Homing [B]

After the absolute position detection system is enabled, [AL. 025 Absolute position erased] occurs at the initial startup. Then,
ABSV (Absolute position erased) turns on. For the homing method, refer to each controller manual.

Checking the detected absolute position data

Absolute position data can be checked with MR Configurator2.
Choose "Monitor" and "ABS Data Display" to open the absolute position data display screen.
