6.6 Speed command switching
6.6.1 Using two types of frequency (speed) commands
 : Frequency setting mode selection 1
 : Frequency priority selection
 : Frequency setting mode selection 2
 : Speed command priority switching frequency
• Function
These parameters switch two types of frequencies
• Automatic switching by parameter setting
• Automatic switching by means of switching frequencies
• Switching with input terminal
1) Switching with input terminal board (=)
Reference can be switched if the frequency priority switching function is assigned to a terminal.
