Remedy
Lengthen the proximity dog. Or,
adjust the OPR speed to stop on
the proximity dog.
Set the OPR direction to be the
same as the push direction.
Execute push, and after turning
the torque limit on, start OPR.
Adjust the servo amplifier so that it
stabilizes quickly at OPR stop.
(1) Reduce the OPR speed and
creep speed.
(2) Lengthen the OPR time
constant.
(3) Broaden the in-position range.
(1) Confirm the input status of
proximity dog signal, etc.
(2) Confirm the setting value of OP
serch limit.
Set "Need to pass motor Z phase
after the power supply is switched
on" in " Function selection
Pr.397
C-4".
Set the value of software stroke
limit within the range.
(Refer to Section 10.4.2.)
Execute the OPR.
Replace the QH74MH.
