9.3.4 Adjusting gain and oset for rotation speed command
If gain and oset are adjusted when the rotation speed is set using the external DC voltage or external potentiometer,
the slope of the speed command can be changed, and the speed can nely be adjusted.
Note
The rotation speed corresponding to the voltage value varies depending on the product.

If the motor does not reach the speed upper limit
when the setting voltage is the maximum value,
increase the value in the "External analog operation

Setting example: When the motor is operated linearly in a state where the maximum rotation speed is set to
2000 r/min
Set the "Speed upper limit" parameter to 2000 rst, and set the "External analog operation speed command gain"
parameter to 400.
