Parameter Description Action
NOTE
: verify on the inverter of ECI fan of
chopped phase driver that with this input a
proper output is supplied to the fan.
AOt = 5 Time of analog output at max
after the start With AOt = 5 the controller supplies 10V output
for 5s at fan start, then starts standard
regulation
MPM = 100 Maximum % variation per
minute The analog output takes 1 min to move from
the min to the maximum
21.2.2 How to set it
Parameters involved: AoC = tEn, AoF = FrE, AOP = P3: LAO = 20; UAO = 40; Aot = 0, AOM = 30,
MPM = 100

a. Set the kind of signal of the analog output current (4-20ma) or voltage (0-10V) by the Analog
output setting
parameter “ AoC”: tEn =
0÷10V output; cUr = 4-20mA output
b. Set the function of the analog output:
AoF = FrE
c.
Set the time of the analog output at max after start up EI: Aot = 3s
d.
Set the start scale temperature by LAO parameter, at which correspond the AOM value of
analog output
e.
Set the end scale temperature by UAO parameter, at which correspond the maximum value
of analog output
f.
Set the max % variation per min (MPM)
g. At last set also the percentage of analog output in case of probe failure : (0 ÷ 100%) SAO
