ABB DriveIT ACH550-UH - Group 30: Fault Functions

96 ACH550-UH User’s Manual
Start-Up
Group 30: Fault Functions
This group defines situations that the drive should recognize as potential faults and defines how the
drive should respond if the fault is detected.
Group 30: Fault Functions
Code Description Range Resolution Default S
3001 AI<MIN FUNCTION 0…3 1 0
Defines the drive response if the analog input (
AI) signal drops below the fault limits and AI is used in reference
chain.
• 3021 AI1 FAULT LIMIT and 3022 AI2 FAULT LIMIT set the minimum limits
0 =
NOT SEL – No response.
1 =
FAULT – Displays a fault (7, AI1 LOSS or 8, AI2 LOSS) and the drive coasts to stop.
2 =
CONST SP 7 – Displays a warning (2006, AI1 LOSS or 2007, AI2 LOSS) and sets speed using 1208 CONST SPEED 7.
3 =
LAST SPEED – Displays a warning (2006, AI1 LOSS or 2007, AI2 LOSS) and sets speed using the last operating
level. This value is the average speed over the last 10 seconds.
Warning! If you select CONST SP 7 or LAST SPEED, make sure that continued operation is safe when the analog
input signal is lost.
3002 PANEL COMM ERR 1…3 1 1
Defines the drive response to a control panel communication error.
1 =
FAULT – Displays a fault (10, PANEL LOSS) and the drive coasts to stop.
2 =
CONST SP 7 – Displays a warning (2008, PANEL LOSS) and sets speed using 1208 CONST SPEED 7.
3 =
LAST SPEED – Displays a warning (2008, PANEL LOSS) and sets speed using the last operating level. This value is
the average speed over the last 10 seconds.
Warning! If you select CONST SP 7 or LAST SPEED, make sure that continued operation is safe when the control
panel communication is lost.
3003 EXTERNAL FAULT 1 -6…6 1 0
Defines the External Fault 1 signal input and the drive response to an external fault.
0 =
NOT SEL – External fault signal is not used.
1 =
DI1 – Defines digital input DI1 as the external fault input.
• Activating the digital input indicates a fault. The drive displays a fault (14,
EXTERNAL FAULT 1) and the drive coasts
to stop.
2…6 =
DI2…DI6 – Defines digital input DI2…DI6 as the external fault input.
• See
DI1 above.
-1 =
DI1(INV) – Defines an inverted digital input DI1 as the external fault input.
• De-activating the digital input indicates a fault. The drive displays a fault (14,
EXTERNAL FAULT 1) and the drive
coasts to stop.
-2…-6 = DI2(INV)…DI6(INV) – Defines an inverted digital input DI2…DI6 as the external fault input.
• See
DI1(INV) above.
3004 EXTERNAL FAULT 2 -6…6 1 0
Defines the External Fault 2 signal input and the drive response to an external fault.
• See parameter 3003 above.
3005 MOT THERM PROT 0, 2 1 1
Defines the drive response to motor overheating.
0 =
NOT SEL – No response and/or motor thermal protection not set up.
1 =
FAULT – When the calculated motor temperature exceeds 90 C, displays a warning (2010, MOT OVERTEMP).
When the calculated motor temperature exceeds 110 C displays a fault (9,
MOT OVERTEMP) and the drive coasts to
stop.
2 = WARNING – When the calculated motor temperature exceeds 90 C, displays a warning (2010, MOT OVERTEMP).
