11.4 Control Data
The control data is user-specified data for controlling the positioning system.
For X-axis: BFM #500 to #599
For Y-axis: BFM #600 to #699
Caution
Do not use unlisted BFMs for changing values not described in this section.
Change of the target address and operation speed
Even if target address 1, target address 2, operation speed 1 and operation speed 2 are changed during
positioning operation, the changed contents are not reflected immediately. The changed contents will
become valid from the next positioning operation. However, the contents of operation speed 1 are reflected
immediately in variable speed operation.
For the functions to change the target address and operation speed during operation, refer to the following.
→
For change of the operation speed and target address, refer to Section 7.6
→
For variable speed operation, refer to Section 9.7
11.4.1 Target address 1 [BFM #501, #500, BFM #601, #600]
This data item sets a target position or travel distance for the positioning operation distance as the target
address 1.
*1. Refer to the section shown below for details on the user units.
→
Refer to Section 7.10
Note
• The positioning operation differs as follows depending on the procedure to specify the absolute address or
relative address.
- With absolute address: travels from the current position to the target position.
The rotation direction depends on whether target address 1 is larger or smaller than the current address.
- With relative address: moves by the specified travel distance from the current position. The rotation
direction depends on the target address sign (+/-).
• The units of the value are user-specified and include the position data magnification.
11.4.2 Operation speed 1 [BFM #503, #502, BFM #603, #602]
This data item sets the operation speed 1 for positioning operations.
*1. Refer to the section shown below for details on the user units.
→
Refer to Section 7.10
*2. -2,147,483,648 to 2,147,483,647 with Variable Speed operation.
Note
• Set operation speed 1 lower than the maximum speed.
If operation speed 1 exceeds the maximum speed, the 20SSC-H operates at the maximum speed.
• Use the override function or operation speed change function when changing the operation speed during
operation.
→
For details of the override function, refer to Subsection 7.6.1
→
For details on the operation speed change function, refer to Subsection 7.6.2
