E3-02/ E3-03 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.

Figure 6.62 Frequency Command Adjusted by Input Gain and Bias
Bias = -25%, terminal A1 is used as frequency command input
When inputting a 0 V signal, the frequency command will be -25%.
When E3-00=0 and inputting a signal between 0 to 2 V, the frequency command will be 0%.
When E3-00=0 and inputting a signal between 2 to 10 V, the frequency command will be
between 0 to 100%.
When E3-00=1 and inputting 0 to 2 V, the motor will run in the reverse direction.
