I/O
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Once the inverter is with the fault state active, and the fault origin condition is no longer active.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 8.1 COMMON
FUNCTIONS on page 8-1 for more information.
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) (Figure 9.15 on page 9-19).

s) SAFETY SWITCH
Only one inactive pulse in the DIx disables the inverter (Figure 9.17 on page 9-20).
