A 31
EMF_KI
Parameter of EMF CONTROL-function block. ( S8/16 )
Integral action time of the EMF controller. Scaling:
TC = 147200 / EMF_KI;
1008 FB_P: I2 SC: - HL: 20000 LL: 0 D: 4905 U: ms
EMF_REG_LIM_P
Parameter of EMF CONTROL-function block. ( S8/16 )
Positive limit for EMF controller output.
1009 FB_P: I2 SC: FLUX HL: 4095 LL: 0 D: 410 U: %
EMF_REG_LIM_N
Parameter of EMF CONTROL-function block. ( S8/16 )
Negative limit for EMF controller output.
1010 FB_P: I2 SC: FLUX HL: 0 LL: -4095 D: -4095 U: %
EMF_REL_LEV
Parameter of EMF CONTROL-function block. ( S8/16 )
EMF controller blocking level. When measured EMF is below this level, the EMF-controller
is blocked.
1011 FB_P: I2 SC: EMF HL: 1000 LL: 0 D: 50 U: %
FIELD_WEAK_POINT
Parameter of EMF CONTROL-function block. ( S8/16 )
Speed of the motor where flux reference reduction is started.
1012 FB_P: I2 SC: SPEED HL: 23000 LL: 4000 D: 20000 U: rpm
FIELD_CONST_1
Parameter of EMF CONTROL-function block. ( S8/16 )
Field current reference which produces 40% flux in motor
(default: 29% of nominal field current).
1013 FB_P: I2 SC: CURR HL: 4095 LL: 0 D: 1187 U: %
FIELD_CONST_2
Parameter of EMF CONTROL-function block. ( S8/16 )
Field current reference which produces 70% flux in motor
(default: 53% of nominal field current).
1014 FB_P: I2 SC: CURR HL: 4095 LL: 0 D: 2190 U: %
FIELD_CONST_3
Parameter of EMF CONTROL-function block. ( S8/16 )
Field current reference which produces 90% flux in motor
(default: 79% of nominal field current).
1015 FB_P: I2 SC: CURR HL: 4095 LL: 0 D: 3255 U: %
GENER.EMF_REF
Parameter of EMF_CONTROL-function block (S8/16 | S21.232)
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.
