Check the auxiliary code to identify
the fan. Code 0 denotes main fan 1.
Other codes (format XYZ): “X”
specifies state code (1: ID run, 2:
normal). “Y” specifies the index of the
inverter module connected to BCU
(0…n, always 0 for ZCU control units).
“Z” specifies the index of the fan (1:
Main fan 1, 2: Main fan 2, 3: Main fan
3).
Note that modules are coded starting
from 0. For example, the code 101
means that Main fan 1 of module 1
(connected to BCU channel V1T/V1R)
has faulted during its ID run.
Check fan operation and connection.
Replace fan if faulty.
The auxiliary code identifies the fan
(1: Auxiliary fan 1, 2: Auxiliary fan 2).
An auxiliary cooling fan (connected to
the fan connectors on the control unit)
is stuck or disconnected.
Auxiliary fan
not running
A582
Check that the auxiliary fan
supervision selection in parameter
matches the
hardware.
Make sure the front cover of the drive
module is in place and tightened.
Check auxiliary fan(s) and
connection(s).
Replace faulty fan.
Check safety circuit connections. For
more information, see appropriate
Safe torque off function is active, i.e.
safety circuit signal(s) connected to
connector XSTO is lost.
