Command
Absolute offset preset OFF: No preset
OFF to ON: Offset obtained from multi-turn
data from Servo Driver and the
No. of initial incremental pulses
are stored as the absolute offset.
When defining machine origin, dif-
ference between machine and
encoder's origins is preset as the
absolute offset.

06 Absolute PV preset OFF: Absolute PV preset invalid
OFF to ON: At this point, the absolute PV is
stored in high-speed counter PV 1
(A600 and A601).
Note Refer to 7-7-6 Absolute Present Value
for details on the absolute PV.
07 Absolute No. of rota-
tions read
OFF: No. of rotations data read from
Servo Driver invalid
ON: At the rising edge of the signal,
SEN is output to Servo Driver, and
multi-turn data is received from
the phase A input.
