Functions
Frequency reference for the pulse train position control mode is calculated with the following formu-
la:
In the position control mode, the acceleration/deceleration time settings are disabled. (The Inverter
is automatically brought into LAD cancel status.)
The higher the position loop-back gain, the shorter the acceleration/deceleration time.
For details on the pulse train input mode, refer to the following.
