7-8-12 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.
Parameter
No.
H06
E20, E21, E27
• When Cooling Fan Function Selection (H06) 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 in-
ternal temperature of the inverter is at a fixed value or less.
• When Cooling Fan Function Selection (H06) 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 allo-
cating "25: FAN (Cooling fan in operation)" to Output Terminal [DO1] Function Selection (E20), Out-
put Terminal [DO2] Function Selection (E21) and Output Terminal [ROA, ROB] Function Selection
(E27).

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 "Cooling fan cumulative run time monitor
(Monitor mode: 5_07)."
When the cooling fan is replaced, the operation time can be cleared by setting 0.
