2608 SLIP COMP RATIO Defines the slip gain for the motor slip compensation control. 100% means
full slip compensation, 0% means no slip compensation. Other values can be
used if a static speed error is detected despite of the full slip compensation.
Example: 35 Hz constant speed reference is given to the drive. Despite of the
full slip compensation (SLIP COMP RATIO = 100%), a manual tachometer
measurement from the motor axis gives a speed value of 34 Hz. The static
speed error is 35 Hz - 34 Hz = 1 Hz. To compensate the error, the slip gain
should be increased.

30 FAULT FUNCTIONS
Programmable protection functions
3001 AI<MIN FUNCTION Selects how the drive reacts when an analog input signal falls below the set
minimum limit.
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 (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 (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.
