Safe torque off
Programmable fault:
Safe torque off function is
active, i.e. safety circuit
signal(s) connected to
connector XSTO is broken
during start or run.
Check safe torque off circuit connections.
For more information, see appropriate
drive hardware manual and description of
parameter
(page
).
5092
PU logic error
Power unit memory has
cleared.
Cycle the power to the drive. If the
control unit is externally powered, also
reboot the control unit (using parameter
) or by cycling
its power. If the problem persists, contact
your local ABB representative.
5093
Rating ID mismatch
The hardware of the drive does
not match the information
stored in the memory unit. This
may occur eg. after a firmware
update or memory unit
replacement.
Cycle the power to the drive.
Check the auxiliary code. The auxiliary
code categories are as follows:
1 = PU and CU ratings not the same.
Rating ID has changed.
2 = Parallel connection rating ID has
changed.
3 = PU types not the same in all power
units.
4 = Parallel connection rating ID is active
in a single power unit setup.
5 = It is not possible to implement the
selected rating with the current PUs.
6 = PU rating ID is 0.
7 = Reading PU rating ID or PU type
failed on PU connection.
8 = PU not supported (illegal rating ID).
9 = Incompatible module current rating
(unit contains a module with too low a
current rating).
10 = Selected parallel rating ID not found
from database.
With parallel connection faults (BCU
control unit), the format of the auxiliary
code is 0X0Y. “Y” indicates the auxiliary
code category, “X” indicates the first
faulty PU channel in hexadecimal (1…C).
(With a ZCU control unit, “X” can be 1 or
2 but this is irrelevant to the fault.)
