Digital and Analog Inputs and Outputs
g) 2 RAMP
nd
If DIx is inactive, the inverter uses the default ramp by P0100 and P0101; otherwise, it will use the 2
P0102 and P0103.
h) NO EXTERNAL ALARM
If DIx is inactive, the inverter will activate the external alarm A0090.
i) NO EXTERNAL FAULT
If DIx is inactive, the inverter will activate the external fault F0091. In this case, the PWM pulses are disabled
immediately.
j) FAULT RESET
Once the inverter is in the fault status and the fault origin condition is no longer active, the fault status will be reset
in the transition of the DIx programmed for this function.
k) USE OF SoftPLC
Only the digital input status Dix in P0012 is used for the SoftPLC functions.

l) Automatic / Manual for Main PID configures the input to select the operating mode of the Main PID Controller,
being automatic with the application of 0 V, or manual with the application of 24 V. Parameter P1018 defines
its functionality in the operation of the Main PID Controller.
m) Automatic / Manual for External PID configures the input to select the operating mode of the External
PID Controller, being automatic with the application of 0 V, or manual with the application of 24 V. Parameter
P1065 defines its functionality in the operation of the External PID Controller.
NOTE!
In options 20 and 21, in case two or more analog inputs are selected for the same function, for instance,
P0266 = 20 and P0267 = 20, only the analog input with higher priority will be valid, being DI1 > DI2
> DI3 > DI4, that is, in this case the digital input DI4 will be the input used as automatic/manual of
the main PID controller. Refer to
