Precautions for Correct Use
The Multi-function Relay Output (AL1, AL2) Function Selection (C026) is, by default, set to 05
(AL: Alarm output).
The table below shows the relationship between the relay output status when the inverter input
power supply is ON/OFF and the Multi-function Relay Output (AL1, AL2) Operation Selection
(C036) setting. Select the parameter setting appropriate to the sequence of your inverter
according to this table.

5-10-7 0-Hz Detection Signal (ZS)
• This signal is output when the output frequency of the inverter falls below the 0 Hz Detection Level
(C063).
• Allocate one of the Multi-function Output 11/12 Selection (C021/C022), or the Multi-function Relay
Output (AL1, AL2) Function Selection (C026), to 21 (ZS).
When the Pulse Train Input EA Selection (P003) is set to 01 (Feedback pulse), this function works
according to the motor rotation speed (feedback value).
