Inputs a 0 to 10 V signal. A negative signal by the gain and voltage bias is limited to 0%.
1 : -10 to 10 V
Inputs a -10V to 10 V signal. A forward Run command can be compensated by the gain and
voltage bias to become a negative signal and run the motor in the reverse direction.

Terminal A1 Input Gain/ Voltage Bias
E3-02 sets the terminal A1 input gain as a percentage when inputting 10V. E3-03 sets the
terminal A1 input voltage bias as a percentage when inputting 0V. Terminal A1 input
characteristics are determined by E3-02 and E3-03.

Examples
Gain =200%, voltage bias = 0%, terminal A1 is used as frequency command input (E3-01
=0)
When inputting a 10 V signal, the frequency command will be 200%. When inputting a 5V
signal, the frequency command is 100%.
As the drive output is limited by d1-02 (Maximum Output Frequency), the frequency command
will be 100% when the signal is 5 V and above.
