Cooling FAN Control Method Selection
To extend the life of the cooling fan and reduce the noise from the cooling fan, the cooling fan can be
stopped according to the internal temperature of the inverter when there is no motor output.

• When Cooling Fan Function Selection (3008Hex-07Hex) is set to “1: ON/OFF control effective,” the
cooling fan operates during motor output, and, when the motor is stopped, the cooling fan operates
until the internal temperature of the inverter is at a fixed value or less.
• When Cooling Fan Function Selection (3008Hex-07Hex) is set to “1: ON/OFF control effective,” the
ON signal is output when the cooling fan is in operation and the OFF signal is output when it has
stopped by allocating “25: F
AN (Cooling fan in operation)” to Output Terminal [DO1] Function Selec-
tion (3005Hex-15Hex) and Output Terminal [ROA, ROB] Function Selection (3005Hex-1CHex).

Cooling Fan Life Warning Signal (WAF)
The number of hours of operation of the cooling fan is counted. The cooling fan is judged to have
reached the end of its life when it exceeds 87,000 hours (10 years) of operation, and WAF (Cooling
fan life warning signal) is turned ON.
The operation time of the cooling fan can be monitored by Cumulative Run Time of Cooling Fan
(3008Hex-2CHex). When the cooling fan is replaced, the cumulative run time can be cleared by set-
ting 0.

Life Alarm (LIFE)
For models with a main circuit capacitor, cooling fan, and inverter capacity of 18.5 kW or more, if any
of the capacitors including electrolytic capacitors exceeds the life judgment standard, the LIFE termi-
nal (30: Lifetime alarm) is turned ON. In addition, the lifetime alarm (alarm code: 67) can be output as
a minor alarm. For details, refer to 8-8-23 Minor Alarm Selection on page 8-95.
