3.2.20 Command: FA - Fault
Function:
as only main faults have front panel LED indications, when the
generic LED DRVF lights up, it is necessary to interrogate
the drive via FA command. The answer is a codified ASCII string
(see below). Another function of the command is to reset the faults
occurred at logic level (also resettable via push button).
Syntax:
status monitoring and reset:
n
address FA <CR>
Address type:
axis
Password:
no
(
∗
) addressing:
no
Answer explanation: A a FA b c d e f g P h i j k l MA m n o B p q r
A
= axis
a
= axis address
FA
= fault
b
= Resolver connection
0 = OK
1 = not OK
c
= Motor temperature
0 = OK
1 = overtemperature
d
= Axis short circuit
0 = OK
1 = short circuit
e
= 3-phase sequence
0 = OK
1 = not coherent phase
f
= Velocity error
0 = OK
1 = not OK
g
= It
0 = off
1 = on
P
= Power supply
h
= Recovery unit
0 = OK
1 = not OK
i
= PWRS temperature
0 = OK
1 = overtemperature
j
= 220Vac 3-phase sequence
0 = OK
1 = unbalanced phase
k
= nc
l
= Personality card
0 = OK
1 = not OK*
MA
= A module (DBM module)
m
= BUS BAR voltage
0 = OK
1 = overvoltage/undervoltage
n
= Aux. Volt. ref. to - HV
0 = OK
1 = out of tolerance
o
= A module temperature
0 = OK
1 = overtemperature
B
= B module (eventual expansion module)
p
= BUS BAR voltage
0 = OK
1 = overvoltage/undervoltage
q
= Aux. Volt. ref. to - HV
0 = OK
1 = out of tolerance
r
= B module temperature
0 = OK
1 = overtemperature
* = in case of checksum error, check the parameters (e.g. KP, KI,...), correct the wrong values and save.
Note: If the expansion missing, the last characters are not significant.
Examples:
n
1 FA <CR>:
if OK, the answer will be: "A1 FA 000000 P 00000 MA 000 B 000"
