Orientation
The orientation function can be used as a position control response function.
Orientation can be performed with speed control during operation or while stopped.
Orientation cannot be performed when using PM motors.
Orientation during speed control
Move the motor being rotated under speed control to the prescribed machine position. By turning ON digital input
“ORT” while the motor is being run under speed control, the motor decelerates to the orientation frequency d213 in
the selected deceleration time, the mode changes to position control mode, the amount of rotation at which the
motor is able to decelerate and stop at orientation deceleration time d215 from the current position to the selected
positioning data position is calculated, and the motor then stops after rotating by that amount.
Positioning data can be selected with digital input positioning data selection signals “POS-SEL1”, “POS-SEL2”, and
“POS-SEL4” from positioning data 1 to 8 (d244 to d259). If providing positioning data with the factory default
absolute position (ABS), this will be the absolute position with the encoder Z-phase as the reference. If wishing to
provide positioning data as the absolute position with the machine home position as the reference instead of the
encoder Z-phase, by setting a position offset for the encoder Z-phase-machine home position in homing shift d242
and d243, positioning data 1 to 8 (d244 to d259) can be used as machine home position positioning data as is.

Fig. 5.3-55 Orientation while performing speed control
By turning orientation command “ORT” OFF while stopped during orientation, the motor accelerates to
the set frequency and speed control is resumed.
