR chapter.
NOTE
Product C010•C017 should not exceed the 100% of the field maximum current
to be supplied by the device.
NOTE
The forcing function may have no effect if the current increase does not produce
any remarkable field flux increase.

F
This parameter may be programmed even when no dynamic regulation of the
field current in field weakening mode is needed. This is the time interval,
expressed in seconds, during which the field current is increased according to
the percentage set at parameter C017 (FldFrcLevel) starting from the very
moment when the run command is operated. See also the FIELD REGULATOR
chapter.

F
This parameter sets, in Volts, the three-phase mains voltage nominal value in
the power section.
The upper extreme value to be set (i.e. the maximum three-phase voltage to be
supplied to the power section) indicated as NNN, is factory-set, is shown in the
Status page and depends on the components used for the device
manufacturing. It may be one of the following four values: 440V, 500V, 600V,
690V.
The value set in this parameter controls alarm A016 (Mains OverVoltage), A017
(Mains UnderVoltage) and A010 (Armature OverVoltage) trip (mains overvoltage
or undervoltage and armature overvoltage respectively).
NOTE
The value set in this parameter cannot exceed the drive factory-set value.
