7.1 Orientation function
Chapter 7 FUNCTIONS
Relation
A044: 1st Control Method
This board is provided with the orientation function used to position the motor at a certain point during operation. This function can be used for replacing a component of the main axis of the subject machine tool for example.
7.1.1 Function outline
The orientation function maintains position which has decided with the position control after speed control operation. The action is shown in Figure
1.In the speed control operation period, inverter drives at constant speed with the orientation speed setting (P015). (Orientation mode becomes valid when turning RUN command ON under ORT is being ON.)
2.After arriving to the orientation speed setting(P015), the first coming the Z pulse is detected after that the control mode moves to the position control.
3.Inverter controls the motor to stop at a certain stop position which is set to (P014) during position control operation period.
