Cx2000 AC Drive
 0: continuous operation when cooling fan trip occurs.
-. Operation is not stopped regardless of cooling fan trip.
-.When I55 is set to 18 (cooling fan fault alarm), fault alarm signal can be output using Multi-function
relay.
Caution
If operation is continued after cooling fan trip occurs, Overheat trip may happen and
protective function be activated. It also reduces the life of main components due to rise in
inverter inner temperature.
 1: operation stopped at cooling fan fault
-.when cooling fan fault occurs, message is displayed on the LED and operation is
stopped.
-. If I55 is set to 17(Fault output), fault message is displayed.

Function Group 1 F67
Input voltage for 230V inverter 170~240 220
Function Group 1 F68
Input voltage for 415V inverter 320~480 380
 F67 set input voltage of 230V level inverter
 F68 set input voltage of 415V level inverter
The adjustment of input voltage will influence the voltage level when failure of inverter occurs under low
voltage
