12. ABSOLUTE POSITION DETECTION SYSTEM
12 - 11
12.6.2 Transfer method
The following shows a sequence how to turn on the base circuit while it is off state because SON is off, EM2
is off, or an alarm is occurring. In the absolute position detection system, every time SON is turned on,
ABSM should always be turned on to read the current position in the servo amplifier to the controller. The
servo amplifier transmits to the controller the current position latched when ABSM switches from off to on. At
the same time, this data is set as a position command value inside the servo amplifier. Unless ABSM (ABS
transfer mode) is turned on, the base circuit cannot be turned on.
