ENCODER CONFIGURE MENU
Figures 4 and 5 show the Menus that allow for setting absolute position direction, incremental output type and
resolution. The buttons function as follows:
• NEXT
: go to the next Display Menu
• CCW/CW
: set the encoder direction counter-clockwise or clockwise for absolute position
(when viewed from front)
• QAQB/STB
: QAQB for standard 90 deg. quadrature output or STB for counter output
• NEXT
: go to the next Display Menu
• B3-B0
: set the encoder resolution according to Resolution Table
• B4
: internal sampling according to Resolution Table

*Normally, bit B4 is set to 0 for stable, smooth tracking. If it is set to 1, the encoder will respond more quickly but not as smoothly.
