Group 13: Motor 1 Field - ABB DCS 500B Description

Group 13: MOTOR 1 FIELD

[F1_REF]
Input of MOTOR_1_FIELD-function block.
Field current reference for motor 1 field exciter.
1301 FB_I: C4 SC: FCURR
[F1_FORCE_FWD]
Input of MOTOR_1_FIELD-function block.
Command to force motor field in forward direction.
1302 FB_I: C4 SC: BI
[F1_FORCE_REV]
Input of MOTOR_1_FIELD-function block.
Command to force motor field in reverse direction.
1303 FB_I: C4 SC: BI
[F1_ACK]
Input of MOTOR_1_FIELD-function block.
Input for analog or digital acknowledge signal from external field excitation system.
1304 FB_I: C4 SC: -
F1_CURR_GT_MIN_L
Parameter of MOTOR_1_FIELD-function block.
Tripping level of minimum field current monitoring function.
When field weakening function is used, this limit must be low enough to prevent minimum
field faults at high speed!
1305 FB_P: I2 SC: FCURR
F1_OVERCURR_L
Parameter of MOTOR_1_FIELD-function block.
Field overcurrent limit for motor 1. The default limit is 115% of nominal field current.
1306 FB_P: I2 SC: FCURR
F1_CURR_TC
Parameter of MOTOR_1_FIELD-function block
Filter time constant for actual field current measurement. (lower HL in S21.232)
1307 FB_P: I2
F1_KP
Parameter of MOTOR_1_FIELD-function block.
Proportional gain for PI controller in the field excitation unit .
1308 FB_P: I2 SC: -
F1_KI
Parameter of MOTOR_1_FIELD-function block.
Integral action time for PI controller in the field excitation unit .
1309 FB_P: I2 SC: 0.01
F1_U_AC_DIFF_MAX
Parameter of MOTOR_1_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)
