Group 10: Emf Control - ABB DCS 500B Description

Group 10: EMF CONTROL

FIELD_MODE
Parameter of EMF CONTROL-function block.
Selects the operating mode of motor field control:
0 = CONSTANT FIELD
1 = EMF, NO FIELD REV
2 = NO EMF, FIELD REV
3 = EMF+FIELD REV
4 = NO EMF, OPTITORQUE
5 = EMF+OPTITORQUE
1001 FB_P: E2
[FLUX_REF]
Input of EMF CONTROL-function block.
This is an input for flux reference. EMF CONTROL-block is using either flux or EMF
reference.
1002 FB_I: C4
[EMF_REF]
Input of EMF CONTROL-function block.
This is an input for EMF reference. EMF CONTROL-block is using either flux or EMF
reference.
1003 FB_I: C4
[FLUX_REF_SEL]
Input of EMF CONTROL-function block.
This is an input for flux reference selection. It will select either [FLUX_REF] input or
constant reference of 100%.
0 = internal reference
<>0 = [FLUX_REF] input.
1004 FB_I: C4
[EMF_REF_SEL]
Input of EMF CONTROL-function block.
This is an input for EMF reference selection. It will select either [EMF_REF] input or
LOCAL_EMF_REF-parameter.
0 = LOCAL_EMF_REF-parameter
<>0 = [EMF_REF] input.
1005 FB_I: C4
LOCAL_EMF_REF
Parameter of EMF CONTROL-function block.
Sets the value of local EMF reference.
1006 FB_P: I2
EMF_KP
Parameter of EMF CONTROL-function block.
Proportional gain of the EMF controller. Gain is reduced above field weakening point with
a factor 1/n to keep the process gain constant. Scaling:
150 = gain is 54 %
277 = gain is 100 %.
1007 FB_P: I2
No EMF-control (constant field) without field
reversal.
EMF-control without field reversal.
No EMF-control (constant field) with field
reversal.
EMF-control with field reversal.
OPTITORQUE without EMF-control.
OPTITORQUE with EMF-control.
