and minor fault (LF) signals are output. Use Pr. 190 to Pr. 192, Pr. 195 (output terminal function selection) to allocate the
terminals used to output the FAN and LF signals.
1. Pr. 244 = "0"
When the fan comes to a stop with power on.
2. Pr. 244 = "1"
When the fan comes to a stop during the fan ON command while the inverter is running.
CAUTION
Changing the terminal function using any of Pr. 190 to 192 and Pr. 195 may affect the other functions.
