Setup for Mode 30
Recall that V7633 is the HSIO Mode Select register. Refer to the diagram below. Use BCD
30 in the lower byte of V7633 to select the High-Speed Counter Mode. The DL05 does not
use bits 8 - 12, 14 and 15 in V7633.
Choose the most convenient method of programming V7633 from the following:
• Include load and out instructions in your ladder program
• DirectSOFT 5’s memory editor
• Use the Handheld Programmer D2–HPP
We recommend using the first method above so that the HSIO setup becomes an integral
part of your application program. An example program later in this section shows how to do
this.
Profile / Velocity Select Register
The first location in the Profile Parameter Table stores two key pieces of information. The
upper four bits (12–15) select the type of profile required. The lower 12 bits (0-11) select the
Target Velocity.
The ladder program must program this location before initiating any of the three profiles.
The LD and OUT instruction will write all 16 bits, so be sure to fully specify the full four-
digit BCD value for the Position/Velocity Select Register each time.
The absolute and relative selection determines how the HSIO circuit will interpret your
specified target position. Absolute position targets are referenced to zero. Relative position
targets are referenced to the current position (previous target position). You may choose
whichever reference method that is most convenient for your application.
