Tip: When (VS2) is used as PID given or feedback channel, the function of bipolar is invalid. At this moment,
the usage of (VS2) terminal is the same with the (VS1) terminal. Namely, when (VS2) <0, frequency inverter
think the input of this port is 0.

AS terminal input current lower limit
This function defines the minimum signal which received by the analog
input terminal(AS),frequency inverter will automatically filters the current signal whose value is lower than this value;
For example, if the factory setting of this value ‘4.00’,4.00-20.00mA input current is available.
AS terminal input current upper limit
This function defines the maximum signal which received by the analog
input terminal (AS), frequency inverter will automatically filters the current signal whose value is higher than this
value.
AS terminal input current gain
This function is used to amplify or reduce the (AS) terminal.
