7.4.2 [BFM#18, #17] Target address Ι
Set the target address I (target position or travel distance) of the 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 current address and the target address I.
- 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 I sign.
• Value is in user units and includes the position data multiplier.
7.4.3 [BFM#20, #19] Operation speed Ι
Set the operation speed I of the 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.
In case of variable speed operation
-2,147,483,647 to 2,147,483,647 (user unit). Set the value within -200,000 to 200,000 Hz when
converted to pulse data.
Point
• Set the operation speed I in the range between the bias speed and the maximum speed.
• In case of the variable speed operation and the external command positioning operation, the rotating
direction is determined according to the sign of the operation speed I.
• When the operation speed I is at the maximum speed or higher, the operation is executed at the maximum
speed. When the operation speed I 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 I is changed during the operation. When
changing the operation speed during the operation, use the operation speed change function. However,
the operation speed can be changed during the variable speed operation.
→ For details of the operation speed change function, refer to Section 6.6.
