Reference Priority Selection

Either Frequency Mode #1 or Frequency Mode #2 may control the output frequency of the ASD. This parameter determines which of the two will control the output frequency and the conditions in which control will be switched from one to the other.

Settings:

Frequency Source #1

Frequency Source #2

Frequency Source #1 Priority

Frequency Source #2 Priority

Frequency Source Priority Switching

The Frequency Source #1 or #2 setting specifies the source of the input frequency command signal. These settings are performed in F004 and F207, respectively.

If Frequency Source #1 is selected here, the ASD will follow the settings of F004. If Frequency Source #2 is selected here, the ASD will follow the settings of F207.

The Frequency Source #1 Priority and Frequency Source #2 Priority selections are used in conjunction with the Mode #1/#2 Switching Frequency setting (F208). Parameter F208 establishes a threshold frequency that will be used as a reference when determining when to switch output control between the Frequency Mode #1 setting and the Frequency Mode #2 setting.

If Frequency Source #1 Priority is selected here and the commanded frequency of Frequency Source #1exceeds the F208 setting, the Frequency Mode #1 setting has priority over the Frequency Mode #2 setting.

If Frequency Source #2 Priority is selected here and the commanded frequency of Frequency Source #2 exceeds the F208 setting, the Frequency Mode #2 setting has priority over Frequency Mode #1 setting.

Frequency Source Priority Switching allows for a preconfigured input terminal to activate Frequency Source #1 or Frequency Source #2. Any unused programmable discrete input terminals may be programmed as the Frequency Priority switching terminal.
