OFF: Not reading or reading

ON: Reading completed (This is set at the

completion of receiving serial data on No.
of rotations.)

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.

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.
