 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.

 E3-04 Retain
 E3-05 Terminal A1 Input Filter Time
Sets the terminal A1 primary delay filter time, which can stabilize the drive operation by
eliminating the interference. Long filter time stabilizes the drive but causes slow response to
the analog input signal changes.
