Description
Selects 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.
