What to do
Check the source of the fault (parameter
32.27 Supervision 3 signal).
Check the external device.
Check setting of parameter
External event 1 source.
Check the external device.
Check setting of parameter
External event 2 source.
Check the external device.
Check setting of parameter
External event 3 source.
Check the external device.
Check setting of parameter
External event 4 source.
Check the external device.
Check setting of parameter
External event 5 source.
Check safety circuit connections. For
more information, see appropriate drive
hardware manual and description of
parameter 31.22 STO indication run/stop
(page 258).
Check the auxiliary code, The code
contains location information, especially
with parallel-connected inverter modules.
When converted into a 32-bit binary
number, the bits of the code indicate the
following:
31...28: Number of faulty inverter module
(0...11 decimal). 1111: STO_ACT states
of control unit and inverter modules in
conflict
27: STO_ACT state of inverter modules
26: STO_ACT state of control unit
25: STO1 of control unit
24: STO2 of control unit
23...12: STO1 of inverter modules 12...1
(Bits of non-existing modules set to 1)
11...0: STO2 of inverter modules 12...1
(Bits of non-existing modules set to 1)
