256 Actual signals and parameters
3022 AI2 FAULT
LIMIT
Defines a fault level for analog input AI2. If parameter 3001
AI<MIN FUNCTION is set to FA U LT, the drive trips on fault
AI2 LOSS (0008) when the analog input signal falls below
the set level.
Do not set this limit below the level defined by parameter
1304 MINIMUM AI2.
0.0%
0.0…100.0% Value as a percentage of the full signal range 1 = 0.1%
3023 WIRING FAULT Selects how the drive reacts when incorrect input power and
motor cable connection is detected (ie, the input power
cable is connected to the motor connection of the drive).
Note: Disabling wiring fault (ground fault) may void the
warranty.
ENABLE
DISABLE No action 0
ENABLE The drive trips on fault OUTP WIRING (0035). 1
3025 STO
OPERATION
Selects how the drive reacts when the drive detects that the
STO (Safe torque off) function is active.
ONLY
ALARM
ONLY FAULT The drive trips on fault SAFE TORQUE OFF (0044). 1
ALARM&FAUL
T
The drive generates alarm SAFE TORQUE OFF (2035)
when stopped and trips on fault SAFE TORQUE OFF
(0044) when running.
2
NO & FAULT The drive gives no indication to the user when stopped and
trips on fault SAFE TORQUE OFF (0044) when running.
3
ONLY ALARM The drive generates alarm SAFE TORQUE OFF (2035).
Note: The start signal must be reset (toggled to 0) if STO
(Safe torque off) has been used while the drive has been
running.

3026 POWER FAIL
START
Selects how the drive reacts when the control board is
externally powered by the MPOW-01 auxiliary power
extension module (see Appendix: Extension modules on
page 411) and start is requested by the user.
ALARM
ALARM The drive generates alarm UNDERVOLTAGE (2003). 1
FAULT The drive trips on fault DC UNDERVOLT (0006). 2
NO The drive gives no indication to the user. 3
3027 OPTION COM
LOSS
Selects how the drive reacts when the MREL-01 output
relay module is removed from the drive, and parameters
1402 RELAY OUTPUT 2, 1403 RELAY OUTPUT 3 or 1410
RELAY OUTPUT 4 have non-zero values.
