6 Vector Control
(1) Set the Multi-function Input S1 to S8 Selection (C001 to C008) to 45 (ORT:
Orientation) and turn ON that terminal. In this state, turning ON the RUN command
causes the inverter to accelerate to the speed set in the Orientation Speed Setting
(P015) and perform constant speed operation.
If the terminal ORT turns ON when the RUN command is input, the inverter changes
to operation speed after input of the ORT signal.
(2) After the orientation speed is reached, the inverter switches to the position control
mode when the first phase-Z pulse is detected.
(3) When the Orientation Direction Setting (P016) is set to 00 (Forward side), the inverter
controls the position to the target value of "Orientation Stop Position (P014) + 1
rotation"; When the Orientation Direction Setting (P016) is set to 01 (Reverse side),
the inverter controls the position to the target value of "Orientation Stop Position
(P014) + 2 rotations" (instead of rotating the motor in reverse).
At this time, regardless of the Deceleration Time value, the deceleration time
decreases as the Position Loop Gain (P023) increases.
(4) When the time set in the Positioning Completion Delay Time Setting (P018) elapsed
after the number of remaining pulses reached the Positioning Completion Range
Setting (P017), the inverter outputs the POK signal. The POK output continues until
the ORT signal turns OFF.
After completion of positioning, the inverter remains in a servo lock state until the
RUN command turns OFF.
