Read the PSL2 data log. In Drive
Composer pro, check the time stamp of
the A580 fault. Load the log with the
same date and time. When the file
opens, click “Show fault log”.
Check the power unit hardware.
Check the setting of parameter 95.20
HW options word 1, bit 14.
Cooling fan feedback missing.FanA581
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.

Check that the auxiliary fan supervision
selection in parameter 95.21 HW options
word 2 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 drive
Safe torque off function is active, i.e.
safety circuit signal(s) connected to
connector XSTO is lost.
