Typical Set Offset Move Data Tables

Before executing a Set Offset move, set Source B for the Equal

instruction in Figure 9.1 to 16. A Set Offset command to set the

position offset to 4.0 is initiated if the float data table is:

And the integer data table is:

Using the Set In-Position Band Command

The Set In-Position Band command sets the online in-position band to

equal the specified value. The units for the in-position band specified

are position units. The in-position band defines a zone around the

end point that defines when the in-position bit is set. Set In-Position

parameters for word 5, bit 8 appear in the table below.

s = Slot number for the SLC Servo Module.

This Set In-Position Band command can be issued anytime after the

control is powered up. Refer to the example in Using the Set Axis Gain

Command.
