Terminal input frequency lower limit
This function defines the minimum frequency received by the analog
input terminal (PUL). Frequency inverter will automatically filter the frequency whose value is lower than this value;
Terminal input frequency upper limit
This function defines the maximum frequency received by the analog
input terminal (PUL). Frequency inverter will automatically filter the frequency whose value is higher than this value.
Terminal input frequency gain
This function is used to amplify or reduce the (PUL) terminal input signal.

When in positive characteristic stage, lower limit of external analog input value and the pulse signal corresponds to
[F-56]
, upper limit of exterior analog input value and the pulse signal corresponds to
[F-57]
.
When in negative characteristic stage, lower limit of exterior analog input value and the pulse signal corresponds to
[F-57]
, upper limit of exterior analog input value and the pulse signal corresponds to
[F-56]
.
As shown in the Fig.
[F-56]
(fmin), the biggest analog input and the pulse signal corresponding frequency setting
means their upper limit value corresponding frequency setting, As shown in the Fig.
