Preset Pr. 14 (Lost Preset F).
Pr.15 AI Lost Level,

Configure the voltage and decision time for speed command loss
when using analog input.
Configuration Function

x1
Based on the values set at In.08 and In.12,
protective operation starts when the input signal
is reduced to half of the initial value of the analog
input set using the speed command (Frq code of
Operation group) and it continues for the time
(speed loss decision time) set at Pr. 13 (Lost
Cmd Time). For example, set the speed
command to 2 (V1) at the Frq code in the
Operation group, and In.06 (V1 Polarity) to 0
(Unipolar). When the voltage input drops to less
than half of the value set at In.08 (V1 Volt x 1),
the protective function is activated.

The protective operation starts when the signal
becomes smaller than the initial value of the
analog input set by the speed command and it
continues for the speed loss decision time set at
Pr.13 (Lost Cmd Time). Codes In.08 and In.12
are used to set the standard values.
Pr.14 Lost Preset F
In situations where speed commands are lost, set the operation
mode (Pr.12 Lost Cmd Mode) to 5 (Lost Preset). This operates the
protection function and sets the frequency so that the operation can
