DescriptionName / Range /
Selection
No.
Warning / uint16Selects how the drive reacts when a main cooling fan
fault is detected.
Note: With an inverter unit consisting of one or more
frame R8i inverter modules with speed-controlled fans,
it may be possible to continue operation even if one
main fan of a module stops. When fan failure is
detected, the control program will automatically
• set the other fan of the module to full speed
• set the fans of the other modules (if any) to full
speed
• decrease the switching frequency to a minimum,
and
• disable the supervision of temperature difference
between the modules.
If this parameter is set to Fault, the inverter unit will
trip (but still carry out the actions listed above).
Otherwise, the inverter will attempt to continue
operation.
Main fan fault
function
31.35
0The drive trips on fault 5080 Fan.Fault
1The drive generates an A581 Fan.Warning
2No action taken.No action
Fault / uint16
(Only visible with a ZCU control unit)
Selects how the drive reacts when a modules internal
auxiliary fan fault is detected.
Aux fan fault
function
31.36
0The drive trips on fault 5081 Auxiliary fan not running.
Note: The fault is suppressed for two minutes after
power-up.
During this time, the drive only generates a warning,
A582 Auxiliary fan not running.
Fault
1The drive generates a warning, A582 Auxiliary fan not
running.
