4-3 Pulse Train Position Control Mode
To use this function, set V/f characteristics selection A044 to “05” (V2), and V2 control mode selec-
tion P012 to “01” (pulse train position control).
(“Sensor vector control” can be selected for 1st control only.)
Select a pulse train position command input mode in pulse train mode selection P013.
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
will be automatically brought into LAD cancel status.)
The higher the position loop-back gain, the shorter the acceleration/deceleration time.
Parameter No.
