will automatically filteres the voltage signal whose value is higher than this
value.
VS2 terminal input voltage gain S2 This function is used to amplify or
reduce the (VS2) terminal analog value.
VS2 terminal input zero offset This function is used to adjust the （VS2）
terminal zero point in the bipolar control mode; Its adjustment direction is
opposite to the actual zero point. If the actual input voltage is +0.5V,at
this moment, users should set the zero offset as-0.5V to let the voltage
corresponding to the zero voltage（only valid when［F-48］is set as “1”
or “2”）
VS2terminal input bipolar adjust and direction control
0: Bipolar adjust and direction control both invalid: the output frequency is
determined by the input voltage of terminal（VS2）.
1: Bipolar adjust and direction control both valid: the output frequency of
frequency inverter is determined by the absolute value of amplitude of the input
voltage of terminal（VS2）. While output phase sequence (machine direction)is
determined by the polar of the input voltage terminal（VS2）, frequency inverter
neglects its direction turning setting orders only except this order. When the
voltage （VS2）> 0,frequency inverter outputs positive phase sequence, machine
forward rotates. When voltage （VS2）< 0,frequency inverter outputs negative
phase sequence, machine reverses.
When the parameter［E-46］is set as “2” prohibit reverse, if（VS2）<0, machine
reverse, frequency inverter will operates as “0”frequency.
The Bipolar analog input signal （-10V～0V～+10V）is stipulated as following:
0V ~ +10V step is corresponding to [F-56]input frequency lower limit setting
~ [F-57] input frequency upper limit setting, forward rotation;
0V ~ -10V step is corresponding to [F-56]input frequency lower limit setting
~ [F-57] input frequency upper limit setting,, reverse.
Tips: In two channels combination, bipolar signal will carry out signed
