Fault tracing 603
FA81 Safe torque off 1 loss Safe torque off function is
active, ie. STO circuit 1 is
broken.
Check safety circuit connections. For
more information, see appropriate drive
hardware manual and description of
parameter 31.22 STO indication run/stop
(page 306).
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)
FA82 Safe torque off 2 loss Safe torque off function is
active, ie. STO circuit 2 is
broken.
FB11 Memory unit missing No memory unit is attached to
the control unit.
Power down the control unit.
Check that the memory unit is properly
inserted into the control unit.
The memory unit attached to
the control unit is empty.
Power down the control unit. Attach a
memory unit (with the appropriate
firmware) to the control unit.
FB12 Memory unit
incompatible
The memory unit attached to
the control unit is incompatible.
Power down the control unit.
Attach a compatible memory unit.
FB13 Memory unit FW
incompatible
The firmware on the attached
memory unit is incompatible
with the drive.
Power down the control unit.
Attach a memory unit with compatible
firmware.
FB14 Memory unit FW load
failed
The firmware on the attached
memory unit could not be
loaded to the drive.
Power down the control unit.
Check that the memory unit is properly
inserted into the control unit.
If the problem persists, replace the
memory unit.
FF61 ID run Motor ID run was not
completed successfully.
Check the nominal motor values in
parameter group 99 Motor data.
Check that no external control system is
connected to the drive.
Cycle the power to the drive (and its
control unit, if powered separately).
Check that the motor shaft is not locked.
Check the auxiliary code. The second
number of the code indicates the
problem (see actions for each code
below).
