Selecting a positioning mode - absolute/incremental
In the internal position control mode, you can select between absolute positioning mode and
incremental positioning mode with the parameter p29241.
p29241 0 to 3 0 - Absolute or incremental positioning mode:
• 0: incremental
• 1: absolute
• 2: absolute, positive (only for a rotary axis
with modulo correction)
• 3: absolute, negative (only for a rotary
axis with modulo correction)
Pre-conditions for using the absolute mode
The absolute mode can be used only after:
• the axis has been referenced for incremental measuring system. Refer to Section
"Referencing (Page 241)" for detailed information about referencing.
• the axis has been adjusted for absolute measuring system. Refer to Section "Adjusting
