P65 Criteria for analogue
input signal loss
2 When less than the value set in P56 and P61 is entered
If frequency command is set to 3(V1 of terminal) in Frq code of Drive Group and P65 is set to 1 and when
AI is less than half the value set in P56, it determines frequency command loss. At the moment, if entering
current based on the value converting 0~10V to 0~100%, it operates with the value converting 0~20mA to
0~100%.
i.e.) Voltage input: If P56 and P65 are set to 50% and 2 respectively, it operates at 5V.
Current input: If P56 and P65 are set to 50% and 1 respectively, it operates at 5mA.
P81: When the conditions set in P65 are met for the time set in P82, the inverter operates as follows.

2 Decel to stop
P77: Multi-function relay output (30AC) is used to output information on loss of frequency command to
external sequence.
