nd
RAMP
If DIx is inactive, the inverter uses the default ramp by P100 and P101, otherwise, it will use the 2
nd
Ramp by P102
and P103.

l) NO EXTERNAL ALARM
If DIx is inactive, the inverter will activate the external alarm A090.
m) NO EXTERNAL FAULT
If DIx is inactive, the inverter will activate the external fault F091. In this case, the PWM pulses are disabled
immediately.
n) FAULT RESET
Once the inverter is with the fault state active, and the fault origin condition is no longer active.
The reset of the fault state will occur when the DIx set for this function is active.
o) DISABLE FLYING START
It allows the DIx, when active, to disable the action of the Flying Start function preset in parameter P320 = 1 or 2.
When the DIx is inactive, the Flying Start function operates normally again. Refer to
Section 11.3 FLYING START
/ RIDE-THROUGH on page 11-7 .
p) LOCK PROG
When the DIx input is active, parameters cannot be changed, no matter the values set in P000 and P200. When
the DIx input is Inactive, the modification of parameters will depend on the values set in P000 and P200.
q) ACCELERATE E.P. - TURN ON / DECELERATE E.P. - TURN OFF
It consists of the Electronic Potentiometer function with capacity to enable the inverter by means of a pulse at the
start, and a pulse for the stop when the output speed is minimum (P133).
