7.4.4 [BFM#22, #21] Target address ΙΙ
Set the target address II (target position or travel distance) of the positioning operation.
It is used only in the 2-speed positioning operation.
Point
• Operation will be as follows according to whether relative or absolute addressing is specified in the
operation command (BFM#25 b7).
- With absolute address specified:
By using the current address as a base, the positioning operation to the specified target position is
executed.
At this time, the rotation direction is determined by the target address I and the target address II.
- With relative address specified:
By using the current work position as a base, the positioning operation to the specified travel distance is
executed.
At this time, the rotation direction is determined according to the target address II sign.
• Value is in user units and includes the position data multiplier.
7.4.5 [BFM#24, #23] Operation speed ΙΙ
Set the operation speed II of the positioning operation.
It is used for the 2-speed positioning operation, the external command positioning operation, and the interrupt
2-speed positioning operation.
*1. In case of external command positioning operation
-2,147,483,647 to -1, 1 to 2,147,483,647 (user unit). Set the value within -200,000 to -1, 1 to 200,000
Hz when converted to pulse data.
Point
• Set the operation speed II in the range between the bias speed and the maximum speed.
• When the operation speed II is at the maximum speed or higher, the operation is executed at the maximum
speed. When the operation speed II is at the bias speed or lower, the operation is executed at the bias
speed. However, if the bias speed is 0, the operation is executed at 1 Hz.
• The operation speed is not changed even if the operation speed II is changed during the operation. When
changing the operation speed during the operation, use the operation speed change function.
→
For details of the operation speed change function, refer to Section 6.6.
