30 FAULT FUNCTIONS
Programmable protection functions
3001 AI<MIN FUNCTION Defines the drive response if the analog input (AI) signal drops below the
fault limits and AI is used
• as the active reference source (group
11 REFERENCE SELECT )
• as the process or external PID controllers' feedback or setpoint source
(group
40 PROCESS PID SET 1 ) and the corresponding PID controller is
active.
3021 AI1 FAULT LIMIT sets the fault limits
0 = NOT SEL
0 = NOT SEL Protection is inactive.
1 = FAULT The drive trips on fault AI1 LOSS (code: F0007 ) and the motor coasts to stop.
Fault limit is defined by parameter 3021 AI1 FAULT LIMIT.
2 = CONST SP 7
The drive generates alarm AI1 LOSS (code: A2006 ) and sets the speed to
the value defined by parameter 1208 CONST SPEED 7. The alarm limit is
defined by parameter 3021 AI1 FAULT LIMIT.
WARNING! Make sure that it is safe to continue operation in case
the analog input signal is lost.
3 = LAST SPEED The drive generates alarm AI1 LOSS (code: A2006 ) and freezes the speed to
the level the drive was operating at. The speed is determined by the average
speed over the previous 10 seconds. The alarm limit is defined by parameter
3021 AI1 FAULT LIMIT.
WARNING! Make sure that it is safe to continue operation in case
the analog input signal is lost.
3003 EXTERNAL FAULT 1 Selects an interface for an external fault 1 signal. 0 = NOT SEL
0 = NOT SEL Not selected
1 = DI1 External fault indication through digital input DI1. 1: Fault trip on EXT FAULT
1 (code: F0014 ). Motor coasts to stop. 0: No external fault.
2 = DI2 See selection DI1.
3 = DI3 See selection DI1.
4 = DI4 See selection DI1.
5 = DI5 See selection DI1.
-1 = DI1(INV) External fault indication through inverted digital input DI1. 0: Fault trip on EXT
FAULT 1 (code: F0014 ). Motor coasts to stop. 1: No external fault.
-2 = DI2(INV) See selection DI1(INV).
-3 = DI3(INV) See selection DI1(INV).
-4 = DI4(INV) See selection DI1(INV).
-5 = DI5(INV) See selection DI1(INV).
3004 EXTERNAL FAULT 2 Selects an interface for an external fault 2 signal. 0 = NOT SEL
See parameter 3003 EXTERNAL FAULT 1.
