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 HOQF to .
Note: Set reference frequency priority selection H to (HOQF/H terminal switching, default setting).
Changing the settings of two speed command parameters at a time, refer to Section 6.6.
[Example of setting: To set the frequency by applying a current of 4(0)-20mAdc via the VI/II terminal.]
