4) Setting the frequency using input voltage (0~10Vdc)
[Parameter setting]
5) Setting the frequency using input voltage (0~±10Vdc)
The direction can be changed by switching between positive and negative signals.
[Parameter setting]
Set the “basic parameter frequency setting mode selection 1” parameter   to  .
Note: Set reference frequency priority selection  to  (/ terminal switching, default setting).
Changing the settings of two speed command parameters at a time, refer to Section 6.6.
