Group 15: Motor 2 Field - ABB DCS 500B Description

Group 15: MOTOR 2 FIELD

[F2_REF]
Input of MOTOR_2_FIELD-function block.
Field current reference for motor 2 field exciter.
1501 FB_I: C4
F2_CURR_GT_MIN_L
Parameter of MOTOR_2_FIELD-function block.
Tripping level of minimum field current monitoring function.
1502 FB_P: I2
F2_OVERCURR_L
Parameter of MOTOR_2_FIELD-function block.
Field overcurrent limit for motor 2. The default limit is 115% of nominal field current.
1503 FB_P: I2
F2_CURR_TC
Parameter of MOTOR_2_FIELD-function block
Filter time constant for actual field current measurement. (lower HL in S21.232)
1504 FB_P: I2
F2_KP
Parameter of MOTOR_2_FIELD-function block.
Proportional gain for PI controller in the field excitation unit .
1505 FB_P: I2
F2_KI
Parameter of MOTOR_2_FIELD-function block.
Integral action time for PI controller in the field excitation unit .
1506 FB_P: I2
F2_U_AC_DIFF_MAX
Parameter of MOTOR_2_FIELD_OPTIONS-function block
Threshold level for free-wheeling function. If two successive AC voltage measurements in
field exciter differ more than this then the 2 phase field exciter activates the free-wheeling
function. (lower HL in S21.232)
1507 FB_P: I2
F2_U_LIM_N
Parameter of MOTOR_2_FIELD-function block.
Negative output voltage limitation for current controller in field excitation unit.
Minimum output voltage = -4096.
1508 FB_P: I2 SC: VOLT
F2_U_LIM_P
Parameter of MOTOR_2_FIELD-function block.
Positive output voltage limitation for current controller in field excitation unit.
Maximum output voltage = 4096.
1509 FB_P: I2 SC: VOLT
F2_RED.SEL
Parameter of MOTOR_2_FIELD -function block.
Enables field heating function for the motor when the RUN-command is not active.
The function is activated 10 s after the RUN-command has been removed.
0 = DISABLE
1 = ENABLE
