Enable flux weak
Command for
Voltage control
.
ON
The field current corresponds to the value set via the
Flux cur-
rent min
parameter.
OFF
The field current is regulated on the basis of the functioning
mode and on the drive working setpoint.
Speed-0 f weak
When this function is enabled, and the speed 0 threshold is reached, it will be produced
the minimum field current set via
Flux current min
.
Supposing that:
Start
= Low level and/or
Fast stop
= Low level
Set as field economy:
To avoid the overheating of motors which should not run or to avoid the presence of conden
-
sation in motor which work externally ( the field will be used as anti condensation heating).
ON
Enabled function
OFF
Disabled function
Flux reference
Flux/current reference : the 100% corresponds to the
Motor nom flux
parameter.
With the function Flux / if curve defined, this reference corresponds to the flux reference.
With the function Flux / if curve not defined (default conditions), this reference cor
-
responds to the field current reference.
Flux curr (%)
Field current feedback, expressed as percentage of the
Motor nom flux
parameter.
Out vlt level
Percentage of the maximum output voltage according to the
Max out voltage
parameter.
This parameter allows the changing of the output voltage in “Voltage control”
(FLUX REGULATION\Flux reg mode).
FC cur ref hyst
Parameter of the “Three-phase external exciter control” function, see "A2.5 External
Three-phase Field Exciter Control" on page 493.
This parameter can be used to avoid continuous reversal of field current polarity when
the motor is running with no load or a limited load applied and thus with a Speed reg
output value that is almost null.
I field cnst 40
Current value at 40% of flux (see Flux /if curve, paragraph 5.3.7)
I field cnst 70
Current value at 70% of flux (see Flux /if curve, paragraph 5.3.7)
I field cnst 90
Current value at 90% of flux (see Flux /if curve, paragraph 5.3.7)
Set flux / if
Command for the setting of the flux curve according to the setting of
I field cnst 40-70-
90
parameter. With the defined curve, the meaning of
Flux current max/Flux refer-
ence
indicates only the flux percentage according to the characteristic of this curve. As
