tions at regu-
lar intervals.
Shift the origin using a compensa-
tion value without changing the
origin of the encoder. The stop
position is a position obtained by
adding the setting value of Pr. 361
to the position command.
When servo torque function is
selected using Pr. 358, output fre-
quency for generating servo
torque increases to the creep
speed of Pr. 352 gradually accord-
ing to the slope set in Pr. 362.
Although the operation becomes
faster when the value is increased,
a machine may hunt, etc..
The orientation complete signal
(ORA) is output delaying the set
time after in-position zone is
entered. Also, the signal turns off
delaying the set time after in-posi-
tion zone is out.
Orientation fault signal (ORM) is
output when the encoder remains
stopped for the set time without
orientation completion in the state
where no orientation complete sig-
nal (ORA) is output. ORM signal is
output when orientation is not
completed again in the set time in
the state where ORA signal is out-
put.
Measure the time taken after pass-
ing the creep switchover position
and output the orientation fault
signal (ORM) if orientation is not
completed within the set time.
Set to 120s.
