Position control by vector control
Forward (reverse)
In-position signal
Fig. 6-39: Positioning
● For conditional position control function by contact input, the STF and STR terminals provide
the forward (reverse) command signal. The motor can run only in the direction where the
forward (reverse) signal is on. Turning the STF signal off does not run the motor forward and
turning the STR signal off does not run the motor reverse.
● The pulse train is rough during acceleration and coarse at the maximum speed. During
deceleration the pulse train is rough and at last there are no pulses. The motor stops shortly
after the command pulses stop. This time lag is necessary for maintaining the stop accuracy
and called stop settling time.
NOTES
For the servo on signal (LX), set "23" in Pr. 178 to Pr. 189 "Input terminal function selection"
to assign the function.
For the in-position signal (Y36), set "36" in Pr. 190 to Pr. 196 "Output terminal function selec-
tion" to assign the function.
Changing the terminal function using any of Pr. 178 to Pr. 189, 190 to Pr. 196 may affect the
other functions. Make setting after confirming the function of each terminal.
