Fault tracing 377
FA81
Drive interlock 1 loss
Drive interlock function is
active, ie. DIL circuit 1 is
broken.
Check safety circuit connections. For
more information, see appropriate drive
hardware manual and description of
parameter
(page
).
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: DIL_ACT states of
control unit and inverter modules in
conflict
27: DIL_ACT state of inverter modules
26: DIL_ACT state of control unit
25: DIL1 of control unit
24: DIL2 of control unit
23…12: DIL1 of inverter modules 12…1
(Bits of non-existing modules set to 1)
11…0: DIL2 of inverter modules 12…1
(Bits of non-existing modules set to 1)
FA82
Drive interlock 2 loss
Drive interlock function is
active, ie. DIL circuit 2 is
broken.
FA90
DIL diagnostics failure
SW internal malfunction.
Reboot the control unit (using parameter
) or by cycling
power.
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 memory unit is empty, or
contains incompatible or
corrupted firmware.
Recycle the power to the control unit.
Check the sticker on the memory unit to
confirm that the firmware is compatible
with the control unit (ZCU-1x/BCU-x2).
Connect Drive composer PC tool
(version 2.3 or later) to the drive. Select
Tools - Recover drive.
If the problem persists, replace the
memory unit.
