In a noisy environment, it is advantageous to use negative bias to provide a noise margin. It is
recommended NOT to use less than 1V to set the operation frequency.
Pr.12-26 to Pr.12-31 can be used to set the frequency command by adjusting analog input
voltage -10V to +10V. Refer to Pr.04-00 to 04-03 for details.
