Fb-18＝1 or 2 or 3 can prevent undervoltage stop caused by momentary power failure for large-inertia
loads like fans and centrifuges.

reported and the motor stops.
Fb-22 is cleared in any of the following cases: no fault occurs for continuous ten minutes after the fault
reset; fault is manually reset after it is detected; power supply resumes after the momentary power
failure.
