Trip
The inverter output is blocked and the fan trip
is displayed when a cooling fan error is
detected.

Warning
When OU.33 (Relay 2) and OU.31 (Relay 1)
are set to 8 (FAN Warning), the fan error signal
is output and the operation continues.
OU.31 Relay 1,
OU.33 Relay 2
When the code value is set to 8 (FAN Warning), the fan error signal
is output and operation continues. However, when the inverter inside
temperature rises above a certain level, output is blocked due to
activation of overheat protection.
6.3.2 Lifetime Diagnosis of Components
Lifetime Diagnosis for Fans
Enter the Pr-87 (Fan exchange warning level) code (%). After the selected usage (%)
is reached (out of 50,000 hours), the fan exchange warning message will appear in
the multi-functional output or keypad.
The total fan usage level (%) appears at Pr-86. When exchanging fans, you may
