EMF_KI
Parameter of EMF CONTROL-function block.
Integral action time of the EMF controller. Scaling:
TC = 147200 / EMF_KI;
1008 FB_P: I2 SC: -
EMF_REG_LIM_P
Parameter of EMF CONTROL-function block.
Positive limit for EMF controller output.
1009 FB_P: I2 SC: FLUX
EMF_REG_LIM_N
Parameter of EMF CONTROL-function block.
Negative limit for EMF controller output.
1010 FB_P: I2 SC: FLUX
EMF_REL_LEV
Parameter of EMF CONTROL-function block.
EMF controller blocking level. When measured EMF is below this level, the EMF-controller
is blocked.
1011 FB_P: I2 SC: EMF
FIELD_WEAK_POINT
Parameter of EMF CONTROL-function block.
Speed of the motor where flux reference reduction is started.
1012 FB_P: I2 SC: SPEED
FIELD_CONST_1
Parameter of EMF CONTROL-function block.
Field current reference which produces 40% flux in motor
(default: 29% of nominal field current).
1013 FB_P: I2 SC: CURR
FIELD_CONST_2
Parameter of EMF CONTROL-function block.
Field current reference which produces 70% flux in motor
(default: 53% of nominal field current).
1014 FB_P: I2 SC: CURR
FIELD_CONST_3
Parameter of EMF CONTROL-function block.
Field current reference which produces 90% flux in motor
(default: 79% of nominal field current).
1015 FB_P: I2 SC: CURR
GENER.EMF_REF
Parameter of EMF_CONTROL-function block
This parameter has a similar function than LOCAL_EMF_REF. It sets the value of the local
EMF reference, if the drive is in regenerative mode. This function becomes active, if the
value is lower than the one of LOCAL_EMF_REF.
In case this value is lower than the one of LOCAL_EMF_REF, but GENER.WEAK_POINT
is still higher than FIELD_WEAK_POINT the converter will block the other bridge until the
motor voltage has dropped below the level set by GENER.WEAK_POINT. The drive is
coasting and the speed normally will go down.
