Toshiba VF-A7 Speed/torque command gain and bias, Using two types of frequency speed commands

6.6 Speed/torque command gain and bias

6.6.1 Using two types of frequency (speed) commands

 ：Speed setting mode selection

 ：Reference priority selection

 ：Speed setting mode selection #2

 ：／ switching frequency

・Function

These parameters switch two types of frequency

･Switching by parameter setting

･Automatic switching by means of switching frequencies

･Switching with input terminal

1)One frequency (speed) reference

Reference priority selection =(Default setting)



Frequency(speed) reference

Priority is given to the reference set with .

2)Switching with input terminal (=)

Reference can be switched if the frequency priority switching function is assigned to a terminal.





A

B

Frequency reference

Ａ： has priority ―― Frequency priority switching terminal OFF

Ｂ： has priority ―― Frequency priority switching terminal ON

Ex.) When the frequency priority switching function is assigned to terminal S4.
