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.
