FEXC_SEL
Parameter of SETTINGS-function block.
Selection for the type of the field exciter or the type of acknowledgement signal from old
field exciters:
0 = NO FIELD EXCITER
1 = DIODE FIELD EXC.
2 = FEX2 OR FEX3
3 = FEX3 FOR MOTOR2
4 = FEX2/3 + MOT2=FEX3
5 = FIELD ACK VIA DI
6 = FIELD ACK VIA AI
505 FB_P: E2 SC: -
PHASE_SEQ_CW
Parameter of SETTINGS-function block.
The phase order of converter supply voltage. If measured phase order does not match
with this parameter, fault 38 "Phase sequence fault" is generated.
1 = R-T-S
2 = R-S-T
506 FB_P: E2 SC: -
U_SUPPLY
Parameter of SETTINGS-function block
Nominal value of converter supply voltage. (higher HL in S21.232)
507 FB_P: I2 SC: 1
U_NET_MIN1
Parameter of CONVERTER_PROTECTION-function block.
Upper limit for supply undervoltage monitoring in %. If supply voltage falls below this limit,
controllers are blocked. Undervoltage trip is generated if network voltage does not return
to a higher value than U_NET_MIN1 during time defined by PWR_DOWN_TIME.
508 FB_P: I2 SC: 1
U_NET_MIN2
Parameter of CONVERTER_PROTECTION-function block.
Lower limit for supply undervoltage monitoring in %. If supply voltage falls below this limit,
the drive will trip immediately.
509 FB_P: I2 SC: 1
PWR_DOWN_TIME
Parameter of CONVERTER_PROTECTION-function block.
During this time the supply voltage must return to a value higher than U_NET_MIN1.
Otherwise an undervoltage trip will be generated.
510 FB_P: I2 SC: 1
ARM_OVERVOLT_LEV
Parameter of CONVERTER_PROTECTION-function block.
Armature overvoltage tripping level in % of nominal voltage of motor.
511 FB_P: I2 SC: 1
ARM_OVERCURR_LEV
Parameter of CONVERTER_PROTECTION-function block.
Armature overcurrent tripping level in % of converter nominal current.
512 FB_P: I2 SC: 1
